Turntable upgrade recommendations: SME vs AMG vs Technics vs other

I use a lab grade US tank, made by Elmasonic. Runs at 80KHz or 37KHz - I use 80, and a rotating spindle to run one revolution per 9 minutes. Usually once through is enough, but some garage sale specimens have required 3.

Two threads might interest you: one here on Audiogon by antinn, a high class expert in cleaning technology. The other is a long thread on DIYaudio. Turns out that 80KHz is a really good frequency for records.

The reasons you might want a lab machine are: 80 KHz, internal heater, enough consistent power, and generally meets spec. As you know, lab equipment has to meet spec or there is Hell to pay. Consumer audio, not so much.

Bit of a DIY approach, but that's my style ...

Plenty to learn from in the link about Methods to clean Vinyl LP's

I am using the Manual Method and on a Batch of Six Plus LP's can clean in approx' 10 Minutes per LP.

I did intend on using the owned US Tank for the final rinse cycle, but the impressions made has created the condition of a LP where it is felt and additional steps are not needed.

The Manual Method is not as convenient, but is very affordable and the 'Job Well Done' aspect is quite satisfying.   

Precision Aqueous Cleaning of Vinyl Records - The Vinyl Press

You might want to ad SOTA to your list. I have a Star Sapphire table with vacuum hold down and a SME 309 arm on it, a very nice combo IMHO. The SOTA tables being produced now have been seriously reworked for the better, magnetic levitation bearing, new motor and motor control units and are reliable to a fault once setup. Music flows out from the table and expands to fill my room with a wall of sound and I couldn’t be happier. And also, they don’t cost a fortune and if you need help, just call them and you more than likely will get one of the owners to answer the phone. Great customer service which is invaluable when purchasing and setting up a top tier turntable.

Thanks @pindac  . Could not remember the exact reference. VERY useful.

Vinyl has a few ritualistic disciplines, that are a Joy to behold when all are synched.

Developing the want for participating in the disciplines and acquiring the required lessons and equipment necessary to develop the skills and additional practices can be as much fun as the listening experience, even though a little more mentally challenging and less restful when taking part.
