I use Audio Research sp16 with my Bel Canto REf 1000m amps and can easily recommend it for top notch sound.
REf1000m amps specifically have high 100kohm unbalanced (higher balanced) input impedance which makes them very compatible with tube pre-amps.
Class D and tube pre-amps in general are a match made in heaven, especially when amp is designed with higher input impedance to optimize the mating.
