I just don’t want to spend more time preparing to listen than actually listening.
Me neither. Who does? I typically clean an album once, use a brush before each play, and keep my styli clean. But you will want to fine tune your set up, play with various cartridges, etc., hence my statements about tools and activity.
To your Clearaudio question: I owned an Innovation Wood with a Universal arm for 18 months and never really cottoned to it, finding it somewhat hard and thin. I didn’t like the DC motor being built into the support pillar, either, as it was noisy and clearly audible on the armboard through a cheap stethoscope. I replaced it with a Brinkmann Oasis, which is much better, IMO. Each on a Minus-K. I did like the Clearaudio’s capacity for two arms, though (my other was a Phantom II, now a Supreme in use on the Oasis), and it was speed-stable.
