How does your Picollo and O2 compare to your 12A and also paired with your X3ii?
I also see you have sold your Shure SE215 which someone recommended to me and I would be interested to get your views on it?
Thanks LM
Have been on a course the last little while and am yet to do any serious comparing of the three amps. O2 is a very recent addition to my collection, so haven't really had much chance to give it a workout. My brief impressions are that Picollo is a touch warmer and less powerful than the E12A, and O2 a bit less clean. Only the E12A has bass boost. I did touch on the pairing of the X3ii with E12A and Picollo in my X3ii review (see link in my sig).
I sold the SE215 after getting the RHA MA750. The SE215, to my ears, suffered from too bloated bass and not enough treble. The MA750 still has an excellent bass signature, but better defined, clearer mids and highs. When I got them the SE215s got relegated to bottom of my heap, so I let them go.
