  1. Wow this goes on forever and no conclusion lol. It’s not snake oil but can help or harm. depending on your system in all. Things Not to do dont use optical couplings or network extenders they may be ok but may not. In digital less is better almost always. it’s exp and better to just use a cat6a shielded or cat 7 shielded it’s Rfi and Emi shielded and don’t buy online unless it’s a real bender. China has completely taken over wire. While the above is true all varies and your system may benifit and others may not. This varying can be accounted for but has too many variables to know before. In general the one thing that is snake oil is to market products of convince as a fixer this they are not always. Truth and false. Does jitter or noise get passed on yes always can jitter or noise be filtered yes can a reclocker fix jitter or noise yes does a naa or raat fix noise this is where it gets fuzzy for the most part no but there are some goods as well. Noise comes in many shapes so some do get fixed others pass along. Does a fast pc make more noise no for the most part does running many programs so a pc make more noise absolutely yes keeping a pc based naa running min programs is a must. Does a a Nuc help yes but this may not sound well on all systems it’s Linux based this alone adds thinness as windows has a more whole sound raspberry pie and humming boards good or bad yes and no. Linux based Devices don’t need lps supplies yes. But using them does give you an inprovemt does a windows based pc or Nuc need a lps yes yes yes. In windows anything an LPS is a must or the sound is horrible. But again systems depending the chain get effected more or less. The above is facts. It fiction and I don’t sell anything and all above has been tested by me. Bash on groupies
  2. How does it iso late ? There was a a few made that did it not made anymore. The ones I see use a chip and claim iso. But the few tried were not good in sound. Paul’s and others do alow ext. but why not use humming bird or Nuc on a cheap lps supply.
  3. Hello Steve post the link when you can.
  4. How likely are you to part with the audio note and how much would you get from it. My point is to have two DACs is not a good idea and one for each format even harder to make you happy. Consider each dac has its own house sound and you switching back and forth. You will not be a happy camper lol.

    USB cable comparisons

    There’s atleast one more item not mentioned that maybe worthwhile to say. The dac input and usb output have an impendance. This mismatch that we can hear in various forms of jitter or noise is a part of the usb sound tunning effects. I have heard usb Cables sound broken and great in another server same dac. I first observed this in a coaxial spidif cable I use CIEMS with a dac and amp in a pouch at one time I used a DAP as the source and later an iPhone. Not owning a real spidif cable I used a audio interconnect wow was there a varying in sound. I ended up buying a CUST cable form empiricle audio made by STEVE Nugent. This yielded the best sound I could have. This was about 5 years ago. A dark time in digital with some glimmer of lights glowing in the distance. The same remains in a AES cable the bal cable of spidif. It’s truly a shame it’s not used and we are left with usb. Network or naa or there variants are also good but for me not at the level Of a good tunned usb setup

    Totally agree it can make or break.

    USB cable comparisons

    We should not disallow others comments there are many factors to consider how much or any to some. Does anyone have an understanding of why usb Cables effect the sound ? I can doa few quotes but it will not matter to most. THe source used makes the biggest change and after that most DACs. While there are some exceptions it’s mostly as I say I feel. . Why do I put the source first coz most all DACs will not Sound best without it. Beyond this is the usb Cables we use. All usb Cables seem to have a sound so to admit this is tough for me and most I don’t feel exp Cables are needed always but clearly some made are better for over all sound. I kind man who Owns some nice stuff was driven mad with ground isuses. It took me many weeks as I helped him fix his many issues. Lastly it was his usb cable to fix. I truly feel all of our audio devices need to be electrically isolated it few do this. He ordered a cust usb cable with a power cutter built in and a Recomended usb iso device. It was the last step to true happiness. Not all have systems that can hear the changes to the levels it may happen. To accuse them is degrading to them and cannot help the Person. Laslty are any usb Cables made for us bad. Absolutly yes lol I have heard them in my system. But others love them lol. Dont take my comments as trolling it’s. It meant to be. It’s just pure honesty. Tough to swallow now the poster who needs to reboot a good idea and of you hear it it’s ok. Dont let others make you feel odd. It’s his most try to make me feel as I help them lol. The reason why is complex and I am not sure why it’s in yours. If you post what your sever is I might be able to explain why. But do reboot of you feel it does. Enjoy
  8. By accident I have found a website that seems to have the best sounding red book cd,s I ever has played. I own SHM , super cd,s and the like .all very good spend quality . Maple shade is beyond this signiifcly to play one is the heir the full potentioanl of your system. Andy McKee total track top hat is a free mp s download , yes MP3. The cd is red book. Download it and play it and then comment . http://www.mapleshadestore.com/ while they sell many products and I have no affiliation or own any products except music . The sound is amazing a word many use in audio but rarely is this word needed. In this case it's not a good enough word.

