Before you buy anything very expensive, buy some simple and cheap stuff until you learn how to drive it. It’s only my humble opinion, but for drums, even a huge amount of cash does not guarantee good results with drums. People often cite certain Drummers who got their killer drum sound with minimal kit, but the room makes a huge difference to success. You want a professional studio? As in one that will generate a full diary of paying clients, or one that uses typical professional equipment for your own use? They can be very different. The other thing is that having a shopping list of colours, brushes, equipment and canvas does not make you an artist.
i just had to Google weckl. I see his history, and I’ve looked at some images. Not heard anything he’s played on, but I guess he’s a drummer‘s drummer. Very clearly he records in excellent rooms. You could swap mics, interfaces, mixer strips and all sorts, let alone monitors, and still not sound like him without the room, and his touch. Like the guys who buy a Brian May guitar, processors and a pile of AC30s.
your acoustically treated room. Treated to do what? Not let sound out, not let sound in? Or to reflect, diffuse, diffract, absorb in a musical manner?
what worries me a bit is the quest you have set yourself. I think the first thing I’d do is put the kit in the room, set up one mic, a high overhead. I’d pick a wide band condenser and record ten minutes of quiet, loud, rock, jazz and your other favourite styles. Then you need to listen on something wide band and capable, in a know space, or headphones. Maybe use a CD like the Alan parsons soundcheck. The listen to yours vs his specially recorded drum. Once you know what it sounds like in your room, then, you have some kind of base line to help form choice.
the worst thing to do is to buy everything in one go, especially big ticket items. You have nothing to base decisions on. An SM57 is always a good purchase, but as for interfaces? Most people buy new ones when they don’t have enough inputs, or where their recordings are already awesome, but just lack a tiny bit of something. Good recording studios are always evolution, never good because of equipment bought in one go. A friend works for a large concern with a big equipment inventory and a nice ‘sound’. They’ve just opened another in a different part of the country and have even copied the space, not just the equipment. Already they’re buying extra because some kit just doesn’t sound as good in a space that in a photo could be mistaken for the other. Shopping lists for intro, smaller, projects can be done successfully, but until you have a pair of good monitors in the facility that sound good to you for your sort of music, you wont be able to judge the rest of the kit purchases. Sorry for long post, but I think you might just be about to waste a lot of money if you don’t take great care.
