From Ken Rockwell's site:
"My McIntosh MC240 is the best power amplifier I've ever heard. While most great amps do nothing to alter the sound (what comes in is what goes out), and when transistor amplifiers alter the sound it's almost always for the worst, the subtle things tube amplifiers and especially the MC240 do to the music make it sound absolutely fantastic.
Of course the MC240 sounds completely lucid, fluid and detailed as you expect from top-end tube amps, but what you probably don't expect is that it has bottomless bass thanks to its huge transformers and special patented design that offers low distortion and flat response down to 3 cycles! My MC240 has better bass response than many of today's preamplifiers and power amps, along with the astonishingly lifelike midrange and a high end that simply shimmers.
No other amplifiers have McIntosh's Unity Coupled circuit, that along with its huge Bifilar-wound output transformers, lower the distortion to the lowest levels found in tube amplifiers. This unique circuit cross-couples the two 6L6GC output tubes into such a tight a lover's embrace that they operate as class-A at the most important audio levels. The circuit is so linear and independent of tube characteristics that it plays at low levels even with one output tube missing!
The McIntosh MC240 is McIntosh's first stereo amplifier, and their last new tube amplifier design before they gave up on tubes in favor of transistor amplifiers."
