I understand that. I am just curious to get some reading. Well then, something more realistic : What would you upgrade a Muses02 with ?

Hi everyone. Is there a page in this topic or somewhere else on headfi where we could fine a side-by-side review of many opamp ? I am thinking OPA6X7, MUSES0X, LME49XXX, AD797 and maybe some V5/5i/6 and other discrete product, all in one go ?

Just in case someone might be interest I have a A10 pot that I would be willing to send to anyone (preferably in the EU) with a non-Muse edition of this DAC. I previously had a non-Muse edition that had some imbalance because of the B10 pot. I scavenged everything I could from my dead Muse...

Thanks for your answer. I'm lucky to have no hum on mine. For the rest, guess I'll jump on my probes and test the rails. Saying free of mod was not perfectly exact since I have AD797BR (tuned following the datasheet) as buffer aop. I might try some V5i as well for I have bass-shy headphones...

Hi raoultrifan, From all these mods, which one would your recommend the most ? I have the Muse Edition, free of mod, but I'm interested in trying, provided there is an audible benefit. Worth it to buy some V5 or V5i ? Regards, wanted.

The stock muses 8920 look to be good, so i don't know if try some other amp will improve the sound quality to you. But, if you want to test some good amp, start with AD797BR (take a goodlook at the datasheet, there are capacitors to add, between 2-6 and 6-8 if i remember).

A Xonar ST with good amp  like 2xLME49720HA or 4xAD797BR for exemple (check Xonar STX modding impression thread) don't have to be changed for some Audio-GD.  You can also change the TCXO, to close the debate and not spend hundreds of dollars for no gain.

After reading >200 pages on the Essence One thread and and more pages on the AOP one, i mixed that with what i have already tested. The AOP that are a must-try :  - LME49720HA or LME49710HA x2, not NA nor MA, metal can TO-99 version - AD797BR (Tricky to use) - LT1363CS8  - Muses01 & 02  ...

I'll try this, thanks.

  So you are suggesting that i order a bunch of b10k and hope one will be balanced ?

Hi guys. Serious problem unsolved here : Can someone post a link to a replacement pot to solve the unbalance problem of the B10K ?  As some others, this is draving me crazy ! 

You can cut the 8 legs to make it shorter without any problem. Look at google image for LME49720HA and you will see one very short cutted on a STX socket.

Come on, cut it ^^

You can just bend them a little yes.

Powahlam   -> Yes just 2x LME49720HA ( HA do is important! ) and bend them a bit to make them fit, you can google image this  ;)   superfedya -> Vanguard TCXO from ebay, about 30€.  There is only 1 reference when i search it ...
