I assure anyone who cares that the Cornwall IV can achieve extremely loud levels with only 20 watts of tube power in a relatively large room. I do it all the time.
Better Amp for Cornwall IV's...
...Parasound 2250 v.2 / 200 Pre combo, which I own, or Denon PMA-1600NE integrated, which I don't, but I admire the build quality and appearance of? My Parasound is rated 275W into 8 Ohms / 400W into 4, while the Denon is 70W into 8 and 140 into 4. Of course, the Klipsch Cornwall IV's are quite sensitive and are rated 8 Ohms. Maybe more than which is better, which would you all prefer?
