Step up from Nakamichi 582 tape deck?

Well, 680zx is a warm sounding machine and has best bass of most cassette decks. If you're OK with auto record calibration then yes unless you find a screaming deal on a ZX-7/9 or 1000zxl. To my ears ZX-7 is a great recorder and a Playback machine but  it doesn't have the warmth of the 680. 

I went with the 680zx although he also had a zx9 for sale but that was a LOT more money, much more than I am prepared to spend on a cassette deck.
We will see when it shows up in a back to back comparison with my 582.

Uber, did you receive the 680? How does it sound?

Not yet, I missed the Fedex truck yesterday and it needing signing for.
Now I am away all next week so I imagine it will either sit in some Fedex storage or end up being returned as undeliverable.

Seller is NOT answering email requests to change delivery address to have it held at a local Fedex location, like Walgreens where the wife could collect it from after work.

Oh well my problems but was looking forward to a comparo but not to be for a while... lol.

Have it delivered to me, I'll sign for it in your name :)