    Lampi pacific in the House

    PART 2: It's been more than three weeks since the Pacific was installed in my system in this time I have played my now all new music hours each day . My comment of all new music is for me the most dramatic part of this dac. What I mean by my music is all new is a window into reproduction that seems correct and untainted by a house sound of the dac. No dac I have ever had in my system nor ever heard did not have a house sound. Many post of the virtues of a great dacs' house sound . In the past I too was onboard with this concept as a virtue as well. Over time a good audio bud has helped me bring my system to a new level of transparency . Let me describe transparency because some use this very needed word with varying interpretations. For me it's a clear window , with glass so clear that any changes are observed without having to look for it. For me changes that are not noticed immediately are ok as some changes for me need a few mins to a few hours to really be digested. Once I learn it , it now becomes one more facet in pursuing better sound. There are many aspects of sonic change that's good , bad and ugly but any change must be heard and understood. Have you ever played a song perhaps on Tidal and now remastered on MQA . At first play it may wow you or underwhelm you. This is the immediate reaction and this may be the final one, but it never should be the only one used for final judgement. What this means is that time is needed for our brains to learn what's new to your senses. I have many times loved or liked fast, but always over time there is more depth underneath this initial reaction. A transparent system allows for minute changes to have layers or levels of details that produces an end result of "like or not". My perspective of perceived changes may not bethe absolute reference, due to many reasons: systems vary greatly as does our own hearing . So how does one person write a review that can be read and then fully appreciated by others? My answer is a deep explanation of each change, and my own explanation of the words I use. After all, there really is little in audio we all agree on and even the words we use to describe are heavily debated. Listening to the same music on multiple systems is essential for me. So how does one accomplish this large task? For me, I use various forms of playback systems I own and know very well. Headphones are a great tool and of course I also enjoy them. Only a few headphones I own or have heard yield sound I feel is like my massive IRS V sound . No headphone gives the wall of sound or the "you are there" illusion like these speakers. However, some get close enough in staging, but more important is the varying transparency that I use as a tool/guage. I define a varying transparency as the varying levels of details each system yields, but even in this variance there is enough commonality to show me what’s real and what’s made up. Some dacs add bass on every song. Some add false dynamics as well. Playing my known music on many setups gives me views I need to show me a better truth in what’s real or not. The most speaker-like headphone I own is the Hifiman HE6. A great headphone that is very difficult to make sound right. A big amp (far more than most headphone amps) is needed. Once you have it done right it's a whole new vista into the music layering that gives me many details I can use to compare to my speakers . So why use headphones or even more than one system or amp? This is far more important than you may think! The Pacific dac in my opinion has little to no "sound" of its own and just by rolling tubes shows any variation in reproduction . The answer is to confirm what the music has that is common to more than one setup. This shows me more of what is originally there and less of what is put there subsequently. Are there parts of the music put there by the playback chain? This method and others are used as a baseline for any dac I use. Using this method with other dacs, amps, headphones, CIEMS gives me much more details to judge by. Each song has its own mix of sound and album to album must show very prominent changes. Have you ever played a few songs from one album and noticed big changes from one track to another? Well, any one track to the next should have changes, some even as the mix is changed during the song. Transparency and playing this music in different setups shows me what's really common to all music. Many dacs pick and and choose what we hear. My conclusion is the Pacific does not intrude, it simply passes through only what's in the music. In many ways the dac is passive; this is a word I'll bet no one may have used in a description yet it's a very big virtue to have. Passive does not mean it does nothing. In my terms, it's the ultimate of non invasive sound reproduction . After all, we want to hear our music reproduced without a flavor. In using many forms of playback and many dacs I can better confirm just how transparent or passive this dac is. Tube rolling any Lampi is a virtue that may seem complex and one could even ask why do I need to do this. When you go to a steak house and order your steak, do you let them pick the cut or how it's cooked and what sides it comes with ? In owning many dacs over the years each having a steadfast sound always puzzled me and using an EQ is just too dark a path to go down . So all that is left is the sound THAT manufacturer feels is best for all. That alone is scary for me. Now as I have said the Pacific is so transparent, it can have a varying sound scale by rolling tubes . Each set of tubes has its own sound, not massive, but enough to vary the sound to better tailor to anyone's system . We all have varying likes and playing varying genre some may feel needs an appropriately matched tube type. Tube rolling yields a treasure trove of sound changes that is very rewarding. In the next installment I will delve into tube rolling with previous Lampi dacs and with the Pacific . The Pacific brings tube rolling to a new level of refinement .

