HAVE CABLES EVER TAKEN YOUR SYSTEM FROM SOUNDING JUST OK TO SOUNDING GREAT? Experiences ?

Wouldn’t say “just ok to great” but have been happily reacquainting with Cardas cables:

• Clear Reflection from DAC to pre
• Golden Reference from pre to amps
• Golden Cross from amps to speakers

Like most responders here, I hear subtle but definite changes from cables, although not to the level that would make a good system sound bad or a bad system sound good.  Since I have a box (or two) of cables around here, a change in cables is sometimes helpful to compliment a component change, subtly of course.

"Our Infigo Audio cables"

@calvinj - The wording above, your use of "we" and "us" in your posts, as well as references to loaning out cables and the "infigo cables demo program" leads me to wonder whether you have an industry affiliation with Infigo Audio?  If I missed that disclosure in this thread or in another thread, then sorry.  Also, it doesn't matter to me if you are affiliated but, if yes, that helps me understand the thread a bit better.

My experience remains that cables do not totally transform a system (i.e., from bad to great) but, at least in my recent experience, they can certainly add that final touch that changes the sound from "something's still missing" to "nailed it!"  

I have been comparing eight different sets of interconnects in a system that requires two pairs at 2M and one pair at 0.5M, all balanced - XLR. 

I have zeroed in on a set of Belden tinned copper cables, a set of Gotham copper cables, or a set of Cardas Golden Reference ICs. 

The Gotham cables are quite sweet sounding, the Belden cables are also sweet sounding and have a hard-to-resist richness and musicality, and the Cardas GR cables have great tone, depth, and punch, while sounding just a bit more rounded/smooth than the others.  I was surprised my reference Furutech u-P2.1 cables don't seem to be making the final cut, and I am also surprised to be finding it hard to put away the Belden 8402 tinned copper cables.
