I have a Denon DP 47F that I bought new about 30 years ago. It has functioned flawlessly - I've never had a problem with it. I'm running a Hana SL cartridge through a Krell phono preamp. I replaced a Shure V15-V with the Hana and I very happy with the sound. (I got a surprisingly high price for the Shure. They are very sought after).
Just for fun I have compared a few good LP pressings to their CD counterparts to hear the differences. I'm running a Jay's Audio CD3 Mk III transport through a Berkeley Audio Alpha Reference 2 DAC and the Berkeley USB interface. It's amazing how similar the CD and LP sounds. If there's anything wrong with the turntable it should show up on this comparison. I've also done this with a few SACDs (Marantz SA Ruby) and their audiophile LP counterparts. I can tell you that one doesn't blow away the other. They both sound excellent with some fairly small plusses and minuses for each.
I've thought about upgrading this turntable but I just love it and I'm not sure I would get significantly better sound even if I spent 5 figures. For now I'm just going to hang on to it and listen happily.
