I believe my Pass X250.8 pushes about 12% class A and I never had any needs to out of it. About 30W is plenty as long it is backed up with huge power supply and enormous banks of capacitors
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?

@swede58 well thats even better, meaning that 20W does the job |
@livinon2wheels while I agree with you that Amp should be about double power rating than your speakers MAX Contin. power, lately I started to think that if your speakers can deliver maximum power without the distortions and sound is way too loud to sit and listen to it than you got correctly working system. My 250W amp is pushing enough power and staying in class A, that I have no desire to ever turn it up. My speakers are rated 300W max but I think 50W class A amp will do Just fine. So it's not a power output that matters it's the current levels that count and power banks size. |
@livinon2wheels lets get something straight. A. My amp is Pass X250.8 so by definition is not class A amp it is A/AB class amp that runs first 15-20W in class A and it working temp regardless of class operation is 119F. Its not the coolest running amp but its far cry from Pure Class A working temp. B. It is not a STASI circuit so it does not stay on 24/7 and idling at 900W, there for my electric bills are not so bad up to date $76.92 was the highest bill since I got the amp running and opposite to my Threshold S550e it consumes less power at idle. C. Yes it s a hobby so by definition you have to sponsor it, now, do you buy records ? CD's? if yes you know your choices are what makes that hobby yours... so are payments and all cost associated, If you are not ready to pay up, don't get in to it, like every hobby that one gets expensive as well.
The sound quality is your reward, take it or live it... |
@swede58 yes, JBL 4367 does the trick at 94db 8ohm and they are set at neutral setting for crossover loads |
@swede58 well that those 16 watts, is just enough.... :-) |
