Ok. here's the situation: I've had my Trace AH-300 on the road with me since 1990. That alone says alot for the trace. No real repairs (just maintenence) and it's been great. It is however time to move on. I've run across an Ernie Ball audiophile 500. i've never used one and am curious if anyone here has any experience with it. I like the idea of separate eq'd switchable channels. Of course in a perfect world I'd be going WW ultra. But in this the actual world of money and whatnot that's going to have to wait. PS. the EB is selling for $500. Any thoughts?
