Yeah, quite interesting. I also know a lot of people who has changed from NE553x to expensive "racing op-amps", and believed that the sound was improved greatly. But, every time they have tried to change back, they descover even bigger improvements .

You must be carefull not to cheat yourself in believing, that these "racing op-amps" sounds better, just because you know they have better specs and cost much more.
I guess there must be a reason, that more than 99% of the music you listen to, is made on gear build around NE553x's.

NE553x is extremely neutral, where many of the expensive op-amps tend to have their own sound. Again, this can be very impressing at first. But normally people find it hard to live with these "racing op-amps" over time.

It depends wich OPA replace the 5534(2).

I recomanded, try AD9631 or ADA4899-1, but not as direct replacement on previous PCB.
You must conect it on own PCB with good power supply decouplung and Resistor (50 - 100R) placed direct on +in and out pin .

Hurtig,
I always suspected the same results as you have described. Actually the first thing that was apparent was an increase in dynamics and a deeper and wider soundstage. I cannot find any shortcomings whatsoever, it really shocked me. You should give it a try, you will be very surprised, as I was.

Bill

Hi bwaslo

the crackles came from an old Dell notebook from 2002 with an USB2 pc-card converter. With my new PC (E6700) and Vista there are no crackles anymore! But the notebook is in the living room with my hifi gear.

At the moment the Emu 0404 USB is wired by optical cable to my DVD player. The sound quality is almost good but I think there is a lot more to get out of it.

Has anyone of you already modded a Emu 0404 USB? It is all tiny SMD stuff with less than 1mm distance of the chip legs!

Opamp need not to be expensive, the excellent sounding lm4562 is fairly cheap.

I concur with Bill that direct tranny out sounds very good too. I tried it on the ak4393 only.

I'm feeling a bit lazy tonight, so maybe someone can tell me if the 93 can be desoldered and the 96 soldered in in it's place in a DCX2496? Without any other mods that is.
Cheers

I never listened to the LM4562, but I believe that a few people mentioned the sound of it to be flat and sleepy.

.
Which opamps did you listen to? The LM4562 seems to be one of the favorites of modifiers right now.
