Not all tube amps are created alike... My Bottlehead Paramount v1.1 SET monoblocks running 300B tubes had more in common with the Cherry Plus from the midrange up than they did with JWN EL84-based push-pull amp, which is more like the classic "tubey" presentation. Both the Cherry and BH amps are very linear, exceedingly quiet, and can present a holographic image, but the Cherry amps left both tube amps behind in bass linearity and extension, and macrodynamics, although the BH amps would likely do better in those departments with a tube swap and more efficient speakers than mine (~93dB/m is probably safe, mine are 91).
Comparing the Cherry Plus to the Pass Labs X150.5, which run only in Class A with my efficient speakers, I would say that the two amps are playing at the same level, just a matter of preference, with the Pass presenting a better impedance match with my pre, a touch more warmth and 3D but at the expense of dynamic snap.
Tommy's made some great amps that are definitely in the same league as great tube and Class A amps. Just makes you realize that great sound can be had regardless of topology, if you have an open mind and ears!
