I'm a big fan of the Superphon line.

Here's one:

Superphon Revelation

Stone cold bargain.

If you can find a Revelation II, even better!

Worth a listen.

If you can live with only 2 inputs, this would be a low cost, low risk alternative.

If you can save a little more money and stretch a little bit, say 600 or so, you can find an older Audio Research LS-3 or CJ PV10A with a little patience. You'll never have a problem selling them for around what you paid if you get more ambitious.
