best RCA interconnects under $150

You might add a $79 pair of JW Audio RCA's to your audition list. I tried a pair about two months ago, taking advantage of their 30 day trial, and found them to at least equal if not out-perform a number of my other sanely priced favorites I had sitting around. My previous favorites are priced in the $150-$250 area. They break all of their cables in for you ahead of time, so it won't take you 2 weeks to figure out if they are going to be "keepers" or not. If you are like most audiophiles, you will end up trying dozens over the years, and it is helpful to not have to take a big loss on every pair that does not synergize with your system. Find some manufacturers that stand beind their products with a similar policy.

I have the Tad-150 as well and use the MA-1 interconnects from Morrow Audio - a true audio bargain.

I have tried quite a few interconnects which routinely sell in the $50 - $200 price range on the Audiogon. From my experience you would be hard pressed to surpass the performance of the Soundsilver trilogy interconnects for less than $200.

Anti-Cables...still my favorites

Take Five Audio in Ontario will make up a pair to your length specifications based on professional Nogami Deflex cable and Neutrik Profi plugs. I doubt they can be bettered at three times the price, if at all, not being convinced of the superiority of mega priced cables.
