ryder - totem speakers are anything but bright. you must have been driving them with not very good electronics. i have owned/currently own 5 different pairs of totem speakers (from the arros, model 1's, in-wall taw, and a couple of pairs of mani 2's) all driven by very nice equipment. if you drive any totem with small amps or amps with no power they will sound terrible. they are dull, thin sounding, and maybe that is where you get the bright sound from.
the forest would be my pick out of the 3 you posted. they are easier to drive and would be more suited with your 100 watt mcintosh. the proacs are decent but i didn't like them as much as the totem or usher. if you are looking for a better deal,look into the totem hawks. not as easy to drive, but $500 cheaper used and are very close to the sound of the forest. some like the hawks better, it would be a toss up for me. if you are going to spend up near $1800 and you might want to get a more powerful amp in the near future, i would spring for the mani's. blows away the 3 speakers you listed, but needs at least a good 200+ watt amp with power to it.
