The Scan Speak 9500 on your Carbon 7's drop off sharply above 15kHz. In other words, tt's not your gear. It's the speakers.
If you want to get a bit more 'bite' out of the treble, I would advise pairing the Carbon 7's with electronics that a bit more linear or even forward by nature. Since you are looking at integrateds in the M3 range, I'd also suggest investigating the Naim XS integrated, the Bryston B100 integrated, or one of the more affordable Sim Audio pieces.
