I've been gigging lately at a smaller bar and need to buy a some small speakers, and a low powered amp to continue on there. (the guy that was running the sound is no longer able to do so)

I am thinking of buying a 200 watt amp for the power. I am looking for a really tight, bright sound match, with the philosophy toward the sound that less is more, and K.I.S.S. ( i.e. I am not trying to shake the walls or start a street dance while performing)

The guy that used to run the sound, had a mis-matched amp and drove too much power to his speakers, broke tweeters, fuses, starved the microphones with a cheap mixer and poor pre-amps and generally made the band sound like a big fart in a bathtub.

The instruments we play are all acoustic and the style is Bluegrass. I am looking for a system that is small in size. Has adequate but clear amplification, is lightweight, with balanced mics, preamps, mixer and properly matched speakers to reflect this.

Please advise

(especially on matching speaker size, as I would like to optimize the output in reguard to clarity)
