As it turns out, my amp was one of the earlier units that were wired a bit differently, so the instructions did not match this amp how to properly bridge it into one channel. I was already working a deal with a guy so I went through with the sale. However right before I shipped it off, I did successfully bridge the amp and it probably would have been just enough power for my center channel.
My experiences has brought me to the conclusion that up until about 20 -30 watts, every +3db in amplifier gain really shows up on the output. Past that, the differences in power are not even close. That is, comparing with equivalent efficiently speakers. When Steve D. says the Torii MK II is a pretty ballsy 25 watt per channel amplifier, it’s not marketing hype, it is ballsy. Going from 6 to 12 watts on the SE34I.3 made a huge difference. Going from my 60 watt KT-88 amp to my 25 watt Torii shows little difference in needed head room or listing level. My speakers are rated 102dB @ 2.83 volts/1 meter. However I think that can be deceiving because I have heard speakers rated less, that when fed equivalent power, sound as loud. I have no clue how they rate them rather it be pink noise, 1 khz, etc. but when Steve talks about the speakers impedance curve it make perfect sense. Some say that my series of Klipsch don’t come alive until they have a couple hundred watts at their disposal. I will say that they did not come alive with this amp at 6 watts per channel, they do with my Torii, but when bridged with my center channel that has about the same efficiency this amp really started to wake it up. I wish that I would have had the time to see what this amp sounded like bridged into one of my Left or Right speakers. Two of these bridged for a two channel set up might be something special with the right speakers. I know the gentlemen that bought this from me is absolutely loving it.
