Phono stage needs stable voltages for the small-signal to phono(line) level conversion. A turntable dictates the timing of the output waveform and needs mechanical isolation ...similar to a DAC needing ultra low noise to ensure the output clock is stable.
An EXPERIMENT for those who have never heard differences in cables
There are many here who have never heard differences in cables, I was there years ago until I read a post of someone preferring the sound of 28 awg magnet wires for speaker cables. I quickly drove out to my local Radio Shack and picked up magnet wires of various sizes (22-28 awg) to hear what it sounds like. I remember this being a fun experiment and a really cheap one that taught me a thing or two, I've gone on to experience many other cable designs over the years.
***Run two insulated magnet wire to each speaker (one for positive, one for negative) and use them in place of your existing speaker cable, the insulation on magnet wires are very thin and a little difficult to strip, sandpapering the tips may work. Connect them to the binding posts on your amp and speakers and let us know what you hear?
(Amazon also carries various sizes of magnet wires)
