Expensive indeed. I look forward to seeing both on the rack. What is the output per channel?

I alos like to keep it in original state if possible. But I have one piece that is really kinda rusty.... a problem in this humid environment.

Have you listened to other 845 driven amps before, like the nagra VPA ? Wonder how those measure up.

My new additon, a pair of RCA auto tranformers MI-9472-A, that allows me to match my amplifiers with speakers of difference impedance. I must say I like the sound alot better than the UTC LS-33 which I was using.

Borrowed some photos from Oswalds Mill; actually bought the transformers from him.
