In Reply to: Any experience with the MA-1 III.3s driving typical low-sensitivity speakers? posted by jeffreybehr on December 15, 2017 at 16:22:41:
Two stereo amps (for biamping) and both my Butler '5150 5-channel amps will drive all 11 channels ( = 14 with the front three speakers biamped) and fills all my poweramp space.Here are the current 17 channels of amplification, with three not used. The smallish, black amp is an old Outlaw 7100.
Yes, it's a bit complicated, but with 2-channel and multichannel music and for movies, it sounds only a little short of glorious.
FWIW, I bought the first Butler TDB 5150 5-channel poweramp locally and sound unheard; it sounded plenty good enough to buy another (total cost $2475 in hand). After break-in, they sound better than I expected (and at least very good), so I got lucky with them. They use one soldered-in 6SL7 per channel as drivers.
Have just installed three lengths of Clear Day solid-silver-conductors speakercable, the Double Shotgun*, on the left, center, and right speakers, and added 8-1/4g.-stranded bass cable for biamping.
Am currently using six channels of the two Butlers to biamp the three fronts.* ClearDay speakercable uses 24g. solid-silver conductors, individually jacketed. The Shotgun version uses two conductors per pole (= 21g.) while Double Shotgun uses four conductors equaling 18g.
