Yeah, I really lucked out, but was sweating it for a bit.
I once picked up some fake tubes on fleabay, that was a hassle.
Anyway, I've been using my PFVIII's whenever I get the chance. Just got the DX50 today and I do have to say, they seem to have a better organic mix than with the X3.
The PF's really sparkle with the DX50, perhaps they like the more neutral but slightly thinner sounding DX50 over the richer,darker and thicker sounding X3?
