I moved from an Origin Live Resolution MKIV with all factory upgrades to an older Basis Audio Gold Standard vacuum, with Graham 2.2 arm (via a Feickert Woodpecker/Kuzma 12 VTA), and the Basis vs Origin Live argument presented above is silly. Two very different designs with very different presentations. The Origin Live is detailed and airy and very resolving, the Basis has just as much detail and air but launches the sound from a rock-solid foundation with incredible bass extension. It has a more live or life-like feel, everything is underpinned by a solid, taught low-end.
The vacuum system works great. Support is fantastic via Alex at the factory. I'm thinking of moving to a newer Basis to see what developments have been made over the years.
