suddenly start to wonder, what M-Audio card did you got, just check the web, and they indeed are balance audiophile card. plus, how do they sound compare to x-fi
Oooo... green tea ice cream is the best. I will buy some right now!

Did you know that some M-Audio cards come with Blackgates? Yeah kinda surprising. I have the M-Audio Audiophile 192 (of the Delta series) that I got in a trade with hydrocity here. They use the AKM DAC which is very good. I actually never heard this card, since I use its digital out to my external DAC (Zhaolu 2.5). My Zhaolu doesn't use opamps but discrete Z-transistors. The sound is very different from opamps, like comparing vacuum tubes to solid state. My current system sounds warm and intimate, and altogether pretty unique. In contrast, the modded X-Fi is like an oversamplist's dream with my K701.

The Audiophile192 has a ton of features though. You can even get 4 of them and use them all at once, like for surround sound or as speaker crossovers.

anyone can mod my xfi for a small fee and faster turning time? i cant afford to wait like 2-3 weeks without my card cause it will make my listening experience less fun...=)

regarding the power cap with 2200uF, 16V , I there a dedicated caps for audio equipments or any cap has the same function? if any cap with 2200uF, 16V is used, will this do the job in the mod ?
post #259 of 2194
Are you guys sure that the 4 22uF caps aren't necessary ? I mean,shouldn't the opamps too be given some current reserve if they are to drive headphones directly.I understand their removal if one only plans to use the card as the source(not as an amp).

Plugged in my modded card one hour ago, the sound has really opened up. Everything is more clear and the soundstage is noticeable wider.

I shorted the caps anyway despite my previous hesitations :P

Took some precaution thought.

I measured the DC output with a multimeter. it read 0.000mv all the way from starting the computer until i turned it off.
Was i supposed to play music while i measured ?

One funny thing, i then tested with some old crappy headphones and the sound was really, really muddy.

Thought it was the card that had got messed up but i dicovered it was the old headphones that were reeeeaaally crappy. Got a bit worried there hehe.

Anyway, great mod !

first i shorted those 4 caps and when turned on my pc,there was no sound in the front channel or headphones.
then i unshorted the caps and wow the sound was more clear and there is more soundstage.
can i get same results if i short others caps of surround dacs?
thanks.

huh? you shorted and unshorted the caps and the sound changed? that is strange... are you sure you shorted the right caps? i'm pretty sure it will work and produce sound if shorted correctly...
post #263 of 2194
yes,thats what i dont understand why.i also thought that shorted the wrong caps,but not i was right.

Yes, that's correct. Are you sure all four were bridged correctly? If only 3 of them are bridged, then it won't output any sound.
post #265 of 2194
all of them were bridged properly,i am very confused.
i am going to short all the caps of dacs and see what happen.

Sure, and pictures would be nice =)
post #269 of 2194
What will happen if I don't replace the power caps after changing opamp to LM4562 ?
post #270 of 2194
Codt, is the sound still noticeably better without ERS Paper? I haven't gotten ahold of any yet. If I could live without it for a bit with better sound I'd start modding .
