Did anybody use a Straight Wire Virtuoso R I/C?

I am using a Straight Wire Virtuoso R interconnect with my Cary 308t CD player, SLI-50 and SLI-80 integrated amps.
Initially, when used with the CAL CL-15 CD players (both balanced and unbalanced modifications), this cable gave a very odd impression. Before that, I borrowed from a friend a Virtuoso "Gold" interconnect and I liked it so much that I ordered its new version, Virtuoso R, without prior auditioning. However, I was disappointed because it sounded very harsh and bright, as opposed to the older "Gold" cable.
After a couple of months, however, the sound of the Virtuoso R changed for the better. It is well-focused and has a very powerful and controlled bass. It is especially good with jazz and classics (harps, violins, and pianos). What it lacks, however, is airy highs.
Did anybody have experience with this cable?

Thanks in advance,
Alexander
