Hifiman5,I'm using Columbia xlrs also.I have not  compared them with anything else .I'm using King Cobra xlrs on a 2nd system.Both have performed well I think?At least I haven't felt the need to upgrade interconnects.I don't think I would spend more than I did on the Columbias anyway.Glad you got a deal from Music Direct,I've bought some stuff from them also.

@corvette01   I ended up choosing Colorados over Columbia due to more realistic bass impact and depth from the Colorados.

Hi Phil,
You really got a good price on those Colorados at half price! I think I mentioned to you once before I had the newer Earth interconnects. I bought a 1 meter pair of XLR's for the new price less 15%. I just bought a 1/2 meter pair of Earth with RCA's used, on Audiogon for $350. They are in like new condition and I felt I got a pretty good deal on them. That said, I would be willing to bet the Colorado's you have sound every bit as good as the Earth's. You got a fine deal on them. Congrats!!!
Tim

Thanks Tim!  The PSC+ copper along with FEP tubes and the 72 volt dbs system make for a fine pair of interconnects.  Enjoy.  Phil

Audioquest seems to make quality products but I find their lineup very confusing - trees, rocks, rockets. I have not purchased aq because I cannot understand what the differences are between the various products. Perhaps a good retail store could help but the website to me does not articulate what to expect from one line to another.
