Drubin, You got me there.....this will be tough. Describing the house sound or character of any product is difficult. But I will try - and then think more after I post so I can describe it better if need be. I am not going to give you the standard audiophile terms of "air, transparency, detail, etc...." because I think that will be confusing.
One thing that really stands out with Kimber's products seems to be a certain unique way of defining the leading and ending edge of each note and the space between them. Kimber's products do this in a way that progressively gets smoother as you go up the line where as the lower end cables tend to have more dramatic (not exactly harsh) edges and the high end less dramatic and somewhat smoother. Low or high, the sound or definition created by this characteristic is unique to Kimber.
This quality gives a pace and a feel to the music which can be perceived as detail throughout the frequency spectrum because all notes (not just highs and lows) are somehow defined and split apart such that they become more visible.
This is similar to NBS in that there seems to be a blackness between notes because of the not-so-subtle beginning and end to each note but each note of Kimber is less abrupt and more rounded than even NBS's finest cables.
Climbing the ladder at Kimber gives you more organic sound. Lower end Kimber is stripped harmonically but higher end stuff - while still a little stripped of richness, sounds more organic, more natural more "skin-like". In fact the 3035 is THE most "skin-like" sounding cable I've ever heard through the mid-band.
To think of Kimber visually maybe you can picture a ball bouncing across a table... the ball represents each note in music...each bounce is between 1 and three inches high. The ball goes up in semi-steep round curves indicating it has energy as it comes off the table. Likewise the ball heads back to the table in the same curve.
Cardas "bounce" would be less severe... flatter, showing less energy coming off the table
NBS bounce would be more severe, coming off the table almost straight into the air curving slightly at the very top and then coming straight down again.
