I'm going to throw another recommendation out there. Try Audio Envy cables. They are unique in the market. They are incredible with electrostats! He has a 45 day trial period, so no risk except the few dollhairs of shipping. Ignore the less than stellar website. These are quality, hand-made cables with fantastic tech specs.
https://audioenvy.com/store/+1 I recently gave these a shot and am seriously impressed.I agree that the website will not inspire confidence in your decision,lol!After verifying myself that several customers did indeed put their much pricier cables up for sale and kept the AEs I had to try them.The ics by themselves are all about the midrange.The addition of two pcs(dac +pre) brought in the highs,bass,and dynamics.They are very slightly lean in my all tubed system,but so transparent,detailed,layered,and 'musical'.
