Audioquest Comet input?

Hi folks-

I can't find a lot of reviews or comments on these speaker cables. Is anyone out there familiar or using these cables?

I am currently using Nordost Blue Heaven and have been for years. I started with these when I had a different level of gear and have done a pretty extensive upgrade over the years. I have moved and the cables barely reach my amp now.
Time to upgrade to longer lengths and upgrade in general at the same time.

I have the Comets coming in for a test drive in a week or so. Thought I would fish for some info while I wait.

I opted to try these as I wanted to start with a copper/silver combo first and see how it goes. Not so sure about DBS yet but I guess I will find out soon enough.

Any personal experience with these cables is appreciated. Just don't see too much info on the Flatrock line in general. The Blue Heaven have been a nice cable as I build up my system but time to try something else.

Thanks-
Rick
