Congrats on some really good speakers..Since they are not really large speakers with DEEP bass,I assume your room isn’t real big & you don’t listen at head banger levels...
If I were you,I wouldn’t worry about your amp until you have several hundred hours run in time on those drivers..Once they are run in well,then do your critical listening..My opinion is high power is over rated unless you listen LOUD in a large room..WhatHiFI says:
"We use a range of speakers from Dali’s lively Zensor 3s and Dynaudio’s Emit M20s right the way to the ATC SCM11s and PMC Twenty 26s and at no point does the Rega fail to shine.
Of course a power output of 72W per channel into 8ohms isn’t enough to make the floor shake in really large rooms, but we think this amplifier is capable of decent levels in most set-ups.
It's as happy picking out finer threads of detail in the convoluted sections of Hans Zimmer's Mountains from the Interstellar soundtrack – often the first to be overlooked by less scrupulous amps – as it is unveiling variation in hammering electrics in Band of Horses' NW Apt.
We are pleased with the resolution on offer, and at no time is there a sense the Elex-R is overlooking subtleties for the benefit of the bigger picture.
We notice, again, that this amplifier is terrific at communicating the drama of the music. It has us hooked from the first note, right to the end of the piece."
