I hope these photos will help other builders like me that find photos very instructive. I built these two this past early spring, after reading virtually every post on the forum, and downloading every good photo I could find and studying them. Most photos of 400s were not comprehensive, so I tried to emulate WOPLSniffers builds of 700s. So, here are my builds. All of my music is hard drive based or streaming, to a external DAC, then to a PL2000 preamp, then to a minidsp 2x4, driving the two amps, one amp driving 2 Dayton Audio 15" Ultimax subs, the other driving 2 JBL L150 Milleniums. The WOPLs are totally awesome, way more amp then I'll ever need, just totally FREEKIN awesome.
I want to say thanks to Joe for the incredible engineering and quality that he puts into his product, just top shelf. And Don, thanks for your DCP board, so nice to crank the music and know my expensive speakers are safe. So here are the photos, been doing some home renovation, so the boards are dusty, oh well.
