Bryston warranty is transferable. For new gear you need the original sales receipt from an authorized dealer. Almost everyone who sells newer Brystons on A'Gon have this receipt. When you send amp for repair you need to send the original receipt.
Older Bryston amps (I believe 2006 and older) do not require the original sales receipt for warranty coverage. I think the SST line may fall into this group. You can check the following 2 links to get exact details,

The newer Bryton amps, the Cubed line, are supposed to be quite tubey. I previously had the SST line and I would not classify that product line as soft.
