Some DVM do have a peak and hold facility, and you enage the peak and

I got such a DMM from Maplin quite a while ago (they still do it - WG022
at about 60UKP I think) but I had forgotten that it had max/min hold on
it! I just tried the above (but only for one track) and got a max reading
of just over 1.9v with the music "fairly loud". That's a smidgen above
0.45W per channel if you believe in 8R speakers. That seems to be about
right to me. I can't run "concert hall" volume with small kids next door.
