3 head cassette decks

I still have a Yamaha K1000, but don't use it very much. It has 3 heads, 2 motor direct drives and was one of the few decks that has DBX. It still sounds great.

The NAD 6300 should be in the mix, an excellent machine.

Believe it or not Sanyo made a serious deck back in the day, the 5370. You can buy them dirt cheap, IF you can find one. I still use it to make tapes for my car, it's a great sounding machine.

I second the NAD 6300. I have 2, both broken.
