Reasonable high end interconnects: without breaking the bank

My guest coppertone black cat and acoustic bbq are my choice if I have to audition ic, both Teajay and Bill are season audiophile with good ears...

Nerve Audio cables are about $100/meter. Very well made and excellent conductors.

I go with a couple of users who mention Morrow. The most obvious difference from any other cable in that range that I can attest to is an amazing sound stage with excellent inner detail. I also need to stay away from extra "brightness" as my system provides enough of that and the morrow cables have that "extra dimension" in the tereble range with things such as cymbals. The "sweet spot" in their line are the MA-4 series. The improvements are not quite as great above that, although the MA-6 speaker cables I use are amazing. At regular prices I would think twice, but they almost always have a 40- 50% off sale. 
Analysis Plus Ones (yeah, the purple cables) are also very good and a relative bargain.

In a private discussion, one of the members told me that he replaced some $$$$ Verastarr foils with Audio Envy cables. I am trying to find more information on these cables.

Have slowly upgraded RCA cables
