In no particular order...
- Get your room properly acoustically treated and set your gear up properly within it.
- There is no such thing as a neutral, transparant or flat loudspeaker. Use a CD with pro tracks that you are intimately familiar with and that sample well the style and genre of stuff you want to work with and use that to test the nearfields in your budget and see which "sound right" for your ears and tastes.
- Spend the greatest bulk of your money on quality preamps and A/D converters. They will make or break your tracking, and your tracking will make or break the rest of your production. Limit your signal chain to just those two devices when possible, adding to the chain only when absolutely necessary.
- Study and practice, study and practice, and then study and practice your miking technique. The better you are at that, the less crap you'll have to throw in your chain to try and correct for bad technique down the road.
- Get your gain staging all the way up and down the signal chain correct. By driving your gear at the voltages it wants to work at the best and by getting the right volumes for your signals you minimize coloration from the equipment you do have in a couple of ways.
