From what I know AN we're rewiring and hot rodding Rega arms before they started making their own.
Yes - 20 - 30 years ago.
Are you going to buy a 20 - 30 year old tonearm ?
They also worked with Helius 20 odd years ago for a brief period too., and Systemdek, and Voyd and .....
And then of course whilst acting as agents for Audio Note Japan/Kondo they registered the Audio Note name in the UK & Europe, and then dumped Kondo and launched their own "Audio Note " products.
Not a very ethical company in my view and personally I would never buy any of their products for that reason.
