That's a good start, paparazzi. When in doubt, always try to compare your mixes with a lot of playback systems. For example, I have a single Roland MA-20 that I set up as a mono speaker, it sums the left and right channels, for mono compatibility testing. I even burn cd's which I play in the car to hear how the mix sounds within the confines of a car's acoustics (they say if it sounds good in the car, it will sound good everywhere else, YMMV). MikeP has a short distance FM transmitter for checking how his mixes sound over an FM radio. There are many ways to check how your mix will eventually sound; if it sounds good over a variety of playback media, then you can rest assured that the mix will hold up anywhere.
