You do realize the Benchmark will not pass the SACD through, right?
Yes, I would just use the Sony's analog outs for the few SACD's in my collection.
I switched to the Rega Saturn and have been happy. Looks like I went exactly in the opposite direction!
Actually, I owned the first generation DAC 1 and found it to be somewhat uninvolving; I ended up buying a used Sony SCD-1 for dirt cheap and liked it better. The system has completely changed since then, with a different CD player, different amps, preamp and speakers. The DAC1 is also not the same unit as it used to be either. I guess I'm curious, especially in light of the recent glowing feedback on the new DAC1 in TAS and elsewhere.
