Well I just came across a DC voltage regulator in the M-Scaler thread, that delivers clean power.

Might be a shortcut to just exacly what you folks are after. You could possibly use it in conjunction with the Chord PSU which is said to be RFI clean. I have no idea if the voltage regulator is RFI noisy, but whatever, here's the link.

I think that this is the one that Sbooster and MCRU uses.Not 100% sure.

I Got a Chord Qutest, and enjoy it a lot.
It is realy an amazing DAC.
Tried a powerbank as ps for the 5v, and liked the better resolution, but the Music was missing some attack, and dynamics.
But since it made a difference compared to the stock supply, I wanted to make a better ps. I already had a good expirience with MPAudio ps, and ordered a

SLS-HPULN PS With double lt 3045 regulation, and an Audio grade transformer. Using an enclosure from an Old pc. DC wire is Gotham in a 360 layout. To my ears, this is just as big a step forward Soundwise, as the Qutest was In the first place. (coming from an Arcam Irdac) Very high resolution, lots of attack, but No rough edges, If that makes sense. English is not my native language. Now back to happy listening. There is still room for powercable, and a better fuse.

I have got MCRU, SBooster, Ciunas, iFi, Uptone LPS-1.2, battery, Sean Jacobs DC4.

If I may ask, how is iFi in all this?

Hmmm I'm no electrical engineer, but while the internals of that unit certainly do look sophisticated, to me it looks more like a computer than a LPS. I'm still inclined to believe what I've learned from the former owner of Ciunas Audio. I will quote this one more time: Direct power from battery or supercap (supercapacitor) is audibly far superior than when this power is routed through a voltage regulator - all voltage regulators seem to suffer from transient response issues & create dynamic noise when providing dynamic power to devices. He went on to say that This was something I discovered many years ago & my battery PS & now supercap PS are designed in this manner. The battery packs being talked about on that thread all have voltage regulators on their outputs & are far inferior sounding. By direct, he means directly to a battery that outputs the said voltage natively, vs. any powerbank which all use a regulator to output whichever the needed voltage.

Well designed components should be insensitive to any reasonably well designed external power supply.

Hi folks,

"Truly Direct"



As for the sounds, like PP (Stock PSU) vs SET in tube topology, in short

Battery was very direct, speedy and dynamic. However vocal was leaner.

Stock still excel in the low, better layers and definition.

Please bear in mind that the stock was after an isolated transformer, kemp elektroniks SHUNT NOISE SUPPRESSOR and power wedge conditioner.

The output of four fully charged battery was 5.4V, still within the safety range. Don't use Alkaline, it may go up to 6V for four.

10000 mAh for four, lasting for 4 hours playtime Therefore someone has suggested "D" cell, at 10000 mAh each.

It's highly recommended to have isolated transformer before the digital gears, it'll lower the noise floor because there isn't any physical contact between the pri and sec wirings:

Undoubtably batteries or capacitors. Rob always said batteries are capable of huge dynamic current. Super-Capacitors too. Hence I can imagine you are hearing a significant audio improvement over stock Qutest PSU. Must be more dynamic sounding at the very least.

If you recall, I said you may have built yourself a Qutest TT. Even using the super-caps my have negated any noise from the PSU. You'd have to ask about that though.

Hilarious. Genius unquestionably, but hilarious.

Yes. when using Super capacitors or batteries, they will isolate any PSU noise. It doesn't matter how you charge them. My concern with NiMH was what happens as the voltage drops during use below 5V. I've only really considered them as a test case as I want a more permanent power supply (Super capacitors being constantly trickle charged).

Sounds too good to be true doesn't it?

I think you already have the proof as you own Hugo2 (batteries) and TT2 (Super capacitors)

Wasn't questioning you. I was agreeing with you, and enjoying that it was possible. One of those pinch yourself moments.

 

[Zzt231gr]

I see that Allo Shanti seems similar to Ciunas supercap psu.Any member having this?

I have one on order
