The New Kirmuss Audio Ultrasonic RCM!

Finally an ultrasonic record cleaning machine done right!

I was watching a video from Axpona 2018 by Michael Fremer (always enjoy his videos). At one point he was showing some ultrasonic record cleaning machines that were there. It was the usual crowd from the ill-conceived to the “close but no cigar”. Then the last one he showed just stood out from the pack to me. As I watched and listened to the company owner demo and explain I thought, “Hey, I think I’ve just seen the first ultrasonic record cleaning machine done right”! The second I saw the implementation of the record handling, it hit me. I never thought I would see the day that someone not only made an ultrasonic record cleaning machine done right, but also not priced up in the stratosphere someplace! Well, that day has arrived!

Zu Audio DL-103 phono cartridges

Zu Audio has two versions of the famous Denon DL-103 phono cartridge. The top one is the “Zu Audio DL-103” and the bottom one is the regular “Denon DL-103”

Zu Denon DL-103:

We have kept the great tone of the original Zu/DL-103 and have significantly improved transparency and resolution. Handling has also been considered and improved, with design elements to help safeguard the pickup from accidental damage—stylus guard being the most obvious feature.

The Mk.II update is significant, both in performance and handling. The body is machined from 6061-T6 and hard anodized to aid in the matching of tonearm-mount properties and further reduce pickup stored/reflected energy. The shape of the housing has also been refined to reduce resonance and stress risers resulting in a much stronger design that better supports the motor assembly. We have also changed the epoxy matrix formulation that binds the assembly further reducing noise and increasing stability to the pickup system.

If your system needs a bit more treble energy consider the “R” version. If you are not looking to change the tonality of your system stick with the regular non-R version.
