Steve, have you compared the sound of your CD player to Spotify to vinyl for the same songs?

Also be aware that vinyl will sound like it has more body due to a recessed high end which accentuates the mids and lows. Vinyl also has more distortion and channel crosstalk which actually is quite pleasing.

It would be cool to have a vinyl simulator in the DSP.
