nice set of speakers that truly reproduce what is given them. i have had two amps on them and it was a very different experience with both, so the speakers are to be commended. went from 60 watts class a (cec amp3300). to a 100 watts given by the yba ya201. they do seem to have a sweetspot of volume that is a bit louder than most (high 80's to lower 90's spl). also play with the front spikes as they raise the soundstage considerably with adjustments. most of all enjoy the music, so easy to lose that as the reason for all the effort. happy listening.
