I’ve read about the benefits of integrateds (have only used separates since my first integrated, which is still in use.)
Came back from monoblocks for convenience. Of most importance beyond usefulness to me is the feature set - RC everything (balance, mono, tape loop, etc.), processor loop(s), balanced in/out, at least 5 inputs, etc.
If I must have tube sound a myriad of buffers get me close enough, love my FOZ SSX. Much better Fosgate sound than the cheap SS unit that it replaced.
I do enjoy two tube headphone amps, both have SS output stages.
Most of the time I listen to ESLs through RC DACs feeding Class D SS power.
I can play HiFi
music 24/7 @ under 20 watts out of the wall.
