Pani, can you please say the wires you evaluated before and after their cryogenic processing?
Thats an interesting question. Short answer is NO. I have not heard the same wire before and after cryo.
But its just my observation after hearing some of the very well known cables which use cryo treated copper and cables which are not cryo treated copper. Typically the Cryo treated ones sounded cleaner, more silent, blacker back ground, better separation of instruments (in fact much better) and smoother over all....but along with all this it took away some life from the music, the tones were relatively dry, the air around the instruments were lessened, I hear less nuances in the tones which make it sound smooth but flat and over all less real.
Silver does not take away life from the music but on all occasions it managed to alter the tones of the instruments to a degree where it sounded a bit mechanical and less body.
But I do agree that silver can sound very smooth, detailed, transparent and extended all at the same time. If you do not care for that little alteration of tone and timbre it can be a very musical experience. Audio Magic cables are great examples of good silver wire.
