Hello Simon. Welcome to AOS.
I've not heard of anybody using a Bryan amplifier for a long time. I'm assuming that is the vintage unit from the late sixties (if my memory serves me).
A photo for the Gallery section would be of interest. Older gear has a big following here and many AOS members use vintage (or partly vintage) systems.
Wives tend not to encourage HiFi collecting, but if it keeps a bloke occupied, where's the harm?
Enjoy the forum,
Geoff.
It is impossible for anything digital to sound analogue, because it isn't analogue!
