is there a great used tube for 1000??

there's a Music Reference Rm-10 and an RM-9 avaialable on this site for $650 and $900, respectively. The RM-9 is a former stereophile class b and the little RM-10, which I have is outrageous with 89db or higher speakers.

A used Quicksilver or Rogue would be really hard to top at this price point. The Rogue is more neutral sounding, the Quicksilver more "classic tube". If you prefer an even more "classic tube", rich, warm(some would argue overly so) sound, the CJ MV-55 is also something to think about. Be sure that the EL34 powered CJ will be able to drive your speakers to your satisfaction, however. It is not a very powerful amplifier.

Which quicksilver model?

Kitch is right. The Music Reference is a classic tube amp. The RM-9 replaced a pair of Quicksilver monos about 6 years ago and I forgot which models.

I was referring to a used pair of Quicksilver mono amps. Either the 60 watt version with KT88's or even the 90 watt version, although the 90 watt (Silver Edition) usually sells for a little more for than $1000. You should be able to get a used pair of the 60 watters for around $1000. Quicksilver also made a 40 watt stereo amp which should probably sell used for around $1000 or less, however this may not be enough power for you.
