Is there such a thing as too much power?

As far as the car analogy goes, My 350 hp supercharged S2000, is far less tractable, due to requiring 7000-9000 engine speed, than are most turbo cars, such as my 15 psi 280 hp MR2.  This autocross suspended MR2 and most Porsches are great without attracting attention with a 9200 rpm amplifier terrorizing the neighbors.

     Forty years ago, When I "downgraded" from a Phase Linear 400 to a 100 wpc Audire, it was a major improvement, with subsequent improvements since, pretty much unrelated to power.     However!  The best home system I ever heard was a pair of actual B&W Nautilus speakers, which require a highly damped 350 wpc amp for each if its eight drivers.  It was exactly powerful enough.  This owner used Mark Levinson, back in the day.  B&W had their Classe division make amps for these still extant. special order speakers.  I wish Audire could power them, assuming Julius (Siksnius) could still create his magic, plus he preferred 100 wpc amps and speakers that could use them.  It is not all about power.
