Cables do sound different. The open questions are:
1. Is the firms explanation real or marketing hype? (e.g. some kind of special construction). AND
2. Do these sonic differences really matter a lot, AND
3. Are these differences due to simple measurable characteristics such as impedence and capacitance?
I have heard, in extreme cases, one change in a pair of interconnects make a night and day difference in a system (adding Cardas to an extremely lean harsh system), but in general the difference is audible but not earth-shaking.
As for cable lifters, I tried them and did not hear a difference but I liked them so I used them for a couple of years, then sold them.
