Like I said, "for those who care". I do not, frankly. But most 24-bit DACs do not approach true 24-bit performance, and 108 dB (18 bits'ish) or so SNR is more than good enough to me. I just don't find reaching for the absolute best in measurements the end-all be-all of overall performance; once past a certain level of performance, I look at other things. It is clear my threshold is lower than yours; I have considered getting an outboard DAC to try, but balked at the cost and effort.24/192 in processor seems like hype. Trinnov current dacs just do 18bits. Why even tout 24/192? Does not seem like that is a real advantage over any of the others when you look at how they measure. Just 24/48 is "drowned" in the noise of Trinnov's dacs.
FWIW, they've announced an upgrade to 24-bit DACs in the latest version, but I doubt I will pay for the upgrade. They also have an HDMI 2.1 video board but I don't need it so again will likely pass. When researching my SDP-75, I got to converse (via email) an owner of one of the first few units who has not upgraded and is perfectly happy. He was a calibrator so I considered him a credible witness.
You seem to have taken on as a mission in life to convince the world that Trinnov is not worth considering. You have made your arguments, reasonable and valid for the most part, perhaps it is time to move on?
