Over the years I have owned A Teac X-2000R, an Akia GX-747, 635D, A Teac A2300, A4300, 6300 and even a Technics RS-1700. I thought the Technics to be the best of them all sound wise until I got a Revox B-77 MkII recently. Mine is a High Speed 2 track version. After a good cleaning and a new pinch roller from Terry Witt, I made my first two track recording. I recorded the CD layer of Dark Side Of The Moon (SACD) direct from a Denon 2910 at 15 IPS I then went to listen to the recording on my main system (Pioneer Elite & Klipsch Legends) and wow, this the best I have ever heard open reel sound. Hard do describe how perfect it sounded as compared to my other machines. If you get a Revox in good shape, you will not be disappointed.
