John, I'm driving my dips down to 3.6 ohm Avalon Acoustic Eidolons with a pair of MFA M200s on loan. Their presentation is only slightly different than the Carver VTA 180s (2, 4, 8 ohm taps) that I have settled on.
Other amplifiers I've used with these speakers are the Ayre V1-xe, NuForce 9SE v3s, and the Hypex nCore 400s. Three very different presentations.
With the exception of CJ your short list is interesting. The CJ Premier 350 may be very underrated and well worth a listen.
