I think these are innovations for Clearaudio turntables, not inovations in vinyl playback generally. What new (for Clearaudio) we can find in Ovation, Innovation Compact and Innovation at first sight?
1. DC-motors (instead AC synchronous motors);
2. OSC motor control mode;
3. Sub-platters - aluminium in Ovation and solid stainless steel in Innovation;
4. The main platters are made out of POM (instead GS-PMMA / acrylic).
Several years ago Linn did the "innovations" #1 and #2 as well.
