It's some what apples and oranges.
Sure Axiom makes Bryston but it is to Mr. Tanners specs.
Our drivers have 11/2 inch coils the brystons have 2 inches.
We get 90 to 95Db the same model of Bryston has 100Db plus.
Our units need shipping the Bryston doesn't. So weight of those units is not an issue they can add more Baffling and such.
For greater SPL etc.

Have spent sometime watching the tube regarding this.
It is a fantastic partnership we are all benefitting from their combined experience in all aspects of audio is pretty cool.
