I agree pretty much with what Mr. A. said.

(Sorry Keith I couldn't resist)
I have personal experience with replacing the heads on a Peace snare drum owned by fellow DC'er dl,
Tremendous difference in sound after putting an Aquarian Satin Texture coated batter and Classic Clear snare side head on it(replacing the low grade stock heads). Of course it needed to be tuned up -which I have experience with - so that may be a factor in getting it to sound good.
Buy the
Aquarian Snare Drum Tuneup kit and you'll get the heads at a discount as well as a free video and instructions on how to tune a drum.
I think you'd do well to try one or two drums like rca said and see. I think a good drum sound is very doable.
