REVIEWS & TECHNOLOGY
The Sonic Art structural mod kit is back! The
rear of a Rega arm is extremely important as the
counterweight represents the highest mass of the arm which affects the arms
performance significantly. As your cartridge tracks its way through the grooves
of your record it sends micro resonances up the tonearm tube, some of this
vibration sinks into the base of the arm but much of it travels into the end
stub/counterweight assembly where it is reflected back down the arm tube, not
the most ideal situation for extracting fine detail.
So the first task is to remove the plastic
end stub and add an end stub to the arm that is like an extension of the arm
tube itself, incredibly rigid yet at the same time semi decoupled. We have done
this using high grade non ferrous metals. Our end stub is not
screwed onto the arm tube like the factory & most aftermarket stubs, our
end stub butts up against the back of the arm tube much like the old OL stubs
did, with minimal surface area interaction (decoupling it) and is torqued into place with a thin stainless bolt that screws
into a brass insert in the back of the arm tube.
We end up with an essentially rigid arm
tube, yet decoupled where the counterweight mounts. We then add a solid machined
brass counterweight, close tolerances and rigidly clamped to the stub via a set
screw, the sonic characteristics of the brass sink the unwanted resonance waves
from the arm tube. We use premium materials for all components, Australian
brass and alloys.
The modified RB series of arms have been
spoken of as giant killers by many reviewers over the years, focus, detail,
dynamics and bass weight, the consensus is a significant improvement in all
areas. Add to this internal and external rewiring for a truly unique high
performance arm. Our end stub kit will fit any Rega /
OEM arm, RB250/300, RB202/302, RB220/330, and any of the higher spec Rega & OEM arms.
NOTE:
