x-fi xtrememusic vs m-audio audiophile 24/96 - Page 3

post #31 of 33
The 'dullness' some people hear in the M-Audio Audiophile 24/96 is probably due to the crummy JRC5532 opamp driving the output.

If you can do minor surface mount rework, it's pretty easy to replace that 5532 with something better.

I used an ad8066, and I'm very pleased with the results. Plenty of sparkle. I'm sure other good chips that work on relatively low voltages like an ad8620 or lme49720/lm4562 would give good results as well but the only other dual so-8 parts i have are opa2132u, and I'm tired of that sound.

opa2107u might not work so well - that chip loves voltage and there just isn't much of it on a sound card.

Frankly it would even be vastly better with a jrc2068 - that's the stock chip on the emu 0404 - but if you're going to desolder an smt part you may as well not replace it with a 50 cent part when a better part is just a few dollars more.

Also replaced the output caps with silmic 2's while i had the soldering iron hot anyway.

how crummy exactly?
I was told on a DIY forum that a properly implemented NE5532(same as JRC?) could sound just as fine as a LM4562 if the rest of the IC was well balanced towards it.

it's not as bad as a a JRC4580, is it?

can this soundcard drive 600Ω cans? I had many problem w/ the cd3k(32Ω/104dB), the 770Pro/250 is very better driven...the cd3k had a major lack of bass and clarity, but it's also known to require expensive amps

Just because you get loud enough "sound" out of a soundcard, doesnt mean it is properly driving them. not to mention you're source is smack dab in the middle of a big EMI emitting machine....
you're nailing it I think ?!

that's my Audiophile USB :


it seems that it's got one JRC5532 for the lineout, and 3 of them for the headphones out.

the cd3k sounded very thin and weak on the lineout(just like it did on the X-Fi Xtreme Music), and much louder but bass shy and not very clear in the headphones out.

the 770pro/250 sounds perfectly fine on the headphones out....and maybe better on the lineout ?! need to run more tests..

from what these guys say, the higher the impedance the easier it actually is to drive

Is it going to really matter the dac of the soundcard , opamps etc ?

Thanks for your inputs
I have the same headphones as you, and I use them mostly for gaming with a x-fi xtremegamer (which is not the basic crappy version you were considering).

Now, I can tell with no doubts that an envy24ht based card such as my new Infrasonic Quartet sounds much, much better.
I recommend it wholeheartedly.
