I would suggest an Audio Research LS-15 last year they were going for $1500 this year there down to about $1100. Search the discussion forums and you'll find many positive posts about this tube pre. added bonus' are that it has a remote, it is fully factory supported and is a well known reliable piece. I am running one with the same VDH interconnects as you. This pre has matched nicely with my Classe and Rowland amps. My source is a Denon dvd-5000 as a CD player.
