The Rogue Audio M-180 \"Dark\" is a pair of these monoblocks. Each one uses a matched octet of KT120 output tubes to deliver 180 watts of tube power per channel.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0.9em 0; line-height: 1.55;\"\u003eAn external switch lets you pick ultralinear mode, for more power and control, or pure triode mode, for a more relaxed, harmonically rich sound. Both 4-ohm and 8-ohm output taps are built in, so the M-180 Dark can match a wide range of speaker loads. A \"slow start\" turn-on sequence protects the tubes at power-up, so they last longer.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0.9em 0; line-height: 1.55;\"\u003eThis is a power amplifier only. It needs a separate preamp, or an integrated amp with preamp outputs, feeding into it.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 1.25em; margin: 1.4em 0 0.35em 0; font-weight: 600;\"\u003eThe \"Dark\" Difference\u003c\/h2\u003e\n\u003cp style=\"margin: 0 0 0.9em 0; line-height: 1.55;\"\u003eThe M-180 Dark starts from the same amplifier circuit as the standard M-180, then upgrades nearly every part in it. Rhodium-plated Cardas binding posts and RCA jacks replace the standard connectors. Cardas internal wiring replaces the standard signal wiring. Telefunken and RCA small-signal tubes replace the stock preamp tubes.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0.9em 0; line-height: 1.55;\"\u003eInside the power supply, Hex Fred high-speed diodes and polypropylene bypass capacitors improve on the stock parts. Nude Vishay resistors sit in the circuit's most critical spots. The result is housed in a black anodized, CNC-machined aluminum chassis, available in black or silver.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 1.25em; margin: 1.4em 0 0.35em 0; font-weight: 600;\"\u003eWhat Reviewers Are Saying\u003c\/h2\u003e\n\u003cp style=\"margin: 0 0 0.9em 0; line-height: 1.55;\"\u003eReviews of the standard M-180, which shares the Dark version's core amplifier circuit, have been consistently positive. Erick Lichte of \u003cem\u003eStereophile\u003c\/em\u003e found that \"ultralinear mode played to the M-180s' strengths of immediacy and in-the-room image palpability,\" while Gary L.
