Speakers for Bryson 4B sst2

That amp has enough power to drive just about anything.

Magnepan 20.7

I own the Bryston Bp-26 Bryston BP1.5 phono, and Bryston 4B-SST²
I use Magnepan 3.6 speakers.
If I had $15K to spend no question I would jump up to a pair of 20.7 magnepans.
Spend some of the leftover cash on a Furman top of the line 20 amp powerfactor conditioner.

I agree.. The 4B can pretty much drive anything..
