What's that got to do with anything?
I will go out on a limb and say that 99-out-of-100 "fully pro studios" have engineers that know 100 times more than 99-out-of-100 guys on any home-rec forum know about engineering...
...and 99-out-of-100 pro engineers probably won't be working with your gear list (as good as it is).
You can make up all kinds of "what if" senarios....but you have to consider *what is* reality.
So...what "pro engineer of your choice" is going to come record an album with your gear in 5 days...?
I'm not trying to beat down your expectations about your gear. I use to play the same mental game back in my early days..."
what if __________ engineer came to my studio, would he be able to record well with it, or would he chuckle and walk out"...but after all these years I've accepted the fact that pro studios are a cut above, and pro engineers are also a cut above....and we're all just trying to measure up on at least some levels, gear-wise and experience-wise.
I got a ton invested in my studio...and I STILL don't think it measures up to *pro studio* standards....but I keep working on it. AFA experience....it too is a never-ending quest.
I agree with what you're saying for the most part, but I think the gap between pro studios and home studios is lessening all the time. And I'm not even talking about people having really expensive crap in their home. Maybe it has to do with a change in expectations from listeners, or maybe it's just that, as home recording gear became more affordable in the 80s, ever since then people have gotten better and better at using it. Since the digital/plug-in revolution, that's even accelerated (in some instances).
My point is that is a very real possibility now to produce an album in your home studio that sounds fully professional---no "pretty good for..." disclaimer needed.
Take for instance the band Midlake. If you've never heard of them, go check out one of these tunes (or both if you'd like) really quickly.
Midlake - Balloon Maker - YouTube
Midlake - Roscoe - YouTube
"Roscoe" sounds a little more "hi-fi" because they were going for more of an indie/lo-fi sound on their first album, from which "Balloon Maker" is. The second album, with "Roscoe," was more traditional in its approach.
Anyway, Midlake are from Denton, TX, which is where I went to school. I've met a few of the members, but I don't know them personally. However, one of my good friends does, and he told me in great detail about their recording process.
Both of these albums were recorded completely by the band in their home studio on a Roland VS-2480. They had one Neve preamp,
a Fatman preamp, one MXL tube mic, and one AKG C414. Other than that, everything else was pretty pedestrian regarding mics and pres. Almost all of the effects and dynamic processing came from the Roland---the only exception being a Yamaha SPX90 for a few special reverbs. I think they had an RNC too. They were in the middle of recording their first album (
Bamnan and Slivercork) when they got their deal with Bella Union records. They mixed it entirely by themselves in their home, and then it was mastered at Abbey Road. The same process was used for the second album,
Van Occupanter.
I don't know about you, but I think the songs sound great, fully professional, and plenty of other people too. In fact, "Roscoe" showed up at #90 in Rolling Stone's 100 Best Songs of the 2000s list:

So, the whole point of my question is trying to get at the fact of ... when do we reach the point where our experience --- not our gear --- is holding us back from getting pro-quality sounds? Obviously, "pro-quality" is subjective, but then again everything with music is.
