Thanks guys for the suggestions. I've evaluated everything that has been suggested here. Rhljazz has hit it on the head. Maybe other appliances generate more heat but I doubt it. When you have small room with a 14 tube amp it's like putting a heater in the room. The past few days I've been using the BelCanto's and just maybe I've been concerned for no reason. The Bel Mono's are really close to the Prima Luna. Not quite there but close. In fact with a few tracks on my play list I thought they might be better. For me personally it seems easy to sway my impression of what I'm hearing. I can tell it's, different but sometimes different can be a nice change. Don't get me wrong I can tell if something is crap (for me) but in this case both systems are very nice. I guess I just got used to the Tube sound over the winter. I might still look for a fix, but a air conditioner in the window isn't one of them. As for fans and vents to take the heat away I've looked at that and for my room; not gonna work. Thanks again.
