Theta Dreadnaught vs. Earthquake Cinenova?


I am getting ready to purpose a new amp to be used strictly in my HT set, no music. I want one which will give me enough current and wattage to get every bit of sound from the movie on every channel without having to blow the roof off with volume. If anyone knows, is the Dreadnaught really worth 2 to 2 1/2 times the money of the Cinenova for HT purposes only (Used 4500 vs. 2000). Will I be able to hear every sound that I am suppose to with the Cinenova as I am sure I will with the Dreadnaught. Also if you have any other recommendations other than Sim Titan which may be less expensive and do the same thing I am looking for please list them. Thank you very much for your input. My system components listed below.

All Vandy Speakers
HT Pro 9+ Cable
Stealth CWS Interconnects
Lex. DC 1 Pre/pro

Thanks so much to everyone for your response. Do you think the Meridian 565 would be good with the Theta and a big improvement over the DC 1 for both movies and music? Everything else from Meridian is just out of my price range at the moment, especially if I buy the Theta. Thanks again for your help.
I think the amp you are looking for is the CINEPRO 3K6SE GOLD. Your application is the exact niche it was designed for. It has incredible power and dynamics, but also is incredibly quiet, and detailed. They are $8,000 amps , and are selling for about $4K right now. Ask anyone who has one. They usually never buy another amp.
There's one selling here now for 3400.00. They sold new for 7500. Extremely quiet and powerful. 500 watts time 5. The best part is that the amp does not run nearly as hot as conventional amps. It has s digital switching power supply. Extremely detailed and great bass control. The Dreadnaught can not match it for bass control by a long shot though it is a fine amplifier. I auditioned both but strongly prefered the Cal audio MCA.
