I recently made a firmware update on my Pioneer VSX LX503 AV Receiver and now native Tidal instaled on it plays full audio resolution, different from the boring 44.1kHz/16bit that it showed before. Once it does not support MQA, it does not unfold to higher resolutions, like 96kHz and 192kHz. But the sound quality gave a great improvment. Amirn commented when reviewd the VSX LX504 (
https://www.audiosciencereview.com/...d-measurements-of-pioneer-vsx-lx504-avr.8862/) .... "Also disappointing is that the internal processing is stuck at 48 kHz. I would have wanted to at least see 96 kHz there. Surely DSP power is that much cheaper than it used to be. I know, they have to spread that out to 9 channels so the budget per channel can't be increased. Sigh. As a minimum, companies need to document such things." - I have a doubt about this conclusion: when I send a track with, let´s say, tha is 192kHz 24 bit filed on my smartphone via UPnP to the 503, the receiver displays this resolution. De boubt is: It only displays 192kHz and processes, in fact, at 48kHz or, "de facto", processes 192kHz 24bit as its specification declares?
