Hi Dynobot, A linux question, regarding the unbind, what's the advantage in using than using the rmmod? Thanks

Hi there, Not follow up this thread for months. It's been quite active. I'd like to raise a question. I am Lv7 user and recently one of my friends gave me an PCM384 album. I played using USB and found that there is a white noise in background (kind of like raining in background). Does any Lampi DAC user tried PCM384 file? I just curious does it support or not. To me, I don't care at this moment the support of PCM384 as I am happy with PCM44.1 at the moment.

I hope so, but it seems the codec is now owned by Microsoft, does it require commercial license to use? High Definition Compatible Digital - Wikipedia, the free encyclopedia

Your transport has tube buffered for SPDIF output, it is in fact a DDC with tube buffered. I tried and compared with the USB of my Lv7, which just like what you said. The transport sounds more analog feel without loss in detail when playing PCM 44.1, so I prefer using the transport for PCM 44.1.

Good question

Hi, In the latest version: 2014-05-22: daphile-14.05-b220905-x86_64.iso & daphile-14.05-b220905-i486.iso The linux kernel is not RT enabled. May I know any of you compared with the previous RT version and hear any difference?

Hi Kimmo, It seems that the latest version has unify the URL to http://daphile.local'>http://daphile.local .Am I right? Because I was able to use http://daphile on my Windows 7 (w/Chrome) to access to Daphile but now I need to use http://daphile.local'>http://daphile.local instead.

Few suggestion for feature: -Add a text message under "ready to connect" telling the user which way it is connected, no matter the screen turns off after 1 minute. It allows user to know which way to connect to. Because there are 3 ways that daphile connects: wired LAN, wifi (as client), wifi (as hotspot with own wifi network). Letting the user know which network it hooks to helps minimize connection problem -Allow user to press a key (or any key) to show up the screen again after one minute, and allows timeoff, say 30 seconds, after the screen shows up. This helps user to read the connection information "again"

I see, I have not tried that. I only tried by playing some classical music. Let me see how to do such test. My version is single mode.

I am running with kind of latest version of Intel i7 and Asus MATX motherboard. Yes, it is pcie (x1) so unfortunately you may need to upgrade the PC if you wanna setup one. This fiber converter allows end user to mix and match (kind of). As you see, there are three parts here: 1. Host card (pcie), which is put inside the PC chassis 2. Receiver, the small aluminium box 2. Transmitter on both host and receiver For the receiver, you can buy one that comes with several slots of PCIe/PCI. That allows end user to put whatever card they want, not just connecting to USB devices. That's more expensive than my USB receiver of course. For transmitter, you can choose either single mode or multimode, both are dual cable version as I know. Single mode suppose support longer distance and multimode is cheaper and supports shorter distance only. This kind of transmitter is based on an industry standard called "STP". I am not technical enough to further describe the meaning, but that means you can buy your own transmitter as long as it is STP compliance I believe. They do have two model that recommended me when I buy, so I bought one of the two models in local computer network equipment stores. It's more expensive buying this from them that's why I bought locally. In other words, the host card and the receiver, you need to buy from them (via email to Adnaco, the email address can be found in their web site). You can also buy whole set from Amazon if Amazon ships to your place (Amazon not ships this item to my place). For transmitter and fiber cable, you can order from them as well, or you can check the price elsewhere as it is industrial standard. Sorry, I do not understand what you mean, because English is not my mother tongue. Would you please rephrase in a more layman way? Thanks

Two weeks ago I met a friend and borrowed the SotM USB card. Today I just compared it with my AdnacoS3B. Due to the difficulty in swapping PCIe card inside the Steracom chassis, I chose another fanless ITX board for comparing two cards. The board is powered by a Pico-DC with 12V LPS. I have another 5V LPS for powering the AdnacoS3B external case (the end point) and the same 5V power supply provides USB power to SotM card as well. I also compared with the on-board USB output (USB3.0) Some highlight of the comparison: 1. on-board USB vs SotM - SotM runs out obviously without any doubt, the sound quality improves immediately in every aspect. 2. SotM vs AdnacoS3B - Difference is subtle, I took several rounds of AB testing to get more differences. One major difference is that the SotM card seems lack of a layer of very low frequency that makes my sofa vibrate. Don't misunderstand that such vibration is not in large magnitude like AV systems but it just no that vibration for the same track when using SotM card. 3. The other difference is, SotM presents music in a more "leisure" way that sound is a little bit smoother than AdnacoS3B. 4. The level of quietness are very close for both cards (in this setup) that I don't want to further justify. Conclusion: 1. In terms of price and performance that the SotM gives, I think it already done its work. 2. AdnacoS3B on the other hand is a bit over priced, but it gives something (better frequency range response) and it seems more tend to "precise/neutral" way of presentation of music, while SotM is little bit more musical way of presentation of music.

Sorry wisnon, I have not tried Big7 yet.

As told by the HK distributor of Lampizator, we (HK) have the world's first Lv7 two boxes and Big 7 user.

Wow, really no secret and no boundary on the Internet. seatrope, nice to meet you! Fred, the US distributor, is a very good service distributor. My another friend in HK who've ordered Lv7 same time as me ordered from Fred, and he got very very good service (proactive email with most updated status, fast response and best effort in replying to all my friend's emails). Luksaz is a very busy man so a good distributor who helps answers all those technical questions, manufacture status and shipment detail is very crucial. Luckily, there's a HK distributor now who is also a very good man. I look forward buying another Lampi product thru his help in future. Let me share some of my views: I don't buy the concept of upsampling (either software or hardware), because in my knowledge domain, I think upsampling in the best case just add some more information into the audio data to make human's ears feel more comfortable, it's like doing "auto contrast & brightness" to a photo: good for some photos but takes time. It is beyond the PCM on my Lv7, not far beyond but it beyonds for sure. As said above, I don't buy that so I've never tried. I guess the result would be positive, but similar to do the auto brightness/contrast to photo, it takes lot of time to do and it also takes lot of space. Currently I put my PCM music onto a 500G notebook hard drive so that I can put it into my CAT. I put the DSD data on my NAS because they are too large. That's a must buy item if you are a 2A3 user. It's not cheap and it also get quality issue. I got my pairs at about $320 USD (with 1 year warranty). Few days ago, one of my audiophile friends told me that there're quality issues from the PSVANE tubes, I am not sure my PSVANE 2A3 is a good or bad pair. Let's assume it is not up to standard, it sings very very well. It seems that the 2A3 on my DAC is not running in full load like it runs on a power amp, the tubes not very hot when running that I can keep placing my hand touching it. That's why I guess the quality issue of tubes is not obvious in my case.

I see, thanks.
