in addition, i forgot to mention...
Many musicians have heard of avalon and associate it with professional sound. many musicians also arent familiar with recording gear, for real, but "hey, i could do that.." whatever...
the fact of the matter is, online, you arent looking a person in the face and you dont know if they are BS'ing you or not. ask somebody for a recommendation- they could be some stupid 16 year old (like myself hehe) and they say "avalon 747sp is the best thing you can get for ....." and they say that because; a)its the only pre amp they've ever heard of, and b)its the most expensive one in the musiciansfriend catalog.
this forum is better though, most of the people on here really have experience with gear. i dont know about the rap forum, i've never been in there.
one trick i use to see how reliable a source (person) is, i check out there public profile. if they have a link to a home/pro studio that they run/work at, and they are a real deal studio, then i would take there advice seriously, after checking out there links of course.
i get turned on by pictures of studios, and mine isnt quite big enough yet, which is another reason i like to look at peoples studios...
but thats not to say that people w/o links to studios dont know what they're talking about, they just dont have a website/have a real job/whatever.
