Ah, right - no idea about streamers or your speakers.
When I heard the Creek EVO 2 I found it to be punchy and detailed, although it does lack the Nads outright bottom end. It, however, more than makes up for it with bass strength.
Is there anything particular you don't like about the Nad?
If your after a taste of high end the Creek will fit the bill, but it will expose any weaknesses in your system. If something about your listening experience is bothering you don't blame it on the amp. Presentation is quiet dry but not thin or cold, if you after overblown warmth look elsewhere.
