If he is not responding, it is most likely that he's out of town. I once sent him an email while he was out of Germany and he replied to it once he got back to Acoustic Signature.
Just be patient.
Just got a platter upgrade
For my Acoustic Signiture Final tool I upgraded to the new platter with 24 brass silencers. I noticed the difference right away. Images where sharper and more details came out. Gunther sent me test results showing vibrations diminished with the new platter. Anyone else had this upgrade? I want to get my motor upgraded but having difficulty reaching them. Mike
