Ridge Street Audio is my choice. I have both single ended and balanced models and have been very happy with both. There was a time when I preferred the one style termination over the other depending on how the music was recorded (intimate or large scale) but that preference changed after I auditioned Robert's latest RCA terminated model. It takes the best traits of both earlier configurations and blends it into a cable that sounds great with any style of music, no matter how it was recorded. It conveys a very large, cohesive sound stage (typically found in balanced designs) with the superior imaging of individual instruments normally associated with fine single ended cables. Note that we use similar digital gear. My digital set-up consists of a CEC TL1-X and Audio Logic's latest and greatest DAC. Also-I owned the big Kharma for 8 months or so and I prefer the RSA.
