Anyone here using this amp? Thoughts? How does it compare to the Parasound or Sherbourn 5/1500? I'm using one now but have not been able to hear one of the others. My dealer wants $1499 + tax with no discount for the Anthem. Unfortunately I have to go all the way to Houston to listen to one of the others. Any comments would be appreciated. Right now I am using this amp with Polk speakers but in the future would like to upgrade to Paradigm Studio 40's,Studio Center and Studio 20's for the rear.Thanks.
