Arsh:
I am using Empirical Design ICs throughout my system and have for some time. I have tried several different cable brands over the years but have retained the ED cables because of their superior sound quality, flexibility and cost/performance ratio. Karl has also routinely provided me with custom lengths as I have relocated components or swapped in new gear. Not that it matters much but they won the TAS "Golder Ear" Award two years in a row back in 2010-11 (I think). That said, I tried Keith's cables at one point and found them very competitive with the ED cables (and less expensive to boot). They are a great value for money.
