MIT Matrix rev 60 speaker cables. Has anyone listened to them?

Go for it. Once you go MIT you will never look back IME.  And Joe is first class.  

Why are they only sold thru an Agon seller and not listed as a current offering on MIT web site?

Seems odd???

I have a pair of the Matrix 60 HD biwire. Just outstanding. Should be required equipment with Wilson speakers. I stumbled onto a pair at a great price so while still not cheap, made it easier. They really are like a significant component upgrade, though some folks here yell 'heresy!' and really balk at that notion. Depending on budget, I would also consider the Matrix 38. PM me if you would like more info.

Serious Question:  why aren’t these cables listed on MIT’s website and secondly why are they no longer offered by known retailers like @The Cable Co “??

They’re offered exclusively through Joe Abrams on Audiogon. MIT doesn’t promote these cables Joe does on his own website. I’ve also tried searching for any info on these cables, but there’s nothing out there. I’ve chatted with Joe and he seems like a real stand up guy. He has feedback over 1000 on Audiogon all positive. Like I said I’m looking for someone who has first hand experience with these cables. He offers a 30 risk free home audition and even pays shipping.
That being said,I don’t want to get them without any understanding of what they actually sound like. I know all cables are system dependent, but I still like to know if they’re as good as he says they’re. Might just have to find out for my self; at some point!
