Bob, The Tara labs Cobalt with oyaide terminations turned out quite good, I am satiesfied, during break-in, the cable had exagerated bass and a some brightness to the mids and treble, man has that all went away, I have learned you have to keep power going through the cobalt atleast a couple hours a day to keep it sounding great, if you leave the cable un used for two or three days, it will begin to sound un-burned in again, very strange, takes alot longer for all my other cables to not sound burned-in, like a couple of weeks or more, now, The Tara labs Cobalt does sound like a referance power cord, the bass is very defined, deep, and super fast, you can here music you never heard on your recordings before, the treble is incredible, the mids are too, really a very good balanced tone cable to say the least, clarity is top shelf, foremost, this power cable is lighting fast with slam!, not bad, since I only paid $1,000.00 for this 3ft cobalt with oyaide terminations, the terminations I discovered gives the cobalt a smooth warm sound to it, helps equal out alot with the extreme resolution, cheers.
