The Aurender is a great streamer. Looking at mostly the cost of the Luxman Transport / DAC I would also think given the rest of your system a single purpose DAC (not transport also). What about the LUXMAN - DA-06 DSD DAC. This seems to be more in line with the rest of your system.
Recommendation for Dac for streamer
I'm thinking of replacing my current integrated amp that has a Dac with a Luxman 590 AX11integrated amp without a Dac. The seller recommended a Luxman D-03x CD player that has a Dac. I have Aurender ACS10 and Nucleus Plus streamers. Can those streamers use the Luxman Dac or should I forget the D-03x, and buy a really good separate Dac? I'm relatively new to this, and may not be expressing myself well.
