Among the under $500 silver ICs I tried the Silvers Laces were the most natural relaxed sounding, had the least amount of treble hardness/brightness while still providing additional treble detail and extension vs a similar priced copper cable. As I said I sold my $450 HT ProSilway II silver ICs once I tried the $190 HG Silver Laces. I have an all SS system which is very detailed, and need very smooth natural sound cables.
If your are trying to compensate for overly warm or rolled off treble you may prefer other silver cables that provide more treble energy but would sound bright in my system.
BTW although I have not tried an AZ silver reference IC, I am pretty sure I would prefer it to my silver laces if money were no object.
