Long time lurker here. I've started out on this hobby a while back, but up until I ran across this place did I find out more in such a short span of time.
I tried a few amps here and there but one place I'd warn against is the one on collins in tustin. toftt and will never recommend that place at all. Personally I stick with aamps as there is less BS, but that's just me.
Monger on.
