I have been down the Mac/Dac route for about 18months, I recently picked up an old Teac P500 transport with clock upgrade and I love it, it sounds very natural through the same dac and I am using it more and more. It has a slight problem with miss-tracking occasionaly so I think the laser is on its last legs.
I have also bought an old Pioneer stable platter cdp for £50 which is being modified to clock link to my dac which the builder assures me will be better than the Teac.
So to answer your question cd will be the new vinyl.(and they are so cheap)
