I have a pair of circa 1992 Sony PCM-7010F DAT Recorders, mostly a novelty these days yet I keep them since I have no doubt recordings I make on them sound more lifelike than any other means to recording I have. I used to use these recorders to master radio commercials, which were often copied to CD. Now listening to those CDs via DACs in Sony CDP-601ES, Sony DVP-S9000ES, and OPPO-205 Players, or from a Sony UBP-X800M2 Player to a Marantz NR1200 Receiver or Parasound P6 Preamplifier, I sense a loss in fidelity. At any rate, commercial CDs played via any of my players all sound the same. Kind of moot though, since I rarely buy CDs now that Apple Music satisfies so nice when played to Parasound P6 via usb.
