What after Aleph 3, need more juice?

W/P's and a pair of Pass Labs Aleph 2 monos are a seriously sweet, but surprisingly dynamic combo, even in a large room. Aleph 2s sold for $6800/pr new, and you should be able to find a good used pr for half of that.

You can get another Aleph 3 for biamp or bridging.
I always prefere bi-amp.
Another option is Plinius SA100 used.

Try a Pass Labs-X-250 for around 3K or an X-350 for around 4k. It will make those puppies sing.

Unfortunately, you cannot bridge the Aleph 3's (per info from Pass Labs).
