Based on the fact that you have an all-Vandersteen speaker setup, one would assume that you are trying to build a high-resolution HT system. HT enthusiasts sometimes ignore the fact that much of the movie soundtrack consists of music and subtle spatial clues, so the better the amplifier handles these aspects of sound reproduction, the better.
The Theta Dreadnaught is a superb amplifier that does a fine job with both music and HT sound, but only you can decide if the extra cost (vs. the Cinenova) is justifiable. FWIW, Shane Buettner, a reviewer for TAS and TPV, uses a Dreadnaught as his reference power amp, and has written about it in glowing terms.
Given the rest of your equipment, I personally think that you will be best served -- in the long run -- by getting the Dreadnaught rather than the Cinenova. I must state honestly, however, that I have not listened to the Cinenova. I have, however, listened to a friend's system which uses the Dreadnaught, and if I were in the market to buy a top-notch multi-channel amp, the Dreadnaught would be at or near the top of my list.
The other multi-channel HT amp which you might want to consider is the Bryston 9B-SST. It has a bit less power per channel than the Dreadnaught, but it's an excellent choice for a high-resolution HT system. I note that you have a Lexicon pre/pro, and Bryston has built the multi-channel power amps sold under the Lexicon brand name.
