Interesting. I felt my LMII spanked the living bejeebers in every way out of my M500, much less the 300 (which I have not heard... maybe its a better head than the M500, which is just awful IMO regarding tone/volume/weight/price ratio). I guess we all hear things differently
I agree with you though, the build quality of the PJ heads, even though I find the performance unimpressive, is quite amazing (which I guess is why my M500 weighed a TON!). It was beautifully made though... knobs, case, everything.
I have not played that neo6 or 8 yet, and those look pretty cool. The non-neo cabs are quite unimpressive IMO unless you get about 200 pounds of them
