Hi guys,
Maybe someone can drop me a hint to a solution on the following issue. Sound level from my Denon PMA QS10 mk 2 is not stable. Volume drops and rises again but it is hard to put a finger on when this occurs exactly. Quite anoying it is. Most of the time sound quality remains good but sometimes serious distortion can be heard when such a drop occurs, especially when it comes down from a higher soundlevel. It looks it is more sensative for this behavior at low volumes. Then also, more drops follow one after another. The amp has all new and original UHC-MOS components done by a professional technician. Have tried several loudspeaker arrangements, currently B&W 801-S3 (with refurbished tweeters, aka new ferro fluid added) in series with OLS (Kharma nowadays) with Van Den Hull cables. Tried all possible settings too, amp warm or cold, sound direct on/off etc. Amp too good to put on a shelf and make it a museum piece. Anyone idea's? Much appreciated, thanks for your time anyway. Best regards, Jan (Belgium)
