The Benchmark DAC1/2/3 has dual digital and analog signal chains. This started with the DAC1 HGC, I believe. They're excellent DACs and I use a DAC1 HGC in one system with a DAC2 L in the other. I've moved on from other preamps because I can get all I need out the Benchmarks. Check their discountinued listing for factory refurbs - I saved a lot of $$ that way.
Cheers,
