Best Multichannel Amp - ???

The Theta Dreadnaught should be on your very short list. It has gotten excellent reviews by many people, including Richard Hardesty who selected it as the best multichannel amp from a group that he tested about a year ago.

I'll second the Theta Dreadnaught as I considered it before I bought my Theta Citadel monoblocks for my 2 channel. It is a very involving amplifier (not as dark as the BAT on the top). If you can find one used an EAD Powermaster 2000 with 400watts by 5 channel is an amazing multichannel amp, but the Theta has lowest bass octave covered while the EAD is warmer.

While I have not heard the Odeon, I have experience with the BAT you list as well as another highly reviewed unit, the Ayre V6x. I bought the Ayre and do not plan on upgrading my HT power anytime in the near future!

I give a STRONG second to the Ayre V-6X. I have had it as well as the Theta Dreadnaught 1, and while both were truly outstanding amplifiers I opted to keep the Ayre unit over the Dreadnaught. Teamed up with a pre-amp that offers HT pass through and you truly can get the best of both worlds with either the Theta or Ayre unit. The V-6X gives you everything the renowned V-5X does and has a pass through format between its channels that make bi-amping a snap. The Ayre's don't show up used often, and after having one in my setup for over a year I can certainly understand why! I did recently sell mine, but only afer I had auditioned the Ayre V-1Xe which took the two channel listening to yet another level. I'll need to find a decent amplifer to drive the rears now, but its a trade off I'm willing to take!
