I have used all sorts of clamps including SOTA's own excellent mechanical clamp, but after getting my SOTA Star vacuum some years ago, I have retired all the mechanical clamps in favor of the vacuum system. Just today I played a set of records which were "dished" . The vacuum was able to flatten them, whereas a clamp would be useless unless it used a rim ring.
SOTA vacuum or no?
I am considering a new SOTA Sapphire or Nova as a replacement for my VPI Scoutmaster. I am aware of the differences in features between the Sapphire and Nova, but the biggest difference is obviously the presence of the vacuum clamping system present on the Nova. Is it worth it? The price difference between these two SOTA's is about $1400, I think. I am curious as to the reliability of the vacuum system, sonic benefit versus using the SOTA I-clamp or Reflex clamp alone. Also, how easy is the vacuum system to live with? I'd prefer minimal tweaking, if possible. Thanks!
