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.
