Difference between CAT JL1 limited and jl3

what are the dif. between these two amps-For the money are you better off with a used limited or a new jl-3- thanks K
My closest hi-fi buddy owns the Limited Editions. I will have him e-mail you.
One difference is that the JL3, which replaced the JL1, uses Teflon circuit boards.

An earlier response I tried to post was not posted because it contained a warning about a seller. Contact me for information.
