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?

Desktop users longing to take advantage of ExpressCards on their machines have long since been quieted, but for laptopers looking to somehow stuff a PCI Express card into that diminutive slot, your prayer has been answered. Magma's ExpressBox / Express Box Pro allows users to operate a PCIe card up to 6.604- / 12.283-inches in length by handling up to 250MB/sec, providing dedicated power and cooling solutions, and playing nice with Windows XP, Vista, and OS X. The breakout box sports a fliptop lid for quickly changing out PCIe cards, and after installing the appropriate drivers, users will have full functionality of a PCI Express card right on their portable machine. Notably, these iterations only support cards that require 55-watts of power or less, and the company notes that gamers wishing to cram power-sucking GPUs into these boxes need to wait for the next revision before giving it a whirl. Even still, you better need the PCIe portability mighty bad to rely on one of these, as the ExpressBox and ExpressBox Pro will run you a stiff $729 or $749, respectively.
