[The Lost Bears]

Congratulations, The Ref 5se is a truly excellent sounding preamp.

I don't think the Ref 75se would have enough power to drive your speaker properly. You could borrow a Ref 150se from an ARC dealer to see how it sounds in your system. But if you are happy with the Bryston, you might want to just keep it. Bryston makes some nice amps. Tube amps are a bit more work and expense then other tube gear. The power tubes have to be replaced every so often and the bias needs to be checked. Adding a tube CD player, DAC or phono preamp might be a better way to get more tubes in your system.

Is there any part of your system that you are unhappy with?
