Anyone using Classe with Tannoy?

[Cornholio]

Do you think Classe 600 monos will be a good match with Tannoy Kingdom 15 speakers? McIntosh 452 fails to drive them at all. I'm told that the impedance goes all the way from 8 down to 3 Ohm, B&W style so the speakers need some serious doubling down amp. Also the Mac system (1100, 500, 452) sounds way too soft and sweet with Tannoys. Keep in mind that Tannoy Kingdom 15 is not the Prestige line - it has a separate woofer and can rock real hard with the bass that is unbelievably deep. But with Mac the bass sounds loose and slow.
