Bad because:
- there'll be Eden-style missing audio at the start of tracks
- there'll be more receiver switching and/or drop-outs

I guess this must depend a lot on individual set up as I've never noticed either of these on main htpc connected via hdmi to an avr or my bedroom htpc connected via optical spidf to an avr or perhaps it's there but just too short for me to notice

It will depend on several factors for sure:
1) your receiver and it's switching time and reaction if no incoming data (the latter being an issue on very few receivers)
2) your processor speed
3) whether you switch much between different file types, e.g. mp3 to FLAC and back

There's some minor issues in PAPlayer that need addressing when tracks switch as well that are a bit of a priority on the list.

The good thing is now you have options
