I am dying to order one of these. I just have to wait to clear up some tax issues- but as soon as I do I am getting one. I actually have only heard the Raven AC at Highwater Sound, and will probably go back to hear the Raven One, but thanks to Aoliveros comment, I am confident that the TW Acoustic is on the right path in terms of materials, bearings, etc. It's also a size and weight I can manage. I did like the sound of the AC - but honestly I think tables are almost impossible to get a handle on in a foreign system - different arm, cart, phono pre. That is one area I will give digital playback - as I think it's more consistent across varying systems. I suppose one could compare a reference CD on the foreign system for a while to attune ones ear to what the system is doing, the listen to a reference LP and try to extrapolate.
I have a Schroeder 2 sitting here purchased from A'gon, that I am dying to listen to, and can't mount on my current table.
I even emailed Frank Schroeder to see if he thought it was a good combo, and seems it is.
