Monitor selection
Monitor selection is not subjective! Is 2+2=4 subjective?
It's not what your ears tell you, how do you know that they are trained properly. What type of reference recordings do you listen to? How do you know what recordings were actually done well and which ones just sound good on YOUR system. What about your room? What is your power amp doing to your sound before it sends that power to your speakers.
SPECS! If they are true specs they will always tell the truth. First and foremost, FLAT Frequency response. Next thing to look for is phase response, which is basically the time alignment between the tweeter and the woofer.
Proper phase creates proper imaging. Proper frequency response creates a proper representation of the engineers eq settings and mic choice. The two combined, both being at a high spec, along with other specs like wide dispersion, low distortion levels,and high peak power handling, can lead you to a set of monitors that won't lie to you.
Then and only then will you truly be able to determine what sounds good, and what just sounds good to most people. Most recordings that people think sound descent, really suck. They are made on a budget, no attention to proper recording techniques, and mixed on car speakers. They sound good for the masses with the masses jam boxes. I am talking about speakers that can actually fool you into believeing that you are truly at a concert, as apposed to listening to a couple boxes. What is all the love with fake, boomy bass that only hits hard at one frequency and resonates the whole cabinet. That's what your cheaper "monitors" do.
MONITORS SHOULD BE TRANSPARENT. Transparency is not subjective. You can either tell you are listening to speakers or you can't. Either the sky is blue or it's not. A blind person may disagree, but does his opinion really matter in the world of colors? Then either does a deaf mans opinions in the world of sound.
Of course room placement is important when you are dealing with early and late reflections, but frequency response should not vary much if your have speaker is worth a darn and has fairly wide dispersion, especially below 500Hz, since sound starts to become omnidirectional below that frequency.
With a FAST computer, a descent sound card at 24 bit 96kHz, a good condenser mic, a good power amp; like a crown MacroReference, and an awesome set of monitors like the Timepiece 2.0's, a person can make a truly awesome recording and that is all that a person truly needs to make excellent recordings. You don't need every effects box or a million different mics or the best mixer. You don't even need a mixer,just a nice mic pre-amp. Except for a descent space to record in and , well..... something worth recording.
