* Originally M150s-Upgraded to M180s by Rogue's Mark O'Brien himself at their Pennsylvania factory. Configured with KT 120 TUBES, with two extra tubes available. 150 per side Ultra-Linear 85 per side Triode.
Power, Grace, and Precision -- when you are ready for the ultimate in vacuum tube amplification, look no further than the Rogue Audio M-180 monoblocks. With 180 Watts of pure tube power, these monoblocks stunningly accomplish the impossible. After drawing the curtains aside on a soundstage of full height, width, and depth, the pace, and musicality of the M-Series provide a riveting performance that will leave you breathless.
Each Rogue M-180 is based on four Electro Harmonix KT90 output tubes. The M-180 can be run in the more powerful ultra-linear mode, in which it achieves its claimed output of 180W; it puts out less juice when run in triode mode. You select the mode with the flick of a switch at the back of the amp. Tube biasing is easily adjusted by hand with four switches and a built-in meter, M-180 has 4 and 8-ohm taps, and RCA and balanced inputs.
Its thick aluminum faceplate (I got mine in silver) has a circular cutout for the power switch and a glowing blue LED to tell you it's on.
The Rogues excelled at throwing a huge, well-defined soundstage with outstanding spatial separation between instruments. The Rogue M-180's control of low-bass notes was exemplary, with great speed and heft
The M-180s offer higher resolution, better bass, and a more defined stereo image than the M-150s.
