I asked Brian Cheney this question about a year ago at a gathering - the man makes some great speakers for
decades now and is well versed in music. His answer was we're at about
80% of 'real'.
That seemed about right...we're a lot further along than 1-5% I'd say...I don't think any of us would keep plugging away at it if we weren't closer than that to 'real'

I think if you have a small-ish room, your goal of achieving
realism will be better served by analog (vinyl or reel-to-reel) as the relative lack of dynamic range, stereo separation and other matters won't be noticed
as much (probably why folks in UK, Europe, Japan have kept the analog flame alive is, in general, are their smaller living spaces than in the US and Canada). A record might have information down to 35 hertz on it, a digital technology 20 Hertz, so powerful bass waves that can muck up the playback space is far less evident, too.
If you have a large room, full-range speakers (or speakers and subs)...the room
has got to be treated well to get the most from (demanding) orchestral music and today's digital technologies and have any sense of realism (much as DGO/Denny is refers to)
