Have experience with the MAS GRAY interconnect?

Stu Wein's service and reputation are first class. I have completed two transactions with him and the service is very satisfactory.

For $60 why not just try them? Stu is friendly to deal with, and communication and shipping both happen very quickly.

As for the cables, my impression is they are fast, revealing and detailed. I'm not a cable junkie, so I can't help with comparisons to any expensive ICs. (They replaced AQ Corals.) I don't find them harsh even with my rather modest solid state equipment (Carver AV-705, Sony DVP-NS900, MF A3/24, Dynaudio Audience speakers). (Maybe speakers with a more finely etched high end than the Dynaudios would push them across the line into harsh?)

Who said they were harsh?

I don't think anyone said they are harsh. What I believe was said is that they won't help a harsh sounding component like some digital stuff sound better (ie, act as a filter).

I'd say this is a compliment. The cables reproduce faithfully what source they are given..

Perhaps I should have said "bright" or "piercing" since that is what was said above, rather than "harsh". Anyway, they are none of those things on my system.

I agree with what Sugarbrie says above.
