We've seen all sorts of fanciful tube amplifiers over the years, but none have intimidated us quite like NAT Audio's Magma. This brute is the self-proclaimed "most powerful single-ended tube amplifier on the market," and it can churn out 160-watts at 4- and 8-ohms with a frequency response of 10Hz to 100kHz. Additionally, this thing weighs in at 88-pounds, measures 11.8- x 25.2- x 14.2-inches and relies on a 6N1P-EV, a 6N30P-DR and a Eimac 450TH tube to get the job done. If you're craving more specs on this Class A monster, we've got 'em: an input impedance of 100-kohms, input sensitivity of 2.7V RMS for full power output, gain of 22.5 dB at 8-ohms and a pricetag of $55,000 per pair. Check out a few more angles after the jump, won'tcha?