    Great question and coming in posts later and I will be doing direct comparisons as i own two others.

    PC - cheap optimisation?

    Find some of my posts and read them. And don’t care what others say of my comments then ask me for advice. I have tried so many times to help in this and get flamed from makers of devices or even worse quoting what others say so it must be true lol. While a. World class two of setup is above 8 k a really good sever can be have for less then 1500. A few simple methods must be adhered too. And no exp clocks needed
  12. While I am going to get bashed and feed back filled with bull. I'll post this anyway in the hope some learns from it. You want a full size atx , not ant micro , mini or nano. The reason is sound , the why is emi and rfi of the parts on the board. You may or may not need more than one PCI slot . If any PCI slots that mY be needed a lan card is a must have. It frees up CPU and better network performance yielding better sound. A 4 12 volt CPU buss feed and plenty of voltage regulators large ones are needed. At present top end gamer boards are best. Crowd source some of the above and I am in. Most here are looking and thinking case size and not sound. If this is about looks then why bother it's about sound for me and always. A M2 slot is cool two are not needed but ok if it has them. Anyway there are some real world comments enjoy or give replies back either way it's facts I just posted. Ps you don't need a USB audio card nor clock upgrades on the main board but being able to have them on the two clocks is a good feature to have. Key points isolation and many great regulators are key overall.

