Kuzma Stogi S univpivot tonearm

I bought the excellent tonearm from a friend in Penang and it comes complete with box, manuals and setting up tools. I never used a unipivot before so I thought I give it a try on my new Acoustic Signature Challenger turntable. This tonearm is quite highly rated by The Abosulte Sound magazine and is solidly built. Other famous current unipivots that comes across my mind : Graham Phantom, Naim Aro and JMW 9.


I need to machine the arm base hole on the Acoustic Signature from 28mm to 30mm and add 3 fixing holes of 6mm in order to securely mount the Stogi S.

Acoustic Signature Challenger turntable

Now, the main source is from this turntable which was bought used from a Singaporean. The TT is equipped with its own outboard power supply unit which outputs 12VAC (frequency adjustable) and preset at 2 speeds 45 & 33.3 rpm. It replaces the Linn LP12/Ittok LVII that has been around since 1980 and still performing well.

A Boston Audio Mat-1 solid graphite platter mat replaces the stock felt mat.

The tonearm is a unipivot Kuzma Stogi S bought from a friend in Penang. Cartridge options : Denon DL103R and Benz Micro 20E2L both moving coils. Phonostage is Japanese made Softone Model 4 which uses built-in step up transformers for MC inputs and 2 Sovtek 12AX7LPS tubes for amplification. The stock tubes have been replaced with NOS Mullard M8137s (CV4004). More on these later ....
