I am interested in purchasing a reel to reel. I currently have a TEAC X1000R and don't particularly like the sound, especially since I seem to be able to get better sound from my Nak MR-1. I have owned Revox, Sony, Akai, reel to reels in the past and liked the sound of the A-77's that I owned. I am considering an Otari MX-5050 BII. How does this machine sound? Are they reliable. What should a good one cost me on the used market? Any input would be appreciated friends! Thank you.
