Tube Pre-Amp for Class D amps


All,
I have a old AR LS-8 that i pair with channel island d-200's I like the sound but want to upgrade pre-amp with newer and one that has remote volume.

Would like to stay under 4500. (new or used) and still want tubes.

Thoughts? thx much in advance

I am using a Modwright tubed pre-amp with Wyred4sound class D amps (and before that Bel Canto class D amps) and think they complement each other very well.
I have a Cary SLP03 paired with my Spectron amp. Very enjoyable and lots of flexibility.
