I've got a pair of speakers I modified several years ago to add a dome tweeter crossed over at about 13kHz. Ran them on a Lafayette LA-375 amp for a few years and most recently on an Adcom GFA-545II amp.
As best as I can remember the Lafayette has a flat frequency response to 20kHz based on testing I've done and the spec for the GFA-545 is down by .25dB at 20kHzs according to the specs.
Why did the speakers sound better in the treble on the Lafayette, but not as good in the treble when run on the Adcom?
I would have expected the Adcom to sound better given it's newer and uses a better circuit design, but that isn't the case.
I've never heard this much difference in sound between two solid state amps with the same speakers.
EDIT:
In a way the adcom almost sounds too flat like some of the silver face Yamaha receivers do.
