I have the vzn 100's and have had zero quality issues in two years' use - not one issue. The musicwood is quite nice so I have no complaints about build quality. I also have the joule LAP 150 MkII preamp and have had no quality or performance issues whatsoever. The sound is wonderful. The amps do put out some heat but it looks like you have nice high ceilings in a good sized room so it should not be anything the ac cannot handle. I switch over to a Berning amp for July and August in my room (smaller than yours especially the ceiling) - as much for the change of pace as the heat.
Joule - Electra: Just How Hot??
I'm considering Joule Electra mono blocs as a source of amplification. My fundamental question is not about the sonics rather this is a question for those that actually have J-E in their system: How much heat do they throw off and how do you manage--especially in the warm months of the year? Or is the heat issue not really a major problem? My room is 25 X 17 X 13 (LxW xH)with 4 air conditioning vents and 2 heat extraction ducts.
