assuming someone else is paying for acoustic treatment (and if not, budget some money)
As someone who owned a Control 24... no, you really don't want one... the pre's are crappy and they cannot be bypassed
The Euphonix control surfaces are great- If you want an analog board- the new Mackie looks good and will interface digitally
I do not see the justification for PT HD- if you really want PT go with 9.0. I'm now using Digital producer, great platform oin par with PT (IMHO) but the users forum has no patience for novices or poorly worded questions
as ProTools is now a non-proprietary hardware software-
RME FireFace 800 (I'm biased, I have one)
or one of the Appogees or Prisms
I would also look for straight A/D and D/A converters for the optical ADAT I/O's- why- I think (IMHO) you're much better off having separate pre-amps, rather than internals (The RME has 4, how are they... couldn't say... I've never even tried them) , unfortunately most internal pre's are not
pre's- there is a reason high quality pre's are $$$, they're very transparent ( and another bias as I do have a Prism 4 channel... tops!)
however, I like the coloration from the not so $$$
Bellaris tube and pre's and channel strips, Aphex, Presonus, Focusrite ... and I'd suggest immediately replacing the stock tubes (IF tube pre's) with NOS JAN RCA's, Mullards, GE, etc
compressors- Manley, UAD, Bellari's tube pre, is phat... a bit dark, but it has it's uses, and if you can find the older Altec Lansing compressors, very cool
EQ, at least a few whether 4, 7 or 31 band... your pref) , a para EQ
mics- I think there's quite a few reasonably great mics between $500 and $1000- I do like the Oktamods (Michale Jolie)- get a matched pair of LDC,s SDC's and a few of the workhorse SM57's (the Granelli rigght angle SM57 is great for snare)- on the lower $ the MXL 603c Mogami's are great and there are omni capsules available and a sweet cap mod that if you're good with a soldering iron can be made for not much $-
patchbays- really put some thought into this- if it's a PITA to change signal paths, you'll find you that you'll begin to ignore perfectly good gear
and I'm sure you've now long since run ourt of money LOL
