Dante,
Dante, For the smaller OHM 1000s, I think you have many very good options that would appear to match well to your pre-amp and outperform the Arcams:
Musical Fidelity A3CR $600-$700 used this is what I am using and can voutch it sounds great with the OHMs and it provides plenty of power and current for my OHM 100.3s in my 12X12 room and does a hard to fault job even with OHM 5s in a much larger 20X30 L shaped room (my largest).
Other larger amps I have seriously considered (more for the 5s in the larger room than the 100s):
Wyred 4 sound st/sx/250 - should be within your $2000 price range
Audio Research D400 mkii - one up for sale here currently that has caught my eye
Musical Fidelity A308CR (one up here currently by a local to me seller that I have considered)
Musical Fidelity A5CR - step up from my current A3CR
I also like Classe amps for use with SS pre-amps in particular though I cannot suggest the Classe models to consider in your range without further research.
