If I understand you correctly, you propose something like Lynx topology? IC amp boosted by discrete power transistors?

Not quite right for example Cary is implementing LME in SS designs. Keep in mind that most ICs means class AB verbatim.

I would say in order to get the most from home audio the key factor would be using high efficiency speakers and class A amplification. Quality of an audio source is getting very important too it must be either LP or SACD with class A output in the case.

BTW I am into HiEnd stuff for while. I was owned a lot in the past from Carver, Nakamichi up to Accuphase & power behemoths from KRELL and ended up with Wadia transport-DAC + Graaf tube gear that goes up to hundreds KHz in BW but I was literally shocked by a quality of audio it is possible to get nowadays from below hundred dollars ICs like OPA627, LME49811.

Even simpler amplification like AD8610+LM1875 using none inverting implementation properly treated by a quality trafo and audiophile grade capacitors with good backloaded horn sounds breathtaking.

I believe that OTL OCL tube gear + ESL is the cutting edge still but my opinion hear might be biased by many years of personal listening addictions.
