Re: Best Amp/Pre-Amp for Wilson Duettes
I would recommend you try some of the new switching amps (Bel Canto/NuForce/etc) before you buy anything. They are very good.
Most of these companies offer in-home demo's or at least a generous return policy.
I don't have direct experience with Naim but $12k can get you one helluva nice system.
Don't get fixated on the wpc rating - it tells very little about how the amp will work with your particular speakers and ultimately sound.
I would start by calling Wilson and asking them for some recomendations.
