I have a McIntosh preamp and power amp, love their equipment, but feel that "digital" is not their strong point.
I have had a PS Audio DirectStream DAC since it was first on the market, and have paired it with their DirectStream memory player, interconnected with an HDMI cable (their I2S interface)...and a P10 PowerPlant (AC power re-generator). It is the best sounding digital I've ever auditioned!
