Are you looking for an integrated amp or do you already have a preamp?
I noticed that the LM1 is rated at 8 ohms but I'm puzzled by the "(minimum 3 ohms)" phrase in the spec sheet. If these speakers occasionally dip down to 3 ohms, that will be a problem for most integrated amps when both sets of speakers are playing.
If you already have a preamp, then perhaps something like a NAD CI 9060 or Rotel RMB-1506 should work fine. I don't know what the used prices are, but perhaps you could find them in your budget.
