I'm looking to buy some non-vintage studio monitors that will reproduce the sound of acoustic piano’s, symphonies, and voices that are flat (or as accurate as possible with today's technology), and also whether or not I should sell my $9,000 integrated amplifier for active studio monitors with built-in amplifiers versus passive ones? What are the advantages and disadvantages with active versus passive besides having VU meters using separate amplifier with passive? I would probably require a subwoofer that could be used with studio monitors, but I'm just not sure where to go. I'd like to know what the "pro's" of studio's recommend (no B.S). I'm not interested in speakers that will resonate and cause vibrations on certain frequencies or give me some kind of "warm" feeling described with some vintage speakers. I'm only looking for the most life-like. My budget is anywhere from $1,000 - $12,000 (although I'd prefer to stay within $3,000-$5,000 because I don't think there is anything much better unless it's snake oil).
