This because it is double shielded.
But as said, that requires a total different way of building up the device.

Indeed it is legal in the US for ungrounded 2 circuit line cords as long as primary is double insulated and proper spacing is maintained.
A secondary issue that may not have been mentioned. A properly ground bonded chassis will not only protect against faults in that chassis but in other upstream gear connected to it.
Finally it seems there is some confusion between criticizing the general merchantability of the product or specifically just the safety engineering. I have no doubt that it could sound wonderful.
The dubious safety grounding practice does suggest lack of complete awareness of established procedures for clean signal transfer.
If signals aren't being treated differentially and signal grounds are sloppy it is possible for shield noise current to corrupt audio signals, often remedied by floating a ground. This is only a band-aid that may solve the immediate problem but it is possible with proper circuit techniques to have your safety ground "and" a clean audio path.
Search "pin one problem" for more specific discussion about that.
