@andrewkelley if you want the very best cleaner for the very best sonics, get an UC (ultrasonic cleaner). Since the automatic UC are $3-4k such as the Audiodesk, you'll have to get a manual one.
I highly recommend a Kirmuss Audio Ultrasonic cleaner which I intend to purchase in a month or so. In July 2019 Stereophile Analog Corner, Michael Fremer begrudgingly (Fremer questioned many of the inventor's scientific claims) endorsed the results as being at least equal and sometimes better than his automatic UC. There are cheaper more homemade type versions of UC out there, but the Kirmuss is a better finished product.
$900 Elusive Disc - package deal
$900 Upscale Audio - 3LPs vs 2 at a time
