LFD Mistral LE break in time?

Just purchased LE last week and not sure I want to keep due to being excessively bright. Could this be a case of not broken in, or is this the tonal character of the amp, thanks for inquiring?

Yes, let it run for about 100 hours. It'll sweeten up. Also, what is your cd player? I used to have a Mistral, and I really liked it. It was especially nice with vinyl. The thing that I have found with this amp is that it is very revealing of poor recordings. Power cord tweaks help, too--try the Audience Power Chord. I'd give it a little time before you send it back.
they do sound smoother after a while. best to leave it switched on all the time. i used to work for lfd by the way ! jeff
