The design of XTC puts its lowered Centre of Gravity closer to the plane of the stylus than other "dropped" counterweights can manage.
The rotational forces have less vector variation which improves tracking.
XTC is available for a number of arms, and has consistently had positive effects.

Remember where you saw this counterweight first. I endeavour to produce innovative products, not me-too ones.
This design is protected by Design Registration and made right here in Kent, England.

The counterweight itself is lacquered brass, with an aluminium collar and stainless steel set screw. 
See my other listing for a heavier version for cartridges weighing more than 8gm.

Good product, great seller. Couldn't be more helpful. 10/10 (Light for F.XR)
Message: I've left feedback. I'm really pleased with the weight by the way. I've been getting a tiny bit of distortion
towards the middle of discs, which, having eliminated everything else, I think can only be down to tracking error.
It seems better now, so I'm very happy. Looks great too!

My brother Tim recently bought your counterweight for his new Funk FXR11 tonearm to which I had the pleasure of an
evening with hooked up to my modified Rega 300 bolted to a hot rodded Audionote TT2. Suffice to say my
tracking (Which was already very good) improved greatly sounding like my tonearm had suddenly grown 3 inches! Wow!
I won't bore you superlatives, suffice to say it is the most cost effective upgrade I've ever heard. Reluctantly I returned
it to my brother and vowed to have one ASAP!

Beautifully made and engineered product from a great E-Bay seller. Recommend. (Hadcock GH220)
Christopher, UK

Tried out the counterweight last night. Amazing improvement over the stock CW in every way. Most noticeably, as they say
so often, a veil is lifted. Everything is less tentative. Bass coming through more solid, percussions  have the final "ring" of
the real things, more depth and soundstage anchored more accurately. These are all preliminary impressions after a few hours
of listening. I have no hesitation recommending your CW to Hadcock owners if these prelim impressions hold up & I think
they will. (Type GHS - GH242)
Message from Isidore, Australia

Very good seller, I highly recommend it. (Type R - fine adjust)
Roman, Czech Rep.
Really cool counter balance! (Type R - fine adjust)
