Hi,
There is no reason you can’t get good quality sound in a non studio setup. As a recording engineer come film maker, I don’t alway have access to a real studio. Your equipment is good, just try to acoustically dampen you room as much as possible (sonex, cloth cover fiberglass filled frames etc.). Record close to the mic to reduce room sound. Record at least at 48k, 16 bit, WAV. Use light compression (2:1 ratio, 3 – 5db gain reduction, auto level -3) will tighten the sound nicely. The Soundtrack pro compressor works well.
