I have always adored the sound of my Musical Fidelity A1 (2008) version Class A integrated. But it does run HOT.
I listen with Reference 3A DeCapo I speakers, 90 db and no crossover, the midwoofer rolls off naturally so just a high pass cap on the tweeter.
If the new $1600 msrp Musical Fidelity A1 sounds as good as my 2008 version, I think you would love it.
