Hi,
I just bought a pair of 802D powered by a Classé CA-2300 and Classé CP-700 preamplifier. I notice a hissing (not a noise but a subtle constant blowing hissing) in the diamond tweeters. When only the power is turned on the hissing is almost unheard but when the preamplifier enters the hissing becomes more noticeable. Is that normal?
Regards
