Audio Metallurgy?

[blacsno]

Anything positive or negative about them. I've added a pair of GA-0 XLR cables, and RCA's. They replaced my Nordost Blue Heavens RCA. I admit I bidded on Audiogon and didn't pay MRSP. Well..... I was stunned how muffled the Nordost Blue Heavens, when swapped them back. Then I let the GA-0's break in after while, then swapped them out again. I thought the blue heavens were just choking out the MC352. Well those cables are 17yrs old. Yes.... I did do cleaning maintenance on them over the years. Either Nordost Blue Heavens are overpriced or not for Mcintosh "ducking". If Audio Metallurgy are that good how are they hiding under the radar? I'm thinking about getting them as speaker cables, but damn they are expensive!!!
