I see that you are using the Nakamichi 682 ZX. Very excellent cassette deck. Clearly cassette still works very well. In my opinion it blows many digtal formats
(such as iPod,MP3, and music downloads) out of the water.
Like the turntable, the cassette (such as Nakamichi) follows the music to a fault. I find the analog formats to be very natural.
May you get many years of service from your Nakamichi and the rest of your system.
