I have just been comparing them to Missing Link Alaqeia (I'm talking about VD Classic Instrument cable which is typically used for hifi) and there is no difference to my ears - both are silver-plated copper. The ML have Eichmann bullets too. However, I have only ever heard subtle difference between interconnects (it beats me how you get people on here claiming to hear clear differences between say Chord Crimson and Cobraplus). The VD are a tenth of the price of the VD for same length. That either makes the VD Classic very good, or the ML Alaqeia very ordinary.
I buy interconnects used as the mood takes me, sell them on for roughly same, no loss, experiment to see what the fuss is about. The VD however you can buy new - they are so cheap.
