Actually a lot of opamps out there which are compatible, you can try them all, but you need money as well...

yea..some opamp are reali expensive..

True, but well, I'm not too keen on changing opamp again. But well, I try my luck on this new one, hope it will be the last one that I changed. I requested for some sample of LT1364 from Linear too, but I think thats gonna be awhile before it arrives

sure this is the last one or not? poisons all around

EDITED

I still don't know. Actually I really wanted to try AD8599 but Farnell won't accept credit card, RS don't sell them either If this super secret opamp sounds nice, then I'll stick to it. If not there is LT1364.

I changed opamp few days ago, although I don't believe opamp burn-in I do hear sonic difference now, it started to sound warmer and mellow slightly from the day I solder it in

I'm sure there was something wrong in your latest results...the frequency response definitely won't exceed +-0.5dB...

Added on June 16, 2008, 9:20 pmwhy not you use Maybank2U for Farnell purchase?

Since you desolder/solder the opamp repeatedly, why not you just solder 3 different opamps in the board so that you can compare them directly...i plan to do so, at least 2 different opamps...

I don't have Maybank account unfortunately

Good idea, but since I bypass the muting on primary, its not fair that the other channel still have it. I'm planning to remove opamp on other channel leaving clean supply to front channel

you can bypass those muting transistor as well...

may i know which X-Fi you using? non-Elite Pro won't show those excellent results...

X-Fi XtremeMusic first batch. I noticed there were few inconsistencies regarding RMAA test results...
I start to feel weird....

are you using line-in for recording or wave?

can you post you graph of frequency response, noise level and dynamic range?

EDIT: i highly doubted that you are using wave recording rather than line-in...impossible XtremeMusic can reach -106dB noise level and dynamic range for loop back test...

"what u hear" stream....

men, DSP internal loopback test is useless...see my edited post above..

Those muting tranny is different, if you have the pinouts let me know

I'll rerun the test with real recording results.. stay tune.

no, we no need to care about the pinout of those transistor...just solder the cable before those transistor and after SMD output resistor is done...

EDIT: OK, for those transistor in that surround channel, you will see N20+ printed on top...to bypass, just short the upper pin left and upper pin right...

I guess my previous results are useless now.

Alright thanks for the info, currently I have no intention of doing so

Weird, the LME49720 becomes more and more listenable now, Katie Melua never sounded this good before I don't think I need to change the opamp again if this continue
