Shanti Dual LPS 5V/3A , 5V/1.5A

Yes it is. Our architecture is different that RPI .You can use LMS on USbridge Sig up to 512DSD with no penalties on SQ

Thanks, that's great news.

The polish distributor of Allo (Botland) is waiting for the Nirvana's CE certificate, could you send them this document?
I'd like to order the bundle Nirvana & Usbridge Signature but Botland won't order the Nirvana without the CE certificate...
 
Hello,


I received today the Nirvana and tested it right out of the box. My system is not high end but is decent. I'm using old good combo piano+kali. I was a bit skeptical about all this fuss around powering, especially that it could affect my modest audio system more than to the margin.


The result is outstanding ! I was sitting in front of the speakers, trying to understand how this could happen. Bass are less shrink in the front are much more spread into the whole space, they are more subtle. The sound is clearer, with tiny things here and there that I could not hear before. It`s really exciting. I'm going to make more testings ans try all the grounding etc...


Going to play with it now, thank you :cool:

This is the mystery..


Why a better PSU brings such improvements to SQ while they do not appear on THD+N
Can it be mass delusion ? I am very far from thinking so..


We know that THD is not SQ. What is ? OK one obvious answer is low impedance on rails especially analog . Can input rail (low) noise improve output impedance in LDOs (thats not measurable by THD data) thus improving SQ ?


Thats what we do in our free time :) we try to understand



The above being said , Rev DAC has been measured now at -116.8 THD+N (yes on RCA) with the most advanced AP on the market. Yes I know its not SQ but it shows you what level of engineering you can expect from us

The problem is that i actually can. The await-effect and anticipation is so strong that it will kick-in, to all power cable salesmen's undivided joy. But of course in some situations depending of what was used, it can be real I think.

Nulean, if you really want to know, why don't you let someone switch power units while you are out of the room and see if you can spot it?

One thing is for sure - static AP dist and noise measurements wont catch it.

I fully understand the point.


However , from a mathematical point of view , there is too much body of evidence to the contrary . Everyone (90% about) report the same effect . It is our philosophy to believe customers even without hard data . Instead we are looking at what can be beneficial and try to test our theories .


Meanwhile everyone can agree that low noise input (worst case) cannot hurt the SQ. Best case scenario they are right and our machines and theories cannot grasp or measure.

Well, most of us bying "audio" gear are humans so a common behaviour is not a complete surprise, or?

I doubt that we lack the measurement resolution - the case is that we don't measure what counts - if there is an objective difference. The one who cracks this... go for it!!

Meanwhile I'll wait for an ASR review.

Yeah its being shipped. I have requested the firmware upgrade with pop mute and found one bug on oled and asked everything to be upgraded.


India is shipping already and sent to EU stock.


I will release more firmware upgrades on Rev one that has a crazy idea on clock divider . You will increase the N (noise) to 5uV (from 3.7uV) but reduces the THD again . This time at -127 :) and especially it consists of only H2 and H3 (rest are at -140 around).

As of now, I didn't tell anything to one of my son who is learned about music listening, and he asked after two minutes of listening what was modified on the audio system... Actually, I think the difference is too big to be mistaken (and I'm struggling myself to understand how it can be, but I'm far from being a specialist like you guys). But yes, ABX, we shall organize this game.
