The PSS Octets and the HGA Silver Lace (refered to now as the Silver 16 on HGA website) are both good cables. I had used the Octets for about a year and just replaced them with the Silver Lace. I thought the Silver Lace were smoother without giving up any detail, had a more open midrange and fuller bottom end. The Silver Lace were not bright at all. The PSS sound was more lean with less bass and midrange so could be perceived as "bright" depending on the system. Homegrown Audio has a 30-day return policy and I am unaware of any "restocking" fees for returns. You may want to e-mail or call Paul or Kevin to find out.
