The SilverFi cables are nearing break-in, aproximately 200hrs. During the breakin process I thought I had a handle on the signature of these cables. I do not. These cables make a difference by not making a difference. Its like no cables at all. They are virtually invisible. Music flows like a natural, crystal clear stream that brings forth MUSIC in its purest form. No additives. No deletions. Revealing, textured, dimensional, spacious, far reaching, dynamic, exquisite tone, airy, dense, neutral, and you name it, these cables do whatever the music ask faithfully. Absolutely, a must addition!!! I feel like I won the lotto by purchasing $300 tickets.
