Main living room - Peachtree Decco 2 (MOSFET) - 40 wpc @ 8 ohms
Office - Monarchy SM 70 (MOSFET/Class A) - 25 wpc @ 8ohms
Main system - Emotiva UPA-200 (Class A/B) - 125 wpc @ 8 ohms

No flaming if these figures aren't exact...I think that's right though...too lazy to look it up, lol.
 
Kenwood KR 850 75 wpc @8 ohms .01 THD 20 Hz to 20 kHz

Kenwood KR 4600 30 wpc @ 8 ohms .5 THD 20 Hz to 50 kHz

Sony HT 100 wpc

I use Polk TSx 110s (90db) for both of the vintage systems and am 100% happy.

McIntosh 4100 receiver. I use it with 4 ohm speakers(AR3) where it pushes out at least 100 watts .

The Mac has since been replaced. I now split duty with this(about 22-25 watts)

15WPC JLH 1969 Hood integrated
45WPC Oldchen KT88-K3 integrated
80WPC Tascam PA-R100 AVR
100WPC Quad 405 copy power amp
140WPC darTZeel NHB-108B copy power amp

I won't bother listing the various little S.M.S.L class d amps. Only the AD18 see's any kind of regular use.
 
Let's see, they are: 4, 17, 18, 20, 30, 50, 125, 140, 180

My system used to be in a much larger room, 600sf. Now I've downsized to 230sf. And I sit closer, only 6' now. Between this and listening at a bit lower volumes, I find that I can run on much less power.
 
Questions on power. I had a CJ MV75 75 Watts per channel. I had a dynaco st-70 35 Watts per channel. Now I have a Single ended ultralinear amp (diy with modifications) using 1 6550 per channel. I get around 9 watts measured using an 8 ohm dummy load. I can’t even max out the amp when my speakers are connected.

I understand the idea that higher power amps have more “headroom” for transients. But my 9watt amp appears to be more than enough. My speakers are very effiectient 98db


Help me understand why / how lower power amps can sound better than higher power amps. I have heard this with low power 300b amps as well.
