Macintosh is a well respected and loved company by many folks. Their equipment is very well made, looks cool, and retains its value well.
It is not remotely neutral sounding. It is very heavy on the midrange and bass and is excellent for systems designed primarily for rock music… to thunder and hit your chest with bass. But not to come across as harsh… hence extended midrange. But it lacks detail. I consider it to be the muscle car in the audio world.
I have multiple times over the last decades decided I loved the look so much I was going to invest. I would go to the dealer and audition whatever the latest was. Each time, I would within seconds be so disappointed with the sound quality. No nuance or detail of a natural sounding soundscape. Lacks sophistication and detail. I have a dealer / friend that carries it now. I frequently it is playing. A few years ago he was excited to say that, they had really improved and have a more well balanced sound. I got very enthusiastic. It took ten seconds of listening for disappointment to overcome me. This does not mean you will have the same reaction. As I said, many people love the sound. It has unique strengths. It does what it does really well.
Let me reiterate… you put this stuff with some big B&W speakers and it does rock as best as it can be done and Blues You are just engulfed. With the accentuated bass and mid-range you can turn it up loud without the treble being uncomfortable. Great sound for this music. But for jazz, classical, etc. it really lacks the finesse, nuance and balance.
Do not think I am someone that is into systems that scrape details… I am not at all. I want natural, musical sound reproduction, with details in proper proportion… and especially musicality. With over ten years of 7th row center at the symphony and another ten years finding every opportunity to train my ears to what real venues music sounds like, I really do not like “the high end sound” of overly trebly and bassy sound so that triangles and cymbals become solo instruments and the guy plying the cello that moves his foot sticks out. Hence I slowly zeroed in on the equipment I have to be faithful to natural sound and make all music sound great… yet be forgiving.
