Everything is possible given enough resources … whether it’s practical is another matter.
You wouldn’t really run anything directly off an inverter and a solar array - you’d always want a battery buffer there so that your Dark side of the Moon wasn’t laid waste by the dark side of a cloud and it would be down to the inverter to be able to provide enough voltage and current to maintain a stable supply.
Of course whether it would SOUND any good doing so would be a different discussion altogether - I’m sure someone will be enterprising and do audiophile solar panels!
I am in the midst of a house refurbishment. We are connected to a new three phase supply which is primarily in place to power two 27kWh air source heat pumps for heating. One of the three 20A phases is going to be run to a separate consumer unit and then to the listening room using high quality mains cable and terminating in audio grade power sockets. We have 24 solar panels on the roof which will run into the secondary power circuits via an inverter and batteries and (when solar power is available) supply power to the ring and lighting circuits, including the 20A feed to the listening room. When solar power is not available, the power will come from the single phase of the three phase supply. Not quite a pure solar powered system but probably as close as it is possible to get with the unpredictable weather in the UK! I think this makes it almost identical to the system described in Audiophile Style.
