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..

Agreed, that amp will drive any consumer rated speaker available in this galaxy. You need to find another conditional filter. with your budget you should audition everything you can to find the sound that suits you,

I have the predecessors of your stuff (4b sst and bp-20)and going strong now for 9 years or so.

very good amp and very large array of speakers it could drive.
