Marcelo, My opinion (for what it's worth! lol) is if you can afford the MC-1201's, I say go for it my freind!
Different people have different goals, and strategies about audio equipment, and from what I gather somewhat about you, you wish to make a wise purchase decision, buy equipment that you are going to be happy with, and be happy with for a long time to come.
To me, even if I had Donald Trump's pocketbooks, I sure wouldn't want to be going through every flavor of the month, like I'm changing my socks, regardless of how much money I had.
I'd want to find something I can live with, be happy with, feel I spent my money wisely, and properly, and the bottom line is, the money spent satisfies me.
I've heard equipment that exceeds $150K in price. $33K Amps alone, not to mention the front end, and pre-amps-spekers that went along with.
I've heard equipment that perhaps impressed more than McIntosh gear in general at first, but I think most Audiophiles here will agree, Amps, and Speakers that are sharp, over-accentuated, and highly analytical can get tiresome very quickly.
My opinion is "what good is $150K worth of equipment, and it tortures you, that after 25 minutes you're fatigued, and want to shut everything down?
McIntosh by nature is generally very smooth gear, yet has never seemed to lack detail, and articulation.
Usually, it's the media one places on the CD Tray, or the Turntable Platter that has it's shortcomings.
One, I believe must always remember this, when placing a slightly beat up 35-45 year old LP on the Platter, and hearing shortcomings in the sound. One with wisdom always tries to "see" past this, and just enjoy the moment, and the music.
I wish you the best of luck my freind, and as far as McIntosh goes, I think this is still a company who is a first class contender, and worthy of anybody's home, no matter how deep their paocketbooks are. Mark
