If you're big into do-it-yourself electronics, and feeling like your existing off-the-shelf pre-amplifier just isn't cutting it, Hack a day has the plans for you, with schematics and photos of a 7.1-channel pre-amp design sporting RCA, SPDIF, XLR, and USB inputs, and a VFD display to show you what's going on. The design is very professional-looking, and despite the glaring lack of analog tubes, it's sure to please any soldering audiophiles.
