Not automatically, no. We've Group Tested the EB1s against speakers much closer to them in price terms than the 685s, and it's really a question of how much less than £500 you're looking to spend. We're concerned/obsessed with value for money, and the 685s continue to have a most attractive performance/price ratio.
EB Acoustics offers a 30-day, money-back guarantee, of course, so auditioning in your own home with your own electronics shouldn't be too daunting.
