Is it worth purchasing the VPI 16.5?

A record cleaning machine is definitely a worthwhile purchase.

However, I find it hard to recommend the VPI 16.5. I recently purchased one new and it arrived with internal wires disconnected, and then the vacuum motor failed after cleaning a few records. Still trying to get it fixed. Customer service and QC does not seem to be a high priority for VPI these days.

On the other hand, I have had a manual Nitty Gritty vacuum record that has worked flawlessly for 2 years (but manual is a pain).

Have to look into the SOTA...

The Sota looks good, but I have a 16.5. Galen Carol has the best price I've found by far, and he is great to deal with. Whatever way you go, a good RCM is a must. Without opening the cleaning fluids debate again, I only use Audio Intelligent Vinyl Solutions. DD brushes are good too, as are the Last brushes. Don't forget a good carbon fiber brush to dust before you play. The VPI brush works great for the first cleaning cycle.

Because the string is replaced each time you use it and because the arm tracks the gooves, I would strongly recommend the LoriCraft record cleaner imported by Smart.

I have owned several VPI and NG cleaners. In each instance where I further clean a record previously cleaned on the VPI, I hear a substantially quieter and more transparent sound after cleaning with the LoriCraft.

Just want to second Jphii's recommendation of the Audio Intelligent products. They do a fantastic job. As to record cleaners, I still prefer the simple Nitty Gritty (or Record Doctor) manual machines after some 22 years of using them.

FWIW I have the SOTA cleaner. Love it.

Have Fun.
