The temperature on the surface of my DS junior is unusually hot. It measures 125F (52C) on the top, 115F (46C) on the front panel and 130F (55C) on the back panel. In comparison, BHK 250 after 2 hours playing at about 30% gets to about 125-130F (52-55C) on the side heat sinks and much less on the top and the front panels. The BHK preamp is not hot at all - approx. 97F (36C). All measurements are taken with a reasonably accurate infrared thermometer.
My setup is Lenovo notebook running JRiver22 playing thru the bridge of DS Junior -> BHK preamp -> BHK250 -> Magneplaners. All interconnects are balanced (wireworld equinox7 and Nordost red dawn), except for the speakers. The volume on DS Junior is 100; BHK preamp’s volume is 30.
I am not sure whether this a problem at all, but nevertheless, I am a bit nervous. I would appreciate it, if someone confirm if this is normal or not. And if not, what can be done about it.
