What makes tape sound better than vinyl ?

Some information is correct while some is misleading or plain wrong.
The very best Nakamichi deck is 1000ZXL, Limited and regular. The very best Tandberg, aside from pro models, is 3014A and 3014 is close. Revox cannot compete at this level. Studer is better, uses top Sony heads, but cassette Studer is not reel Studer.

Revox B710 and B215 should be good for your purpose, but they are expensive as well.

I have no idea why I'm wasting my time trying to help somebody find a cassette deck when it makes absolutely no sense; right now I'm listening to the 2 track, and no cassette deck I've ever heard is even in the same ball park.

I "gave" my ton of cassette tapes away, and never looked back. A good cassette deck is not cheap, and with a few more hundred, you could have a good reel to reel. Plus I've seen reels that cost no more than expensive cassette decks, but audiophiles can rationalize the irrational.

I certainly appreciate the help and advice and seriously hope you do not think you are wasting your time!
Since when has any audiophile been accused of being rational.....lol.
It may be a passing phase but its one I am interested in right now.
R2r may follow who knows?
From what I see of the successful sales of cassette decks on eBay I would have little problem moving a deck on again at a later date.

The main problem with ever increasing budget is that pretty soon I will be approaching r2r prices and then its well just a bit more will get an even better model , repeat ad infinitum!
I am in no rush, tapes have sat in boxes for 6 or 7 years now so a while longer will not hurt.
Lets see if I can find any Xmas bargains!
