Did you try different components? I had the same problem with my Thiel 3.6 speakers distorting certain solo piano notes and Thiel said they could rebuild the driver if I remove it and send it to them. However, I picked up an SACD player and the distortion did not appear when playing the same disc. Turns out it was a bad polypropylene cap in the analog board of my Theta Gen Va.
Refurbishing Avalon Ascent Mk 2
After 25 years of service my Avalon Ascent Mk 2 have started to distort especially with classical piano. I have isolated the problem to both 2" aluminium-manganese mid drivers. These, I believe, were built by MB Quart of Germany, now out of business and the part seems unavailable.
I would greatly appreciate any suggestions on how I could bring back these speakers to their former glory. Thanks.
