I was using the OPs own post where he related what a reviewer said (and he asked for opinions).
Low listening levels is not a silver bullet.

FWIW I had a pair of 1980? H1s in a 12 x 14 room, but no thanks in my smaller room.
If someone wants to put 20 pairs of speakers in a 10 x 10 room, have at it, just make sure you parallel/series if using one amplifier.
