To get the most out of the Wadia you need an exceptional external DAC. Using the Wadia just as a dock IS indeed overkill and you'll be as happy with a Cambridge or something like that.
I've got the Audioengine speakers and the Wadia, but use the Wadia in my main system, feeding it through a SOTA DAC with exceptional results. If you've got a great DAC laying around, then it'll be very nice. The AE speakers are up to the task, but if you have to buy a high quality DAC for the pontoon boat, then that's probably overkill.
