Just a small amp synergy report with my New Philharmonitors:
Firstwatt F7 DIY - 20 Watts class A - able to reach normal listening levels but poor dynamics, runs out of steam, bass didn't sound right. sweet treble and mids but poor pairing
Digital Amplifier Company Inline Maraschino Monoblocks with 48V power supplies: good pairing, no issues, sounds like a good class ab amp to me.
Hopefully I am done auditioning amps for a while. Right now the Maraschinos are perfect for me and my space constrained bedroom setup. I still love my odyssey kismet monoblocks, they are saved for when I redo my living room and get tower speakers the size of Exitar the celestial. (marvel comics reference)
