Fjn04: as far as the differences bwt the two, I spoke to two different salesmen at two different companies*. One said the main difference was a shiny chrome faceplate and a few hundred bucks and absolutely nothing else. The other said it was a completely different model and blew the standard out of the water?
I grabbed a dyna 10x5; seemed like a moderate choice with two kids running around. Not a lot of experience to compare with other pairings. To my the ear and 10x5 seem to be great with Jazz (Saxophone Colossus) and acoustic (Young Live at Massey Hall), and good with rock (Fever Ray).
