I own the Dreadnaught (5 channel model)- fantastic SS amp (check Theta's website for re-printed reviews). The Dread does 2-channel with a finesse that I don't believe you will find in the Powermaster.
However, if needs are HT only, then compare the 2 amps.
Re: HT processor- I use the Sim Attraction. Its basically the EAD signature top-of-line with better power supply and analog section. I A/B's it with the Meridian 561- Meridian has the edge on steering logic (they are the kings of digital-based surround), however, the Sim is a smoother, more rich sound, and less fatiguing to my ears. I believe the Attraction (~$5k) is priced above Meridian 561 ($??), but below 568 (~$7k).
Sim Attraction sounds better than Theta Casonova AND Casablanca. Believe me, I would have bought Casablanca, as the 'look' would have matched the Dreadnaught perfectly, however, the Attraction just sounded better- balanced outs on all 6 channels (5 and sub) OUT OF THE BOX (i.e. no $$ 'add-on options like Theta Casanova/Casablance).
E-mail me with any further questions, and good luck! (All I know is, you will NOT regret purchase of Dreadnaught- I sure don't. Makr sure and get the optional silver-titanium finish/ top cover combo though- very cool...)
