Vandersteen 1c, and an integrated

as a ex owner of the 1c ...i would easily recommend blue cirlce , naim nait 5, i also used s.e.t amps with the speaker from 2 - 20 watts with nice results in the bedroom...smaller room and also any of the rega amps sound great as well ...these are 90 db effecient..so even low power tube amps work nicely...hope i helped !!

Your list looks great. I would second the addition of PrimaLuna ProLogue I or II integrated tube amps. NAD 372 might be fun with all that juice.

As a current owner of 1B's I can tell you they sound fantastic with a Music Reference RM-10 which could probably be found used and paired with Roger's pot in a box for right around your budget.

Music Reference RM10 is a great little amp (I have owned the RM 10, RM 9 and now the RM 9 Special Edition). If the RM 10 can drive the VS it would indeed be a great, affordable set up, and I can vouch for the Pot-in-a-Box which I interchanged with my Joule 150 MK II which I preferred to Lamm, CAT, and Placette Active - in other words a $150 pre that competes with some heavy hitters. I'm still suprised that that a low power tube amp can make the best of the bass potential of the VS1s, but theory and listening are two different things. Hard to find the RM10 used though ($800-$1200 -MKI,MKII- when they do show up).
