Class A SS vs. Class A/B SS


I am looking for a new amp/integrated for my Adagios (89db), I currently run KT88/6sn7 tube monos (50w), i want to buy a SS setup for when I want to just fire up an play (my vintage tubes take a while to warm up), I am torn between a high quality A/B design (eg. Bryston 4bsst, Pass, even Class D Bel Canto, W4S or MF integrated) or a true Class A amp like the 30w Pass 30.5 or a Class A Luxman or Accuphase etc. I am kinda leaning toward integrated for the convenience. I listen to primarily vinyl. Please help I know much less wattage is required for class A but how much is enough?

Though not yet set up to play -- that applies to the whole "new" system I have been assembling from the ground up -- I have a pair of the Adagios here. My expected-to-be #1 amp currently in residence is a Cy Brenneman 15+ watt SEPentode-follower (KT-88... KT-120?) Cavalier Plus. Adagio designer Robert Lee assured me that I would have sufficient power for my personal requirements -- ecclectic tastes, infrequent LOUD sessions.

Everything being "new", I wanted options, including higher power tube (got 'em) and solid state. FWIW (still expecting to be first and foremost in the tube camp -- though not dogmatically), I bought a Pass Aleph 30 and a new Illinois Rawson (sort of FW F5 on steroids) from Tim here on
Audiogon. Hard to beat this combo for the price, I expect. I do not anticipate being short of steam.

Also note that Paul Speltz's Zero autoformers can be used to deliver more CURRENT grunt from these amps -- yes, you can get more EFFECTIVE wattage out of these into some loudspeakers via this route. Not a "free lunch" -- but it may seem that way in some cases.
