There is a reason why audiophiles are heading back toward integrated amps and receivers.
The sales pitch went...
Receivers
Integrated amps
Preamp & amp
Preamp & mono blocks
Sadly this is an upsell tactic more than a sound quality one, most of the time. Now that reviewer guilt selling has run it's course a lot of HEA folks are going back to Integrated Amps as their amp, and simpler speaker designing with less crossover work.
Your also seeing One Source systems coming back into play among the purist.
