Amp experience

kosst_amojan - I know how logs work, what I don't know is whether ktz03110 does.   Consider this, the 10*log(10) of 20 is 13 dB, 10*log(10) of 200 is 23 dB.   That an increase of 10:1 in power. 

Another way to look at it is if music is running 20W at one point in time and the next point in time music demands 200W, that is still a 10:1 change in power that the amplifier has to produce. I purposely used those numbers so I could say a 10:1 power change.  I never said a 180 Watts is 10dB. 

If I had a sound system that only used 1W typical, I wouldn't be looking at a 200W amp, as I mentioned above, as well as the reasons you stated.

My point was that very few people use anything like 20 watts. Average volume at average distance from average sensitivity speakers required more like 2 or 3 watts. I honestly don't know why people think they need 400+ watts unless they're driving very difficult speakers and/or filling a huge volume of space. 

Or listening to Classical music .

Yeah..... That's the typical claim.... Like nothing else even comes close..... Which is demonstable false. 

I bought an OHM 5000 in 2012 and had a Bryston 4bsst 300 watt. The sound was less dynamic than I was accustomed to hearing. I went up to a 14bsst 600 watt and it was like taking a v6 out of a Cadillac and putting a v12 in. Varoom!. Dynamic slam, headroom and bass impact came back and beyond. The speaker came alive.
