Next time search the forum before asking. Here's one mod http://www.head-fi.org/forum/thread/445503/cretative-x-fi-surround-5-1-modded-for-audiophile-usb-audio

Certainly I've read the thread you cite and indeed after reading it I became interested in modding a SB surround 5.1 USB, BUT that mod uses a different  opamp : OPA2365. LM4562 seems better, isn't it? . As for the DAC used, question solved. For some reason I thought D/A and A/D were integrated in the same chip, but it was a wrong assumption. CS5345 is A/D and CS4361 operates D/A conversion. I wonder if the DAC can be swapped  by a better one too.

Oh I see. Well, the DAC is quite unique, with a single 5V supply, I don't think you could swap it though. But it wasnt that bad, try to Google the name of the DAC, you'll surprised

 

EDIT: Don't use National opamp, it needs rail-to-rail, or something. Check out my post at opamp thread in DIY subforum

Also the OP said his mod was intended for use with IEMs but I want to plug full sized headphones , a pair of AKG K601 to be more precise. I don't know if capacitors should be different or what.

I wouldn't let the THD values get you down.  There are many devices that have higher THD ratings but still sound great.  These devices would easily surpass devices with lower THD values also.  It is up to you but I wouldn't worry aslong as it sounds the way you want.

Those THD values are still ******* small.

hi

is some1 selling hotroded xfi xtreme music?

post #2093 of 2194

Would it be worth trying this on my Auzen Prelude? Would the Prelude do better than my Mamba as an amp + DAC for my ES10 on the computer?

guys, i have elite pro & cavalli kan kumisa III 

so the question is - where i can get a pure line out on it?

i want connect cumisa directly to sound card without amp.

someone know? 

where i can solder my wire on sound card to get a pure line out?

post #2096 of 2194

I just wanted to thank everyone, basically i've never soldered in my life but i am big on music and after reading this thread and using everyones advice i modded my x fi music card , the first attempt was a failer, trying to take off the coupling caps i overheated the board and a lil trace popped up and that was the end of that, since realizing i didnt have to take them out to short them i bought a new card i still took off the caps but just cut the legs down and soldered wire on the back of the board, yay, the power cap i had trouble with, so i used a 1mm drill bit on it and installed a 2200uf 16v panasonic FC, then today i received my opamp the from canada and completed the mod, WOW what a difference, on rock type stuff its ok but when you play electronic music with lots of different basses and detail its out of this world, so thats what decent music sounds like.....thanks CODT and CO " class="bbcode_smiley" height="1" src="http://files.head-fi.org/images/smilies//smily_headphones1.gif" title=":)" width="1" />

has anyone been able to compare a hotrodded x-fi with the auzentech prelude? i'm looking into getting a sound card (current source = motherboard -_-) and debating if i should get an x-fi (elite pro?) and hotrod it.

post #2098 of 2194

Does any one know where the muting transistor is on the x fi extreme music is so i can remove it, thanks

post #2099 of 2194

I lost the pictures of the finished job, but you can bypass the muting circuit by removing the 4 transistors and wiring as described below
