Proceed AVP vs. Sim Attraction vs. Theta Casa Nova


I am replacing my Sunfire TG II and would like your thoughts on the following processors:

Proceed AVP;
Sim Attraction; or
Theta Casa Nova II.

While I will use the preamp/processor primarily for HT, I also would like one that does a good job with two channel. The principal reason I am selling the Sunfire is my dissatisfaction with the quality of the two channel audio in my set up.

The rest of my system is as follows:

Nautilus 805s and the matching center;
REL Storm III sub;
Bryston 9B THX amp; and
Sony DVP-S9000ES DVD player.

I am trying to make a decision as soon as possible, so any thoughts would be greatly appreciated.

Thanks in advance.

I sold a proceed to buy the sunfire series 2, imo the sunfire works well with 2 channel, I am using a krell kav 1500 with aerial 8b speakers, the prepro's you mention will not give you much improvement in 2 channel, to do so , you would have to step up to the krell hts or possibly the classe ssp 75, I tried variuos prepro's in a attempt to improve 2 channel, but I found going to a higher quality amp helped more then changing prepro's, good luck in your quest.
If you want excellent 2 channel without spending the money for a Classe 75 or Lexocin MC12, find a used high end 2 channel with a SSP bypass such as the Levinson 380 or 380s and keep your current setup for HT.
I have the Attraction- it has by far the best analog/preamp section of the ones you mention.
