Looking for a reasonably priced good quality interconnect

I have an Oppo bdp105d and use Morrow MA6 with Eichmans. I found them used on Agon for about $500. They replaced my MA3s and showed a great improvement. Fantastic cables for the price new and a steal used if you can find them. 
The MA3s are still good, but the 6s are a big step up!