    Lampi pacific in the House

    My dacs in the House asside of the new pacific dac are MSB stack headdac golden gate BIG 7 point to point reavamped in late 2016 commemts comming. The dac comes with a new set of recardo Kron 300B amd a recardo Kron 5U4G i alao have a barrage of tubes I have rolled in that will also be commented on for others as a guide
  14. My Pacific Voyage by Al Dattolo Intro: As many of you may know from my posts, I have been a Lampizator fan for several years and own a couple of their DACs. I have been enthusiastic about this small company and it unique offerings for some time and the announcement of the Pacific piqued my interest deeply. About 3 weeks ago I got an offer I couldn’t refuse when my friend, Fred A., who happens to be the North American Distributor of LampizatOr, offered to loan me his personal Pacific while his home was being renovated. I quickly accepted the offer and setup a day to meet up and collect it. The Pacific came in a large heavily reinforced transport case, similar to the kind used for roadies in shows. Inside it was heavily padded. Shiny? Yes. Bling? Yes-- but not over the top. It's gold finish is elegant without being over the top gaudy. The Riccardo Kron tubes in their custom boxes are another “perfect 10" in my book as well. For me these choices seem right for a flagship product. Upon getting the unit placed it in my rack I let it warm up for two hours with the Riccardo Kron edition 300b and 5u4G tubes it came with. Background: Before diving straight into my review, I want to say a little about myself. I have spent the better part of my life pursuing high end audio. As a teenager I built my first stereo from parts bought from a local audio store called “Lafayette Electronics”. Does that name sound familiar? It should--they were "da bomb" many, many years ago. I remember fondly those days as I had speakers, headphones even a customized car stereo. In those days there were three ways to play audio: vinyl and tape and of course a radio. In my view it's well merited that to this day both vinyl and tape remain the pinnacle of high end audio reproduction . My present system is made up of collection of both new and old components. Some say the equipment of the past was better than the present in many aspects and that more often than not newer is not better, and I believe there is merit to this thinking... When solid state came out I was there and when the shiny discs came out I was there too. Back then I had all (built by me) David Hafler stuff. Amps , preamp , equalizer too. What I noticed back then was a heightened level of detail relative to what I’d experienced before. Sonically speaking, I’ve always been somewhat of a detail junkie and, as my equipment improved over time, complexities and trade off associated with the chase became apparent. As a final introductory note: Honesty isn’t always welcome in forum posts, and I do, on occasion, catch hell for it. I never post about things I have not tried or do not understand, unless I am attempting to learn something for myself. My current configuration is as follows: Speakers - Infinity IRS V completely revamped by me. New magnets , wires , new cross over (now external) designed and voiced by Arnie Nudel himself (what could be better?) Also, a new balanced active cross over also by Arnie and along with a new PSU . All work was done by ps audio. I also commissioned a analog phase shifter/adjuster for the woofer towers . Amplification is a heavily modified Aragon 4004 Mkii with custom power supply scheme. Preamplifier duties are handled though the analog inputs by my MSB Platinum+ 4 DACS : MSB Platinum plus 4 new USB input, LampizatOr Big 7 (2017 vintage), a custom LampizatOr Golden Gate Headdac with super clocks , R2R Pcm384/DSD256 , chipless DSD512. It was made to be neutral for headphones and has a driver tube with a bypass switch . It's SE with many tube rolling options . Source - My server is a self built dual PC setup. My player PC hosts Roon while the computer interfacing with the DAC hosts HQ Player. Both computers use Windows SERVER 2016, Audiophile Optimizer, a full size Gamer Motherboard with 4 feed digital controlled cpu voltage reg with a 3.5ghz Xeon cpu . This is for both player PC and dac PC. A custom NAS (actually a storage area network -SAN) with a full size main board 6 core cpu . 4 spinning drives holding about 20TB of music. 4 external LPS power supplies are used for all and many voltage bus feeds for all drives and on board devices. Enterprise grade LAN cards and LPS. Network switch on its own separate network. Review: I believe the servers I use allow me to extract the very best a DAC is capable of, although this can be a double edged sword at times. It leaves nowhere to hide for the limit of the dac's capability: noise floor, imaging, micro and macro details. and finally dynamics. Upon listening to the Pacific for the first time in my system, it showed me much more details than I normally have in my system and seems not to have a sound of its own. What this means is each track has its own sound. A good friend explained that is what Ultra Hi-End audio reproduction should be. This dac has this in spades! As a result of this, my personal reference tracks were like brand new to me, despite hearing them hundreds of times. The resolution I am describing is more complex than just more sounds. The sound I have been experiencing gives me whole new layers in playback. I can hear the vocals slightly change in sound level even the piano keys intensity is there. To say the Pacific was better than my own reference HeadDac is an oversimplification, to really describe it I needed many hours to get into words what's better. From the Moment I turned the Pacific on it was clear this was levels above what I had ever had in my system. In fact, even the very best, cost-no-object, DACs in world class systems, don't have the Pacific’s level of refinement. Let's define refinement on my terms, it means cleaner sounds, more bloom around the notes or vocals, yet not pointed nor thin. Notes or vocal decay is what attaches me to the music and as you get hyper details, it's usually thinner by nature. The gift of refinement is to have both details presented along with the note decay and sustain that makes allows a piece to retain it’s weight . The sound this dac gives is the most detailed I have experienced, yet it truly retains the decay! Not even some very expensive dacs I have heard give this level of refinement. Noise floor: this is of the most important in any ultra high end system. Silence is what we want. My system is fed from a 10kw balanced isolation transformer. It is completely isolated in the ground plain of my home or power grid . This gives my setup a base noise floor much lower than the use of typical room power. Most don't use or understand the vast inportance of this power distribution system . It's how I am able to hear the musical fine details that I speak of. While the Pacific will take most any setup to the next level of sound, in my own system I hear just how limitless this DAC’s noise floor is. To hear the vocalist breathe and form their next word makes me feel I am at the mic feed level. No dac I have had or heard gives this kind of "you are there" feel. To hear the slightest change in inflection of a piano while singing is what ultra hi end is about layers that seem so separate yet from the same song is almost unnerving to me. I have told others that any horn or string Instrument has a rise and fall of each note. On a saxophone or horn I call it a “croak”. It is the start of a note as blown onto the reed. Smearing of this is typical in lesser dacs as they can't seem to get or hold this kind of detail. Part of this may be related to their reproduction of decay–lesser DACs, even backed by the best of servers, do not and cannot present this no matter what I do. I don't build servers commercially, rather it is a labor of love for me and I have restlessly sought to extract additional levels of refinement in them. In doing so I know what makes a dac sound great, but the dac can only play at its own inherent limit. The Pacific dac gives me the most detailed note decay, yet still as fast I have ever had in my system. What is needed in any ultra high end system is just a handful of parameters: clarity, fast dynamics, micro and macro details (note decay resides in these two) and low noise floor . Seems like a small order, no? Notice a house sound is not included in the list! No dac should have house sound but most do and in the past even Lampizator was guilty of this as well. The Pacific, however, distinguishes itself in that it does not. Though difficult to describe, it is simple to appreciate once you it in a system that can give you this. To be continued with next installment very soon

    SOTM sCLK ex

    Lol I am sorry for my poor spelling and grammar I meant don’t use essential version. And it does sound different as it has many more backgrounds apps running. I use gui always to avoid just terminal commands When you install win server unplug the network cable I imagine your using a thumb drive ? when it’s installed do the below in search type sconfig make two changes 5 and 10 one is tilemitry a must do select security next is updates sel manual then go to service mng and local then options or settings point is stop it from starting at each boot. Now reboot find on the web two kinds of script stops one is Telimitry the other I can’t remember the name but it has other script stops. After then load the rest of your stuff now power why larry says this is amazing to me just look at the size of the tiny dc atx as compared to the 400 watt one. The larger one has less ripple and more separate dc bus voltages do you use the same dc power for both OS and music driives ?
