Michael Fremer's record cleaning process....

Michael

On the KL Audio / Audio Desk - I apologize if that came off as stating you
were bought off by advertising, not my intention. I merely noted that your
site advertizes the AudioDesk ultrsonic machine

Here is your statement on the KL Audio

When I emptied the KLAUDiO’s tank, the pulverized dirt particles removed
from the records were in suspension, which means each record cleaned
after the first few will inevitably be “cleaned” with dirty water. I can imagine
a scenario where the pulverized dirt particles in suspension are within
cavitated bubbles hurled at great force against the vinyl. No doubt that can
happen in the Audio Desk too if you don’t change the water frequently
enough, yet the sonic results with both machines were consistently superior
to vacuum cleaning and often times miraculous as chronically noisy records
were rendered quiet.

The "residue" is soluable - not a hard substance

I don't recall that same cautionary comment being applied in the initial
Audio Desk review

sorry if this came off overtly critical on my end

Thank you for all that you do for keeping the analog flame alive

Fremer has been a good advocate for the analog cause
He is one of us

At one point he was too much a cheerleader for whatever came out on
vinyl. Now with many comments from listeners and the Steve Hoffman
forum, he has become more objective - comparing current "highly
toted" releases with original pressings etc. this has helped me decide
whether to spring for that touted remaster, realize my great sounding
version is ideal, upgrade to a new pressing, or seek out an original.

I also have an Ultrasonic cleaner but went with the KL Audio for many
reasons. Fremer tried to downgrade that machine and scare people into
thinking it could pit their records when it utilizes the same principles but is
better executed. He owns an audiodesk - which was the first US
commercially available and he is supported by their advertising.

I kept a Loricraft for rare heavy duty cleaning. The ultrasonic is such a
revolution in noise floor, lack of pops and static, low level resolution,
imaging, body around the instruments and separation.

Unfortunately it is $4k. I wish more could experience it.
