I've had various Nakamichi 500s since the mid 80s and was always super impressed with the quality of the recordings it made. I also have a Walkman DD30 I'm working on repairing. Main 2 channel system is McIntosh 275 and C220, heavily modded Rega P3, Lehmann Black Cube SE II Phono Preamp, PS Audio DirectStream DAC, PS Audio Powerplant, DeVore Fidelity Gibbon Super 8s. I've found lots of valuable nuggets querying these forums. Look forward to getting more great advice...
