My tuppence-worth...
When my 'Linn-chip' was still firmly embedded where the sun don't shine and way before the Cirkus kit, I firmly preferred the Ekos II, the ARO with same cartridge sounding a bit messy and 'wayward,' to use hopeless words.. Some of this I put down to the exit cables Naim used, which I believe were French in origin - our Naimie Sales Director bought a drum or two and made interconnects out of it I remember...
The introduction of the Cirkus, together with other subtle LP12 improvements to plinth and the motor 'corner-bolt,' seemed to change things round a good bit I felt. The Ekos 2 sounding rather dark and more than a bit 'mechanical' to me and the ARO taking on a whole new and very positive life, very much suiting the revamped and far less fruity LP12 sonics. Despite the lack of overhang adjustment, we tried many different cartridges in the late-issue LP12 and ARO and most found great favour, although I personally don't rate the DV20 low or high output versions myself.
So, it's up to you! The ARO DEMANDS a current and full-spec LP12 to really shine, cartridges are easily changed by the user and I do feel that this combination is nearer to fit-and-forget for the end user. The Ekos ought to have its cartridges changed by a Linn dealer, who'll then tinker with the LP12 (at a price nowadays
) and charge you for the privilege.
Like I said, up to you
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
