I have the same unit and have noticed exactly the same issues with the volume control, not erratic, but very sensitive to small movements and a tad loose mechanically. I suspect that they may have all been this way. One concern I have is that I have tried without success to contact Melos on another issue over the last several weeks without success. Phone and e-mail have failed and their website isn't running. I believe that they may have closed up shop. If you know one way or the other please let me know. Don
Melos Maestro erratic volume control?
I've had my Melos Maestro Pre-amp for a little over a year and it sounds absolutely fantastic! Unfortunately the volume control has always been much too sensitive! The volume is very tricky to adjust to a comfortable listening level: it's either too loud or too soft. There seems to be a lot of "play" or looseness in the linkage from the knob to the mechanism inside. This looseness erratically varies the volume both ways. I have had several people accidentally turn the volume up too loud because it is so touchy. I also believe this problem may have led to a blown tweeter in my right Vanderstein. I can't confirm this but it is feasible. Has anyone else experienced this problem? I believe my Maestro may have been from one of the first production runs. I talked to someone at Melos a day after receiving it and the person acknowledged the problem but didn't seem to have a straight answer for me. Perhaps the problem was too new at the time(?) My unit continues to amaze me with it's incredible clarity, resolution and musicality. I'd just like to get this volume issue resolved. Thanks in advance,
