Hello. Thought I would re-start this thread, rather than start something new.
My good ol' Audire preamp has given up the ghost and I think a Bryson BP20 or BP25 would continue and maybe improve on the the warm, crystal clear sound of my Audire.
I definitely will want to have a BP20 or BP25 - with the MPS-1 power supply ultimately incorporated. Somehow I get the idea from reading here, that not all BP20s/ BP25s are capable of accepting the MSP-1 upgrade if the Preamp originally came with the BP-PSR power supply. Is that correct, or will a MPS-1 work with any/all BP20s and BP25s?
