Bryston thinks it's worthy. Their Pi is stuffed into a nice box with LCD screen and it's only $1295
"Built upon the Raspberry Pi and HifiBerry platform, the new BDP-Pi is faster and more capable than our classic BDP-1 yet fits in a chassis 1/3rd as wide as our full size gear..."

It seems it does not support DSD. And for PCM it can only go up to 192K. So it does not support DXD.
Let me know if my understanding is correct.
Yes of course its worthy, they stuck it in a fancy case for the audiophiles that can't get over that mental thing I posted about....plus of course to enhance profit.
2A @ 12V?
RPIs generally use 1A @ 5V. The uRendu uses 1A @ 7V.
The BDP-Pi also has an LCD display and supports external USB disks and DAC, so they have to take those into account in the power budget not knowing exactly what devices customers might attach to it.
I'm sure the BDP-Pi doesn't draw anywhere near 2A but Bryston may have spec'd it at 2A to be on the safe side should customers decide to use their own power supply. USB disks can be relative power hogs especially during spinup. And -some- DACs derrive ALL of their power from the USB port.
When I measured the uRendu I saw that its current draw was only 200mA (0.2A), maybe a tiny bit more only during bootup. With a USB DAC attached it drew a total of about 240mA from the power supply. That "extra" 40mA was for the USB receiver in the DAC. On another DAC it remained at 200mA as that DAC supplied its own power to the USB receiver. Some other DACs, like those of the Dragonfly variety and similar are powered entirely from USB and could draw even more current.
