Preamp for Bryston 4bst

The Audio Research LS-3 and Bryston ST series amps have excellent synergy. This I know after running an LS-3 and 4B-ST together for several years, and then moving on to a series of much more expensive components thereafter. In fact, the dealer I bought this combo from spoke at length about their synergy, saying the LS-3 bested Bryston's own preamps with the 4B-ST and the more expensive ARC LS-2.

Provided they are left on 24/7 and used with really good cabling, the LS-3 / 4B-ST can sound incredibly good for the money.

I think that an ARC pre is the way to go.

Can't comment on the realm of options, but I fed my 4bst with a VTL TL 2.5, then a Rogue 99 Magnum, and am now using a Plinius CD LAD (Mk. II). Works for me.
