I use an Ayre DX-5 DSD with balanced analog to a KX-5 Twenty for stereo, HDMI audio to a Bryston SP3 processor that sends balanced analog front LR to a by-pass input of the KX-5 and surround to a pair of NAD C288 amps. HDMI video from the DX-5 DSD goes directly to the projector. The sound is superb as is the Anchor Bay video the DX-5 uses.
