Best sounding,reliable, tube amp below $700 used


Hi, I thought I'd throw out this question to everyone, and see what their opinions are. I'm sure there is a wide range of opinions on it, so the full question is: What is the best tube amp under $700, on the used market, in terms of both sound quality, and reliability?
Thanks

Someone just listed an Aes/Cary Ae-25 Superamp that would be very hard to go wrong with. Apart from that, Quicksilver Mini Mites (monoblocks) also come to mind. Good luck!
Cayin TA-30 integrated. Essentially the same as the Primaluna Prologue 2, but goes for $600 to $700 used on Agon. They sell really fast though.
Extremely well built, hand wired, can run in SET mode or 35wpc with EL-34 OR KT-88's. Very quiet and holographic.
Agree with Mwilson--QS Mini-Mite Monos are excellent for the price ($998 new, ~$650-700 used).
Thanks for the replies, I've read about the mini mites on an old post here, and also the Conrad-Johnson mv-55 seems to also have a lot of backers. Please keep the opinions going.
What type of speakers will the amp(s) be driving and what are their specs?

And what some tube amps that you've heard and liked along with others that you didn't?
