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).

I crossed that bridge three years ago, when my a 3 simply couldn't push the 4 ohm woofers in my new Parsifal Encores.
A pair of Aleph 2 monos continues to provide incredible satisfaction, especially well served by an Aleph P. I'm hanging them from floor joists under each speaker, with 8' ribbons of SPM flowing back up through the baseboards. Quite stealthy, which was VERY important to Ellen....
Pair of the Aleph 2 continue to sell under $3k. Such a deal!
