I wanted to start by stating that I do not use a computer for DAW or mastering. I do not have a lot of money to get the latest, and also feel I do not need one as I can do pretty much anything without it anyway. I have an old iMac and its ok for somethings but not full blown DAW and one in the future with DAW and DAC would be nice, but I do not think it is absolutely a must have for me. So I get by with some gear and am looking for more as well because we all know that gear lust feeling. So I am not into hype and see most instruments as a way to express and make noise instead. And my set up is ....
MPC1000 + JJOSXL This is the heart of the operation like a few here. Takes care of the sequencing of everything else and also its a sampler as well

JJOSXL should have its own entry in my list but lets take it as a given
Korg D1200 mk2 A digital 4 track recorder. Everything gets plugged into this and i monitor and record through it all the time. CD player broke only yesterday after many years service, so pretty good.
Legacy monitors Reasonable monitors, though not enough bottom end, so sub is on the agenda. Cant make Drum and bass ect without being able to hear it right.
Roland Fantom XR a rack mounted multitimbrle synth plugged into D1200.
MicroKorg not a bad VA if I do say so. plugged into XR
Novation Bass Station Not a VA mono synth. very fat with some MIDI CC control plugged into MicroKorg.
outboard gear OK so now I got some stuff for signal processing as well. A Phonic PCL3200 compressor, which is very nice and another autocom MDX1200, a crappy Behringer compressor. Ok add a Phonic 32 channle stereo EQ and Behringer Virtulizer Pro FX rack and patch bay as well. EQ feeds side chain MPC goes through one compressor. sometimes i patch stuff differently and there is a hundred different ways I can do it, but just the shortest signal chain is what i aim for. I hae a few drum machines not plugged in. I think i might have started a collection with a TR505, SCI Drumtraks, MC303. O and dont forget the Korg Monotron as well for synth fun on the go
So there you have it. A totally hardware set up with no mastering or software involved. I just turn it all on and load a project that has saved patch changes for the synths so the hardware settings loads and is the same as when i saved it - neat. I use an old Imac sometimes for Fantom XR editing just cos its a very tiny screen on it and can be a strain to edit. So everything you hear from me is live unedited recordings that are not mastered at all. Yeah 16 channle mixing desk is next i think.
