You are probably the first person I ever met who actually likes them.

NOS ones appear on Fleabay occasionally. If you want to stay with that sound, watch there for Radians. I have seen NOS Radians at about half price, All things come to he who waits.

IMHO the Radians are flatter and go a little higher than Symbiotik. They are an outgrowth of Emilar/Renkus Heinz tech. Renkus was ex-Altec.
