NAIM: What to do after becoming dismayed by its sound?

Grumbling women

The thread starts: Hi guys. In the past I've had Naim Nait xs integrated amp along with a Naim dac. To be honest, I really got to dislike the sound. It had too much treble, or maybe thinness, to describe it in the most communicable language I can think of. Just wondering what amplifiers may offer a more lush warmer sound? My speakers are B&W CM9s.

Thanks
