MacIntosh has a very specific sound. They remind me of Harley Davidson... well, except they make high quality products. Also, like Harley, they look really cool... very masculine.
The sound is throaty and deep, with a strong emphasis on midrange and bass. They pair well with B&W speakers... which are a bit hot on top. Great for rock and roll.
But, as far as high end, they just do not have enough detail and balance to be included with the audiophile picks. So, companies like Boulder, Audio Research, dCS, Conrad Johnson, and contenders typically get the attention.
