MAKING A DECENT HI-FI POWER SUPPLY FOR XONAR ESSENCE

[GWorlDofSPACE]

Yes, the whole package is good! If you have a clean and qualitative source then you
can see how good the essence really is!!! Its night and day!!!
I just figured out what was wrong whit the 5V supply, the essence needs 1,5A of
currant and not 680mA!!!! Kingwa said my PSU cant supply 2A of currant so I must replace some componets!! But he will offer a new PSU09 and this one will be able to supply 2-5A!!! The bottom line is I will work on my PSU to achieve the 2A mark and will cut the dirty PC supply!!!

adding exclamation marks everywhere won't change a damn thing!!!!!

how about some RMAA results w/ your stock ATX PSU(model please?), and w/ the new external PSU please? "better" and "good" are quite subjective...as you will agree, nothing can be more easily fooled than the human brain

I've got a high grade ATX PSU(voltages couldn't get any less ripple), I've kept the STX on its own rail...and I can't hear the "dirty" noise you're mentioning

 

[GWorlDofSPACE]

Do not be offensive, you all are intelligent people and know that everything is subjective.
The RMAA test yes maybe will be a good benchmark!
For my taste its better what i have experiencing true the PSU of kingwa!!! But this is not a complete review because I can run it on 5V too. So I have to wait until I have the complete package running!

 

[GWorlDofSPACE]

(I cant run it on 5V too)

I have not mentioned any dirty noise but the colouration of the power supply from ATX PSU!!! I think there are many factors not only the ripple!

 

[leeperry]

"colouration of the power supply"? I hope for you that Gregorio won't see this thread

I talked about that w/ a friend of mine who's an EE, he told me that most "serious" audio equipment will have caps and stuff to stabilize the electric input...I believe the STX has a bunch of SANYO caps.

anyway, I guess you can't quite measure "the colouration of the power supply!!!!", so what matters in the end is that you like it better like this

 

[GWorlDofSPACE]

Of course the essence has filtering stuff!
leeperry yes in the end its your subjective feeling that matters!!! I see where all this is going! I will just say buy or make a PSU and then you will hear the difference for better or not!!!
I like dynamics and clarity of music and when I connected the half of kingwa PSU to the card it really was an improvement. The instruments played whit ATX PSU are more would say feeling flat. Whit kingwa PSU everything expended in freq. or they are more details in the music! (THIS IS MY PERSONAL OPINION)

 

[leeperry]

but did you change the op-amps too? coz the 2114D are really lousy..

 

[GWorlDofSPACE]

Yes. I have 3x burson dual opamps!

 

[leeperry]

haha cool! can the card output enough power for these monsters?

and how is the soundstage/distortion compared to the 49720?

 

[GWorlDofSPACE]

Yes it does! Instead of 150mA on 12V+ are the supply now 400-500mA. The opamps are working perfect! I also have tried 49720s. They are not bad!

 

[leeperry]

2114D>49720HA is night and day....distortion becomes inaudible and the SS becomes huge! how are these on the burson? I understand they'd be more distorted but give more details? and how is the SS then?

 

[GWorlDofSPACE]

Please this I a thread for PSU! We can talk about it on sneak prev thread if you want!
Their are more details and you hear a bigger sound stage. Every instrument has more substance. The sound is more dynamic and natural sounding. What do you mean SS?

 

[eugenius]

How much would you want to get such a thing:

And mod it to an uber-essence stx with external PSU, rfi shielding, USB hub, USB to Lan, optical already included in the box?

hey, yo, what's your computer PSU (brand and model)? Saying that the audio-gd is night and day compared to your PSU means not too much for us if you don't tell us what's your computer PSU.

What does make a PSU better than another in terms of final sound quality out of a DAC and AMP? Wouldn't it exist a computer PSU which is as good as the audio-gd PSU? As far as I know, the good computer PSUs output one of the cleanest and stable DC signal for electronics. (e.g., http://www.corsair.com/products/hx/default.aspx)
