@abnerjack , I have a Sota Cosmos Vacuum and I use a Schroder CB tonearm which fits and works perfectly. I am extremely happy with the combination. With the right program source (LP), the turntable, with an MSL Platinum Signature installed, will outperform any digital source I have used in the system. This is extremely impressive. The issue with LPs is that they are extremely variable, performance ranging from insanely good to awful. Digital sources are more consistent. Digital also costs much less. Analog is much more fun.
