DR = Dynamic Range, expressed on a Scale of, say 1-20; with 1 being the worst or least dynamic/most dynamically compressed and 20 would be so dynamic you'd probably blow your amps and your mind in the process!For the novice, what does this mean: "DR's are 11's, 12, 13's, 14, 15."
for Rock/Pop material around an 8-10 is desirable and 11-12 great, 13-15 is exceptional, although the amp will need a bit of cranking
