Best affordable Linear Power Stage

"from Alvin at Vinshine, the DDC version is 5V 2A vs 3A for the regular 5V LPS. Similarly 15V 2A for the micro DAC."

Not really sure that I get this and (maybe I’m just cynical...) have to admit I’m a bit skeptical on it as the 3A "standard" versions would work fine with the LAIV uDDC or DAC in the 5V or 15V respective "standard" versions of the  LHY power supplies. 

On top of that a 3A version vs. a 2A version would be more "future proof" in terms of being able to be used in the future with different 5V or 15V components requiring the ability to deliver more power and would seemingly offer better value at the same price. 

@hdm  doesn’t necessarily make sense to me either but that’s what he said. Usually the device asks for a certain amperage and the supply delivers it. Doesn’t matter the max potential output. But if Alvin says it’s better then I’m going with that. I don’t know, maybe they are just labeling it to make it clear to buyers of these LAiV products and they’re really the same thing as what they’ve always had. I can test it out with a meter once it gets here.

“So received my LHY LPS for the uDDC. As advertised it’s like putting the uDDC on steroids, great product and result. I ordered this from Alvin at Vinshine Audio, this one is specifically noted on the site to be the preferred LPS for the LAIV uDDC unit.

Very pleased and only took about 5 days to get here. For anyone with a LAIV uDDC I would highly recommend giving it a try.”

I also just got the LHY LPS in and on positive phase it really rolls off the edges. Definitely sounds warmer but lots of detail lost and bass sounds hollow and weak.

On negative phase it doesn’t sound cloudy and it sounds marginally more refined. A bit lower noise floor and edges softened without losing too much detail compared to the included switching PS.

When you say it’s like it’s on steroids, what do you hear? Also, how do you have it setup? There were two cords and two outlets.

@sizzitrail84 what I’m hearing is as follows:

very big sounstage, wider; deeper and more depth.

sounds develop from a black background, fills out with weight and decays back into the background. 
 

every instrument is placed in the soundstage with great space around it and separation from the other instruments. Warmer top end with plenty of air, full accurate midrange and tight focused bottom end with punch.

it just sounds so right. I’m sure it has a lot to do with my system. 
 

System: from router, SmoothLAN into Innuos MK 3, to uDDC with LHY LPS,I2s out to Denafrips Terminator 2 12, balanced XLR via Nordost Valhalla cables to Sim Audio 700i to Focal Sopra 2’s. I feel there’s a lot of synergy with the system and the end result gives a great presentation as noted above. I’m only using one chord and out on the LHY LPS. Hope this gives a good description of what I’m hearing. I was getting a lot of this before the addition of the LPS but it kicked things up for me a major step with the addition of the LPS on the uDDC.

I have a couple of the Allo Shanti 5V LPS. Well built and reasonably priced. Chicago Electric used to sell them, but since their merger with the PiShop they no longer carry it. Audiophonics.fr has them, but I'd guess there are now tariff issues that might come into play...
