I run a 99 db/w system with a compression horn midrange with a 5 watt pushpull amp or a 6.5 watt parallel single ended 2a3 triode amp. Both are quite adequate for the job. The only time I feel the need for more power is when it is playing acapella choral music; for some reason, this type of music begins to sound a little more muddled at surprisingly lower volume than other kinds of music.
The best thing about horn systems and really good low powered amps is that the music is VERY satisfying at LOWER volume than other setups. I find that the better my system gets, I listen at lower and lower volume.
