Its weird that everybody who has an Evolution Acoustics speaker has a Darzteel amp.
the Evolution Acoustics use an integral digital amp to power the 15" woofers; which allow for a 93db, 6 ohm speaker which only needs a main amp to power above 100hz. one then has the opportunity to choose a mid or low powered amp with maximum refinement and naturalness. the dart then becomes the ideal solid state choice to use. when you hear these two products together it is easy to understand why they are combined.
what other mid-powered solid state amp would one choose that is better than the dart? some are likely a bit different; but better? there would probably be a few different tubed mid-powered choices which one could choose.
And everybody who has both has a Playback designs cd player.
obviously; the source for the above products manufacturers the Playback Designs....and therefore these customers are naturally among the first to be offered the Playback Designs.
i suppose synergy is above everything.
actually; there are a good percentage of early Playback Designs owners who own neither the Evolutions nor the darts. these other owners are experiencing the same performance leap that the Evolution-dart people are.
i think that amps and speakers must be synergistic to work.
the highest quality sources should synergize with any/every natural, high resolution system. sources should be neutral and should not require specific speakers or amps to work right.
