Thanks for that explanation, Jonathan.
I have been into hifi (for want of a better word) for 50-odd years, but have never had an SME tonearm.
I have only ever had three tonearms during that period.
The first was an Infinity Black Widow, with a graphite armwand, on a Thorens TD160S deck (with Ortofon MC20 moving coil cartridge), which I sold to a friend when I got my Linn. The Black Widow was very stylish, in a skeletal sort of way, but was not sufficiently rigid to avoid colouration.
When I bought my LP12 in 1990, I went with the obvious choice: an Ittok, although I opted to pay the 10% extra to get a black-finished one, as they were reputed to ‘sound better’ (which may or may not have been true, as I never heard a back to back comparison).
In due course, I opted to have an ARO installed on the LP12. I suppose that I must have traded in the Ittok, as I have no recollection of selling it.
Ray Horn at Grahams HiFi persuaded me to try a Dynavector XX2 Mk II, and I had two or three of them for them for the next 30-odd years.
Then last year, as the XX2 Mk II needed to be replaced, and just before a bout of ill-health struck me, I had a Dynavector Te Kaitora Rua fitted to the ARO. And what a stonker that is - beautifully clear and precise, with a great bass response. I think that I have found my ideal cartridge, and its open, skeletal form suits the ARO’s own minimalistic design. A wonderful match!
