For most applications...a quality 40 or 60w amp will suffice...and be able to drive even difficult loads to surprising levels of volume...I heard Maggies on a 40w Rega at my local dealer...and it sounded good....granted...if you want to "rock the house" or get evicted...you might need more juice...Im no expert...but even doubling your power is a marginal improvement...to really hear a gain...a factor of 3 or 4 is necessary...others will provide more technical answers...but unless you have a very large room with very inefficient speakers...I wouldnt worry about...
How much Power do speakers really use ???????
I have a debate going with a friend . How much power do the average speakers really use (not maggies etc) . He scoffs at high end amps that are rated at 100 -150 watts solid state and tubes as underpowered. I say that most of the time you are using less than 5 watts or so. And what do massvie power supplies and capacitors etc really do technically. What do you guys think? Thank You
