Point of diminishing return for a DAC

Get the Mac out of the audio chain. I use a PC to control a 2TB Buffalo Box NAS drive that has all of my DSD, MP3 and FLAC files connected to a router via Ethernet. The PC is on the same network, so it controls the downloads from sites like HD Tracks and Pro Studio Masters for my downloads that go right to the NAS. I can stream right to a Sony UBP-X800M2 Blu-Ray player that handles the streaming to a Sim Audio Moon 100D DAC. Output from the DAC goes to a Yamaha A-S801 integrated amplifier which drives a pair of KEF Q500 towers. Needless to say, the sound is pristine. I just listened to Herbie Hancock’s “Maiden Voyage” as 192k/24-bit FLAC and I can’t even begin to tell you how deep the soundstage and how warm the playback sounded. In essence, it’s the Moon 100D and the coax cables that make the difference. There’s nothing mechanical in the audio path so the audio chain is unhampered by the physics of moving mass.
