1V = 105dB peaks
So depending on the DR rating and type of music this means you can reach 90-95 dB SPL.
As most energy will be in the lows and our ears aren't as sensitive there you may be looking at 80-90 Phon so means playing at a ‘comfortably loud’ level which is easy to listen to for 1 or 2 songs before getting the urge to turn it down to more comfortable levels. (at least for me)
For classical recordings average levels will be lower.

No problem for playing pop music at reasonably sound levels.

Also one has to realize that occasionally slightly clipped peaks aren't very audible.
