iFi iEMatch is Single Ended? Where is it available at a good price? Does it alter the sound?
Intrigued by your words, I opened the MF-01 and tried to install the Burson V5i I have, but it doesn't fit, it touches a screw at the back and doesn't fit. I've tried with another socket, but it's too high and doesn't close. Anyway, I have tried it slightly. My feeling is that it became a bit shiny.
I opted to use the LME49720NA and the LM4562. With the first one I liked it a lot, the sound gains in clarity and it feels more analytical, something I like. With the Muses02, it felt a bit dark and lacking in sparkle. I also tried the LM4562 and it was the one that stayed. Although the LM4562 and the LME49720NA are equivalent or almost the same, I think the LM4562 is a bit smoother, also clearer and analytical, but less harsh.
great
I think I'll try some opamp rolling myself this weekend. I might have the LM4562 definitely have the LME49720NA
Here's the video on that Burson swap
I tried it against the ZIshan DSD, JWD JVM 115, and this new micro FIWWAT H10 WS and surprisingly the little FIWWAT held it's own against the MF01. But of the 4 the MF01 came out on top for sound.
