Saki70:
I have been using the Prima Luna Prologue Two happily for the past year and a half. Admittedly, auto-biasing was one of the things that made me go with the P2, as I wanted a no fuss tube amplifier with possibly some tube rolling as the only tweak that I would perform. Note: The stock tubes are pretty good, but I replaced them anyway. I replaced the stock KT 88's with Svetlana (SED) KT88's; the 12 AX7's with NOS Sylvania; and the 12AU7's with NOS Mullard CV4003.
I can't say enough positive things about the P2. See my review of the P2
here . In fact I liked the P2 so much that I replaced a very good power amplifier in my other system to put in a Prologue 5. I use the P2 in a manner similar to yours ... in a small room and nearfield. This system sees more use than any other system. I didn't audition any other tube amps. I had dealt with Kevin Deal before, trusted him, and went with the P2.
For a good overview of biasing and what is involved
here is a good site .
As for speakers, I am currently using Omega Super 3 (single driver), but would also recommend the NHT Classic line (Two or Three).
