Speaker cables or AC regenerator?

Let us know if the AC device makes a difference... I for one am betting you'll be shocked (no pun intended)!

Tboooe, I have tried three kinds of power treatment on my various CDPs and
in every case, high, low or middle end the treatments made the units much
nicer to listen to. It just seems to me that digital gear is very much more
sensitive to AC crud than some people like to think. Although I have not tried
a power regenerator I am betting that the effect will be similar, and that you
will like it.

The only unit I have had that was not particularly affected by AC treatment
was my present DAC, an Apogee DA-1000E, which has an outboard power
supply of apparently very high quality.

The three kinds of treatment I know (apart from dedicated AC lines): premium
cords, filter caps across the AC line, isolation transformers. The differences
include soundstage size and dimensionality, clarity across the range,
transparency, microdetail, noise floor.

Measures to isolate the player from vibration are also very well worth trying.
