I picked it up yesterday and set it up. The table was christened with Jack White's new album Blunderbus. Since the time gap between the old table and the new table was about 3 weeks long, I won't say that the Xpression III is a definate improvement sound wise over the Xpression II. I love the sound of the III but I loved the sound of the II as well. I did notice several things though about the III which build wise seems better than the II
1.) I can't hear the motor start to spin when I turn it on like I did on the previous model.
2,) The tone arm seems to be more robust than the previous model.
3.) The dust cover seems to be thicker and feel more rigid than the older one.
From a build perpective, I feel like its a step up. Sonically, it may be as well but like I said before, the time gap between hearing the old and new table is too great to recall accurately.
