IsoKinetik ISOweight

  (3 Reviews)

A surprising improvement” Neville Roberts Hi Fi World

£41.66 Exc. VAT |  



IsoKinetik ISOweight

Available in 3 different weights to suit the weight of your cartridge 103g, 130g and 144g

Please Note: Customers like to use this weight with many Manufacturers Arms and due to the many permutations of tonearms and tonearm length, weight etc, and cartridge weight combinations it is not possible to specify which weight would be suitable for any individual customers set up and tonearm length, weight etc,

We recommend use of a newton meter, strain gauge or other method to ascertain the weight required to balance the tonearm,  note this weight and then order the appropriate Model 1, 2 or 3

Rega tonearm counter weight- incredible audiophile value for money

Asymmetrical design lowering centre of gravity exerting less pressure on the bearing

Exceptional sonic improvement due to improved tracking, placement of stylus in the groove


Fits Rega RB300 RB301 RB600 RB700 RB900 RB1000 also Moth and other Rega derivative arms



The stock Weight on the Rega tonearm Gyrates as the Stylus slaps around in the grooves causing tracking errors that muddy up the sound.The ISOweight does NOT GYRATE in this manner.

As a result of its unique asymmetrical design (works like a balancing beam for Superior Tracking, roll both weights on a flat level surface and you'll see for yourself) and precision machining, 





“Best bang for buck? The ISOweight at under £50 is the first thing to have on your shopping list- its great value and a surprising improvement” Neville Roberts Hi Fi World

I got this to enable for use when I raise the tonearm on my Rega RP8 to use with Sumiko Blackbird Cartridge. The dustcover no longer touches the contuterweight. Also, the sound quality stayed as good as it was with the Rega weight.

Great bargain

I am using this counterweight with a Dynavector Karat 17 d2 cartridge: There is a great improvement in the tracking ability:
I am using it on a Jelco 750 tonearm : I have made some cd with and without this counterweight: comparing with the original counterweight the improvement is huge.
Thank You.
Best regards.
