Popular Post gstew Posted April 18, 2018 Popular Post Share Posted April 18, 2018 On 4/3/2018 at 3:30 PM, Superdad said: They certainly do vary. What is interesting is that some of the quality SMPS units actually suppress/absorb/filter(?) noise which is already present in the wall. Here is a short video demo I did with the Entech Powerline Noise Meter and the Mean Well SMPS (which we have shipped thousands of, with USB REGENs, ISO REGENs, and the original UltraCap LPS-1). Not shown is that after that I tried the same thing with an Apple 12W iPad USB charger block (not the tiny iPhone size charger cube), and the noise went up not down. I observed a similar effect of lowering the indicated line noise (also with an Entech) using my DIY'd 4-LPS-1 supplies AFTER replacing the good rectifier diodes with better ones AND beefing up the AC line filtration. Indicated noise went down when I plugged the revised units into the AC sockets, whether energizing LPS-1's or not. AND there was a corresponding SQ impact when I put them into my systems, again whether energizing LPS-1's or not. GOOD to see that's not an isolated situation. Greg in Mississippi P.S. It reminds me of a report by Peter Moncrieff of IAR many years back when he was doing a survey of mid-level preamps. He report that while he was preparing for the survey , his system was sounding 'off'. He then checked a lot of things in and out of his system and finally identified that one of the preamps in the survey (at that time he had them all plugged in to both warm up and break in) pushed a sufficient amount of noise back into his AC lines to reduce the SQ of his setup, just by being plugged into the AC, whether connected to his system or not. This report was the first by what I consider a reputable source of the impact of noise introduced to the AC line by equipment not connected to one's audio system impacting the SQ of that system. look&listen, MikeyFresh and Cornan 1 1 1 Everything Matters! 2 systems...

Popular Post tboooe Posted April 23, 2018 Popular Post Share Posted April 23, 2018 @Superdad @JohnSwenson...I must commend you on another great product! Today I received my LPS-1.2. I got it because I needed another 5vdc power supply in my system to power the IsoRegen. I already own the original LPS-1 which powers my SU-1. I was skeptical the LPS-1.2 would sound any better. Boy was I wrong. Without changing anything else in my system I swapped in the LPS-1.2 to power my SU-1. Immediately I heard more definition and clarity. Notes sounded more tight and more energetic. As a result the music is more engaging. This was the magic Ive been missing since adding a switch to my system because i had to remove the direct connection I used previously between the HQP PC and the NAA. Needless to say, I am very very happy. Thank you Uptone!

I wasn’t really expecting to be blown away, but boy was I wrong. Initial impressions: - Everything has been brought into a tighter focus - A veil has been stripped away, with improved clarity and lower noise - Voices and instruments are more present - Greater separation between instruments - More snap and pop to dynamics I’m thinking I should just have Alex keep my credit card on file so he can just ship me whatever new product they come out with. LOL. Lastly an additional big thanks to Alex for getting it to me so quickly in light of the challenges recently reported. Much appreciated.

Tommy & Kenny: Thank you both so much for your kind words and for sharing your impressions. It means a lot to us and makes worthwhile the recent long days and weekends spent catching up. I’m pleased to report that a lot of units went out today, and by Thursday another 90 units will go out, at last catching us up with all back-orders. These 250 are going really fast—there will be only about 40 left at the end of this week. Am already buying parts for the next run. John is working hard on a number of things—including final assemby of his computer-controlled surface mount parts placer, to use for prototyping of complex PCBs at home. (Placing hundreds of tiny parts by hand is extremely tedious!) He already has and uses a desktop vapor-phase reflow oven, so completion of the parts placer will be a big deal for us. Maybe he’ll post some pics of it in a few days. It is really cool! His first project with it will be placement of all the parts for his clock maker/blocker/isolation board for the advanced test system he is building. So stay tuned! kennyb123 and beautiful music 2 UpTone Audio LLC Link to comment
hifiveharry Posted April 24, 2018 Share Posted April 24, 2018 I received my second LPS 1.2 the other day. The first went on my IsoRegen and I still can't believe what a nice difference it has made. I truly think it kept getting better for 4-5 days. I put the second one on my UltraRendu and gave it a day of play time before I sat down to listen. WOW AGAIN!! It makes about the same bump in sound quality as the first one did. I'm excited every time I listen! Digital has never been better! Blake 1 Link to comment

