Hi Misternice, I listened to the Tara Labs Cobalt power cord for a couple of years on different systems before I decided to buy it, I have not used it on my system yet, I believe I will with-in the next two weeks, this power cord will not sound special at all untill 150 hours of playing time, then it gets way better at 300 hours, then small, but noticeable improvements all the way to 600 hours,However, when you get to 300 hours, LOL!, you will not care, the sound is very satiesfying at this level of the burn-in of the power cable, one thing you need to know, I will be useing my power cord on the digital player to excellent effect, it will work great there, however, Tara labs said this power cord works best on pre-amps and power amps, if you get one of these power cords, get the cobalt power cord with the oyaide terminations, it's worth the extra $450.00 ,, it sounds way better than the cobalt with the stock watt gate terminations, make sure you do not get one longer than 6ft and you will be fine, if you can use a 3ft power cord, this will have more resolution according to Tara Labs E-mail to me when I asked if there is a difference in sound with different lengths, I look forward to your reply, cheers.
