Shocked. Need Opinions. How muck power do I need?


I’m moving so of my sound gear around. As a temporary measure, I set up my little Cambridge EVO 75 in my main system. Driving my Dali Mentor 6s in a large room (36x36). Speakers are 9 feet apart and seat is 10 feet from speakers. This 75 water replaced my much more powerful monoblocks. To my shock, the amp drove these speakers just fine. The bass was a little weaker, but perfectly acceptable.  Here’s what I want to know— if 75 watts are enough, will 40 watts do? I’m talking all solid state. What say you?

one of the rare threads in which everyone seems to be making good points. my own experience, which matches other posters', is that high current delivery is by far the most critical factor--even with demanding speakers like dynaudio i've heard 50w pass amps outperform amps with much more wattage.

@erik_squires, i will track down the pass article. i would add parasound as an amp which does well with challenging loads--during my brief forays with 83db planars my 125w hca1000 was surprisingly capable.
