Just made my first serious separates purchase. I bought a used Parasound HCA-2003. It’s running my mains (L&R) and center. I want to thank the Parasound HTF owners for the tip. Now I understand what all the separates buzz is about. The sound is dynamic and forceful without being harsh! It gives a low end to my JBL S-310II’s that wasn’t there before. It makes listening to my reference SACD/DVD-A’s a religious experience! I also have some concert DVD’s that sound equally as good. Question! I don’t have the unit racked or in a cabinet. I have six inches above and to the sides as recommended in the manual. But, is it normal for it to run very warm to the touch even at moderate levels (75-85db)?
