Let me preface this by stating I have not used a Kirmuss RCM myself. I did attend his presentation at PAF in August where he made a good case concerning his credentials and his philosophy on recovering LPs. And considering the deal he was making on his machines, I almost pulled the trigger.
However before I committed I went online and read reviews both pro and con. I’m going to say that I was dissuaded by the reports of cartridges being fouled by some residues left on LPs. Now was it due to poor usage or something caused by the process? I don’t know and want to learn more before I made a decision.
Happy listening.
