sound of these speakers forever. Personally, I would be satisfied with either, just on the recommendation of some of our members. As for my 19's, I have disconnected the woofers from the crossover and connected a Dynaco ST400 amp directly to my 416 woofers, connected a Dynaco ST70 to the horns through the crossovers to utilize the EQ and both amps are run through a Chinese made 6SN7 tube based preamp with only a volume control. Works for me. Eventually, when my very busy audio guru friend(40 years working with every electronic known to man) gets to it, I will try two EV electronic crossovers with EQ. The setup was recommended by him.
