perfect timing for me too! I also have an RCD1072 and I'm looking into DACs. See my thread over at Tech Talk, where several people recommended DACs. I´m mostly thinking Bel Canto DAC3, Bryston BDA-1, Lavry DA10 or 11, Benchmark, Weiss DAC2. All of these are said to have excellent jitter rejection and were recommended by users knowing that I will pair it with a 1072. Actually Benchmark had a whole marketing campaign about the small impact the transport has with their jitter rejection approach. Can you audition, or are you buying used? Can you buy used and try? I wish I could, but I'm overseas and that's not practical.
Let us know how it works out for you.
