Review: A worthy upgrade - I purchased a single MUSES01 and a pair of MUSES02 's to upgrade my Asus Xonar Essence STX. The sound improvement was immediate!!! Over the last few weeks the sound has been improving. After adding these Op-Amps the music became so much warmer. The sound stage width and depth improved. I put on some acoustic material with Piano and vocals. The timber of the notes was so much more realistic lacking much of the grainy harshness the original Op-Amps produced. I have a long way to go in my quest for better sound but this very small $50 x 3 purchase was well worth the investment. I listen to both Digital and Vinyl sources. Vinyl comes through a Denon 103R and Cambridge 641p with all Japanese caps installed. Of course I am using the Asus Xonar Essence STX and outputting to Bi-Amped Martin Logan Prodigy's. My room is damped and the corners treated.
Review: No Joke. more power in bass, basically open up everything while keeping things warm and detailed. - Inserted two of these into the Xonar Essense STX II, replacing the cheap 8920 and there was immediate difference...improvements in bass, soundstage...well everything basically. It tamed the highs...before I heard slight sibilance, but now it's smooth. Now I'm thinking of getting a MUSES02 for the buffer. The question remain...is it worth $50/per? Depends on how you look at it. Personally I think it is. Saved me hundreds of dollar in getting a new headphone amp. BTW I am using a Hifiman HE-560.

### ⭐⭐⭐⭐⭐ op amp of op amps
*by M***M on March 24, 2014*

I broke a couple pins on my opa2227 when I was taking it out to put this one(muses01) in my Little Dot i+ with 6zh1p-ev. After 5 minutes with the muses01 any thoughts i had about replacing the opa2227 were gone. Along with the thought of rolling in any of the other op amps I currently. have(jrc4556,ad8620,mc33078,opa2227). Its that good.
