Usher BE-10/20, what do you use to drive them?

So I gathered some muscles are needed to move those big Eton woofers, not a surprise. My little BE-718 is very power hungry too, but they do so wonderful with Plinius 9200.

Reason I am seeking for amp advice, Usher BE-10/20 are more analytical than 8571/8871 and many other speakers due in part to the BE midrange which is super sharp and detail. Almost like a Leica lens if you will. So getting a super detail amp like Halcro or Spectral might not be ideal given the nature of the speaker. McIntosh sounds like a good idea, but will it mask out too much of BE's strength? Plinius is usually associated warmth, I think that also explains why Jeff likes it with the big Usher.

Without spending a fortune, say in the $5k range for used amp, what else is capable of getting the most out of the big Usher?

Has anyone heard them with OTL amps, such as the Atma-Spheres or Joule Electras? Cheers,

Spencer

Semi, for $5k, look at Parasound Halo JC1. I almost got these instead of my Ayre MXR. For the price, I dont think you will find many better amps.

BTW, I agree that the Ushers need a decent amount of power. I believe the impedance drops to 3ohms in the lower freqs.

The 100W/ch Jadis might be a good combo (Defy 7?).
