well, the op asks the question: "does it take good gear?"
and that's a loaded question....
there are tons of anecdotal stories out there, of pros using 'less than stellar' gear to get their signature sounds.
but typically, the albums you enjoy listening to, were recorded in professional studios, with professional gear.
so, just because bono sang a tune in a hand held sm58......
or van halen bangs away on a guitar that cost him about $150......
doesn't mean they didn't use an extremely high end board and outboard gear to run all that stuff thru to mix it...
and i think guys that are just getting into recording, i mean really diving into it for the first time, aren't really sure about the limitations of 'pro-sumer' gear, and don't realize that for the most part, they really don't pass muster, compared to pro gear.
i'm lucky enough to have worked in, recorded in, a few pro-level studios, to get to hear the difference first hand.
and i've been engineering and recording myself and others, for almost 27 years now, and where i'm at right now, is that i use what i have, as good as i can, and i'm ok with that.
i can't afford pro gear, probably never will, but i still learn techniques from pros, and develop my ear, and all that.....
the point about 'good tracks' i was trying to make...
is that if you have a very nice mic.....
and a nice preamp......
and a nice convertor, either sound card, interface, or other....
you can learn to capture 'good tracks' in terms of sonic quality...
but as you said before, the performance will always trump the sound quality, unless it's just dirt poor recordings.
