The ARO was certainly an ergonomic challenge. But my real objection was that it sounded awful - thin, lightweight, no bass.
"Thats not my experience.
I own several arms including Aro/Dynavector/FR64S plus many others.
In a direct comparison using the same cartridge on both the Aro & Dynavector there was no lack of bass from the Aro. Dynavector was tighter in the bass, but the Aro went as low and remained tuneful ( good timing ).
I would be looking elsewhere in your system for the thin sound. What I do know of the Aro ( I've owned it for over 20 years ) is that I beleive it has a narrow operating range with regard to compliance & tracking weight. High compliant cartridges and very low compliant cartridges with long cantilevers tend to be less compatible with the Aro."
I agree 100% with what Dover is saying above. I have compared the Linn Ekos with my original Naim Aro with the same wood bodied Benz on my LP12 and far preferred the Aro. The Aro certainly was not lacking in the bass. The Aro presents music in a very natural, organic way. Nothing sticks out or sounds out of proportion... it's very evenly balanced. It captures the dynamics, the full beautiful tone, and the timing of the music and presents it all in a very believable way.
The Aro has stayed with me for well over 20 years while the EKOS was sold off long ago. The Aro is a match made in heaven with my LP12 and my Benz Ruby S-Class Zebra wood moving coil cartridge.
I realize everyone has the capacity to "hear" things differently and have their own sonic preferences. But to "my" ears the Aro presents music in a natural and organic way in a manner that I hear when I perform in live acoustic events with my cello in classical settings and my trombone in jazz venues.
Best wishes to all,
