I forgot to mention how the VPIs sound versus Clearaudio and SOTA. Aries 3, Avenger Ref. They’re darker sounding. Especially with the 3D and Fatboy arms (I honestly liked the late make metal unipivots). There is a bass-reinforcement effect that can be fun, and some like. In my setup they were extremely reactive to feedback in audible bass frequencies, say 60 - 120 Hz. I think this is part of their sound. The CA Innovations can be reactive in the subsonic range (woofer flapping), due to the magnetic "float" bearing, but are SUPER clean and quiet through the audible specturm.
I think this is why VPIs pair well with Van den Huls, which have super clean bass, a lot of HF energy and firehose of details. With Colibris you can find yourself staving off sibilance, but Crimson & VPI was a really nice balance. I still ended up liking the metal uni better, but see why some like the Fatboys. The plain 3D arm, ugh I hated it.
