Roger from Rogers High Fidelity had an interesting comment somewhere about amps operating in their "sweet spot" of sort of a median power delivery, and noted as an example that very powerful amps into efficient speakers don’t get the amp into its best tone zone. Not his exact words but I get it.
@wolf_garcia I get it as well. I recently upgraded my tube integrated to a much more powerful Rogers EHF-200 MKII to power my Harbeth’s - what an idiot I am for buying such inefficient speakers:)
I now have the luxury of virtually unlimited headroom (yes, that marketing term again) and it definitely hits its sweet spot - but that is no where near its max rated output.
