Does Synergistic Research have a "house" sound

I am curious about these cables. It appears from reading the selection guide on their website that depending on the level (i.e price) of cable used, the sound changes. For example, going higher up the performance scale, the more resolution and going down the performance scale results in a warmer sound. So it seems SR cables all sound different depending on what product family is used. Do SR cables then have a "house" sound or characteristic that is common across all of their cables? Also, what is the sweetspot in the cable lineup? For me, the Sig 10 and Resolutoin Refereance is in the range I am willing to spend.

thanks in advance.
