Behold the iMPAMP

At a mere 4.4" x 3" x 3", the 1W per channel iMPAMP from Z.Vex is the world's smallest vacuum tube stereo power amplifier, and quite possibly the coolest $525 iPod accessory ever made. Not only is it a zinc-plated blue-glowing DC-coupled (no capacitors!) thing of beauty, it delivers a frequency response of 10Hz-20kHz +0/-2 dB at 8ohms, measured at 70 mW - with adjustable trimmers, to boot (-20dB for iPods up to +4dB for recording studios). You can order one direct, or find it at select retailers (such as Guitar Resurrection here in Austin) - but it's a limited edition, so grab one while you can.
