You have several alternatives. First, you could get more efficient speakers. A 3dB increase in sensitivity is equivalent to a doubling in power amp output. Second, I like your suggestion of getting another amp, but rather than convert to mono, I suggest going with a passive biamp setup. Third, you could find someone willing to rip the amp apart and then put it back together in better sonic shape than we you started. Not impossible, but certainly not probable and possibly more costly than you think. Finally, you could dump the Nakamichi and purchase a newer, higher powered Pass designed product. It will sound better, but it is the most costly alternative. My suggestion is to try #2 and if you're still not satisfied, go to #4. At the same time, give #1 some thought.
Making Stereo amps into Mono
I have a Nakamichi PA-7, which is gathering dust. I am interested in either changing the power supply to a bigger, beefier one and or, getting another PA-7 and somehow have them both modified to make them MONOS. Is this a crazy idea or would I be better off getting real monoblocks for the price. I really like the sound of this old Pass designed amp, but I feel that there could be more power to be had. Has anyone done something like this?
