StXII with sparkos opamps

[johhnn]

Hi And thanks for reading this thread.
Just replaced the stock muse opamps in my asus stxII soundcard with sparkos discrete opamps, and it sounds awful.
The muses are so much better.
I heard something about 100 hours burn in time is required for the sparkos, it will have to be a big improvment to warrant keeping them.
Have you heard anything about this. What is the difference in sound quality with muses compared to sparkos. Is it a subtle difference or something more profound.
Thanks!

I don't think the Sparkos are necessarily a drop in replacement into just any circuit though they "should" be able to fit into somewhere any of the Muses series work - discrete implementations of an opamp do tend to benefit from a burn-in period but it won't massively change the results.

The Muses aren't easily beaten though - I don't have any real experience with the Sparkos to give a comparison to the Muses though.

Thanks for the reply.

I have found plenty of posts comparing sparkos against burson audio opamps, but nothing concerning muses vs sparkos.

What is your opinion of the muse opamp, it is expensive but is it audiophool expensive, or genuinely high performance.

Usually when i upgrade components, if the new component is better i can hear it straight away, so am not a big fan of the burn in theory.
Might be something to it, or maybe not.

I Googled Sparkos and the first review I saw compares it with the MUSES 02....
