@ghdprentice I have a newly purchased pair of 22 year old Sonus Faber Cremonas and with my McIntosh 2200 amp they can still screech when fed certain cds (vinyl seems to not be a problem). The older models may have a warmer tone, but they're still honest & occasionally unforgiving, depending on the amp you've paired them with.
I can't listen to B&W diamond series at all. The tweeter's natural resonance is 35khz, breakup frequency is 17.5khz so playing anything with cymbals or bells I'll get ear fatigue (if not intense ringing) in less than 10 minutes' time.
