No it will not have the Salomie circuits.
Just for clarification...
Am I right in thinking that the Salomie circuitry is a technology for analog audio inputs? In that case they would not be that important on a pre/pro that is a dedicated home theater device, as there almost all sources are digital...
Or do you have Salomie output stages as well?
What would interest me is, will the SP-4 incorporate the same kind of analog output stages as the SP-3, that is discrete and class A, all Bryston, Canada made? Will it have an analog Volume Control like the SP-3 or will the volume be handled in the digital domain?
