3 channel amp to compliment Pass Aleph 30 for HT

Good question. Given the wattage, you might even consider some lower power tube monoblocks to give you another 3 channels. Alternatively, perhaps a Monarchy Audio SM-70 (25watts per side class A) for the 2 rear channels, leaving you the center channel to fill. The Monarchy can also be bridged to mono, so a second one could give you the center channel, matched of course, but at higher wattage (can't recall, maybe 45-50 watts mono). That might present a problem with appropriate setting of volume levels, but a Rothwell inline attenuator could be used to drop the volume 10db on the center channel bridged monoblock. You'd want to look at the decibel levels to see if that suggestion holds any water. But anyway, you could get creative if you don't find a 3-channel amp that's a perfect match, that's my message I guess.

I would recommend buying more Pass Labs Aleph XX amps. Anything else will be a compromise. Those Pass Labs Aleph 60 monos just sold, so you missed those. Add 60's to the front and move the 30's to the rear. 6ch is not a bad idea either in case you want to move up to 6.1 later.

If you really want a 3ch amp there is a Mccormack DNA-HT1 available. But, for 500 bucks more you could have a stack of Pass amps instead.

If you really don't care much about muti-channel music or the quality of surround sound than there are many more choices. Match your amps and your speakers for the best results.

REL subs seem to be a big favorite when it comes to musical subs. You can spend hours reading up on these in the forums.

I have considered two more Aleph 30s, but it seemed like overkill for the rears. Maybe the recommendation of 3 Monarchy would be the best bet. But at ther cost 2 more Aleph 30 seems more practical, it just seems like over kill for the rears.

I was thinking the REL sub would give the sound I am looking for in the bass region especially since the Aleph is so high quality for my R&L channel.
