I have Morrow MA4 balanced interconnects and was very happy with the improved sound in my system. My comparisons are limited so I won't make any claims that they are the best cable ever. I picked them up the last Black Friday sale which put the level of cable that I was interested in at a price point that I was willing to spend.
I did actually reach out to Mike via email to "challenge" his marketing strategy because I feel like it devalues the product. The constant sales essentially set the value at the lower price. Paying anything above 30-50% off is just a lack of patience. Mike responded that a lot of customers like to buy things on sale so that's the strategy they have chosen to take.
I found it very interesting that my balanced MA4 cables cost exactly the same as the unbalanced, but have double the internal wires so clearly the material cost is insignificant to the price point. I guess getting balanced cables on Black Friday sales is the best deal!
