The discussion thread for the product review has a long exchange on this topic, but I didn't notice a resolution. My D400ES replaced a Benchmark DAC3L and is connected to Nilai500 monoblocks, which are driving a pair of Dunlavy SC-IV/A speakers. The monoblocks are set to mid gain, 21.8 dB.
I've been using PCM Filter OFF, and normally have the volume set to around -25dB. If I use Linear Fast, the volume drops considerably, and I end up at about -20dB to compensate. I'm pretty sure I could pass a blindfold test during which I would choose OFF as producing a more convincingly live, dynamic sound. And, if not, then I can't distinguish between the two settings. Given this, what am I to make of Amir's rather emphatic assertion that OFF degrades the sound? Either he's wrong or he's measuring distinctions I can't hear. The discussion thread seems to suggest he got this wrong, but I can't find a response from Amir on his methodology.
Also, am I configured correctly to have the amps set to mid gain and thus the DACs volume quite low? Does it matter?
Between this DAC and the Benchmark it replaced, I couldn't be happier with the result. And, frankly, I was rooting for the Benchmark, because it's American-made.
