If you have a device containing DACs that takes HDMI input, then Sony makes a universal disc transport that reads just about any silver disk (CD, SACD, Blu-ray, 4K Ultra Blu-ray) including multiple high resolution sound formats including Dolby Atmos. It is less than the cost of most interconnects or power cord upgrades!
In Australia, it is available new as the UBP-X700 4K Ultra HD Blu-Ray Player with Dolby Vision | UBP-X700 | Sony Australia. It is on Sony’s US website Sony 4K Ultra HD Blu-ray Player with Dolby Atmos, HDR, and Wi-Fi for Streaming Video | UBP-X700
Note that a new model has just been released with fewer smart TV features.
Despite Sony’s description, technically these are transports, not players, as they have no analogue outputs.
I have two of these which I bought on special at A$250 each. One is at my partner’s place in Sydney, and the other is taped down in my motorhome.
They are amazing value-for-money and I suspect the digital output is indistinguishable from far more expensive transports.
The remote is pretty basic, for example you cannot directly dial track numbers.
I feed one HDMI audio output to a Marantz AV-8802 pre-processor which has eight AKM 2-channel DACs, which natively process DSD. The Marantz tells me exactly what it is being fed
