Here are a few pictures of my Balanced Line Stage/Pearl combination preamp. The Pearl is built with the Pass DIY printed circuit boards, while the BLS is built point to point. The second box is the external power supply. The cases were cannibalized from previous projects - which give it that look only the guy who built it can love.

As for the sound, what can I say that hasn't been said already? Both of these amplifiers are astonishingly good. I recommend both of these preamps to anyone who wants to build their own great sounding gear.
