Your sda's will love that carver. The 45 is one of my favorite amps to power mine with as it has such a deep soundstage.
You guys realize this thread is over 5 years old, right? It was resurrected by In Tune to ask about powering his Polks. I would imagine the question about whether to go with the Carver or Parasound was answered a long time ago.

UPDATE! I have had this Carver going on 3 yrs now, It's been nothing but a pleasure to own and hear with my SDAs,(upgaded to the new tweeters). I wish I had a better preamp/receiver though.. The Harmon354 is still in use with this system. Someday something better when cash permits.
Recommendations welcomed now though for that day. Would still have to be Budget minded...
The thread that wouldn't die!
Glad the TFM is working out for you, In Tune. Are you looking for a straight 2 channel preamp or something to run the Polks as fronts in a HT setup?