hifiveharry Posted April 25, 2018 Share Posted April 25, 2018 I did have the LPS-1 on both the Ultra and the Iso and was so thrilled with the sound I was getting I really didn't want to change a thing. Curiosity got the best of me so I ordered a LPS 1.2 just because EVERYTHING I have ordered from UpTone has improved my system. I put it on the IsoRegen for a listen and was blown away! Ran to my computer and got in line for another LPS 1.2 to energize my UltraRendu. The Ultra reacted the exact same way with an equal gain in sound quality, soundstage, and bass articulation! The cumulative effect of both pieces now powered by the LPS 1.2's is breathtaking! Every plucked string, bass whack, etc, becomes an event. Not in your face" look at me". Just more explosive with more substance thru the critical midrange. My system still has that " 13th row" cohesiveness to the music, but now has that " 4th row" jump factor that will have you laughing out loud when you hear it. Like Nike says, " Just do It". johndoe21ro 1 Link to comment

oneguy Posted April 26, 2018 Share Posted April 26, 2018 I have an LPS-1.2 that registers over-current when I connect it to my SU-1 set at 5v but my other LPS-1.2 does not do this when connected tot he same SU-1. Both LPS-1.2s work with my ultraRendu at 7v. It sounds like its faulty and needs to be replaced unless there is some reason for this happening that I am missing. Anyone else have any ideas?

That is strange since the SU-1 probably draws less current than an ultraRendu, and a given LPS-1.2 has the same current limit at all output voltages (each unit is certified to 1.1A, but actual overcurrent trio point will vary from about 1.11A to 1.19A). So how about you contact me directly and send the unit in question back for bench testing? If it acts strange in any way we will of course exchange it for you. Thanks, — Alex C.

bit01 Posted April 27, 2018 Share Posted April 27, 2018 Rated at 2A continuous but 20A transient, the Paul Hynes SR4 (@9V powering the LPS-1.2 @7V (likely against Paul's wishes) does combine the two PS's strengths. I get a listening experience with good (LPS 1-2) resolution and reduced 'digital stress' (SR4) when compared to just the smps/LPS-1.2 pairing. The SR4 is only warm to the touch. At 12V it hardly gets warm but I get a slightly 'harder' sound out of the combo! SR4 @9V (cu DC lead)->LPS-1.2 @7V-->uRendu-->USPCB>NAIM DAC-V1 Link to comment
SWL3600 Posted April 28, 2018 Share Posted April 28, 2018 A custom 7.5V/4.8A/36W world-voltage-compatible tabletop SMPS for "energizing" the UltraCap™ LPS-1.2, along with a 45cm AC power cable (standard IEC plug one end, USA wall plug at the other—international buyers can cut and put a local plug on or just use any standard power cord I copied this from the Uptone site. I thought I remember reading that this is supposed to be better than the ones that came with the ISO Regen and the standard Regen. Is this the case? Can it now be purchased independently without the LPS-1.2? Thanks! Link to comment

bit01 Posted April 28, 2018 Share Posted April 28, 2018 The new smps has more power as you quoted (36W) vs 22W for the Mean Well. The LPS-1.2 consumes more power than the LPS 1. The -ve of the output pin is now internally shunted to earth in the new smps. Link to comment
SWL3600 Posted April 28, 2018 Share Posted April 28, 2018 So is there an advantage to using it with the LPS-1? Link to comment
Superdad Posted April 28, 2018 Author Share Posted April 28, 2018 17 minutes ago, SWL3600 said: Also, if it is supposed to be better.....better how? Aside from being a higher wattage unit (required to supply the expanded output voltage range of the new generation LPS-1.2) the new SMPS is internally "ground-shunted," so it does not output any high-impedance leakage. Our UltraCap supplies (both the LPS-1 and the LPS-1.2) completely block the path of low-impedance leakage, but because we use transistors (which have a few picoFarads each of capacitance) to alternate between ultracapacitor banks (instead of mechanical noisy relays), we discovered that some of a lesser-known form of AC leakage (high-impedance leakage) was able to pass through the UltraCap units. It is easily dealt with by shunting the AC mains ground to the DC output zero-volt "ground," and John even passed along a DIY trick to do this. But for the release of the LPS-1.2, the obvious thing to do was to include a supply that is already internally shunted. [The LPS-1.2 also uses transistors with about 1/3rd the total capacitance, but really that is more of a belt-and-suspenders approach since the included UpTone-branded SMPS charger does not output any high-impedance leakage in the first place.] UpTone Audio LLC Link to comment
SWL3600 Posted April 28, 2018 Share Posted April 28, 2018 Ok thanks......so it is safe to use it with the LPS-1......no side effects? Link to comment

Geoff1954 Posted April 28, 2018 Share Posted April 28, 2018 My LPS 1.2 just arrived and I notice one odd behavior that I don't understand. I have it plugged in to a microRendu. I do not leave the power turned on over night. When I push the LPS power button it goes green. However the power lights on the microRendu do NOT light up, even if I wait a few minutes. To see the lights on the microRendu I need to unplug the LPS from the other device and plug it back in again. Then the two lights on the microRendu come on. Is this normal? Does it indicate I have done something wrong? Thanks! Link to comment
