Theta 1 or EAD Powermaster 2000

I recently purchased a Theta 1 and considering trying an EAD Powermaster 2000. My listening preference is 60% movies 40% music. Can anyone help in this decision as to the better choice in reference to experience with both. I have very efficient speakers from Casta Acoustics(model A) and a great pre-amp. I also run a SVS PB13 Ultra for bass duties. This amp of choice will be my main amp for home theater and 2 channel.. THX in advance...
