Let me guess. You're one of those that think if the buy a UAD plugin the got the real thing and sounds exactly the same?
Why would I buy plugins that attempt to mar the sound with discolorations when I already have tons of built-in options to alter the sound with EQ, phase and other effects?
Audio gear shouldn't sound at all? Are you serious?
It depends on what you're looking for and where it is in the chain. It should NEVER change the sound in the playback chain in a system that claims any kind of accuracy to the signal as you are then modifying what is in the recording by altering it. On the recording side, it should be accurate as possible in the standard studio chain and only modified by the artist before being input into the system if they're looking for a certain sound.
In other words, if your goal is to record a live orchestra and have it sound as real as possible, the LAST thing you'd want is a stack of tube pre-amps between the microphones and the recording gear. If you have a rock band that wants that "tube amp sound" on their guitars, it's an artistic choice, not a question of fidelity. In short, I would not want this Apogee device imparting its own colorations to the signal. That is not its job.
Should I tell my clients to dump all their tube gear etc. because it doesn't sound transparent and therefor not real pro audio gear.
There's a difference between using something because you want to create a certain sound (e.g. tube amps create even-order distortion which sounds pleasant to the ear) and having equipment that colors the sound regardless of whether you want it or not (i.e. amplifiers in the recording chain that have nothing to do with artistic input or on the playback side where instead of recreating what the artist intended you to hear distort it by adding their own color). One example is the turn-table on the playback side. The reason some cartridges sound "warmer" than others is that they're changing the sound. Hey, if that's what you want, fine, but don't pretend it's accurate playback. It's no different fundamentally than adding a graphic equalizer on the playback side. If you want to crank up the bass or mid-range for a given album, go ahead but it's not what's on the album. Choosing speakers for a "warm" sound is the same difference.
The bottom line is that if you want to hear what's on the recording, be it the playback chain or the monitor speakers in the studio, you need ACCURATE equipment. Otherwise, you're making adjustments to adjustments and the end result on true high fidelity (as in accurate playback) equipment will be an unknown.
So no, I don't agree with studios that use cheap playback speakers because it's an "industry standard" or it gives a certain sound. That's a crock to any real engineer that wants accuracy, not marred sound. "Pro" unfortunately doesn't mean accurate and that's why there's a LOT of bad sounding albums out there (and I don't mean the artists' performance).
You might as well use plugins to alter the sound if that's what you're after since all you're really doing is changing the frequency response, harmonics, phase, etc. anyway. By all means, make it sound like you want it to for a given project, but don't tell me it's a good idea to use colored gear in the studio in general since you'll never have an accurate base point to start out with.
