I used to have an older Rowland Concentra that did run very hot (say about 50 degrees Centigrade on the outside). I would think that the interior temperatures are quite a bit higher. I liked the sound and the convenience, but sold it to go to an all vacuum tube amp-preamp system (because of the sound). It is true that tubes run hotter, but they are meant to. Solid state devices tend to degrade when subjected to high temperatures for prolonged times.
Krell knocked off Jeff Rowland
I had an opportunity to see the new Krell productlines. Am I seeing things or Krell designers are having designer block and they're trying knock off Jeff Rowland's design? On to bigger and better things. I also had chance to listen the Jeff Rowland's new integrated amp. The units seems to run very hot. Is it because of the new cleaner designs which has no heat sink fins? What do you felow audiogoners know about this heatsinkless design?
