Before you pull the trigger, check out service, support and warranty for the DPS - their motor controller is proprietary and complex. I chose the Galibier, not just because it sounds better, but because the motor controller is a simple circuit using very common components. The only part with a failure risk is a regulator costing $2 that will be available indefinitely. The rest of the table is built like a tank and will last for ever.
A Tri-planar is all the tonearm that anyone would ever need ($4k) so with $4500 left to spend you could have yourself a new Galibier Gavia with Serac platter. I know the Schroeder new retails at $5500, but that just makes the Tri-planar even better value in my view.
The great thing about the Galibier design is the mylar belt which delivers rock solid speed stability (compared to the DPS's rubber). The DPS has an AC motor (vs DC) so will be prone to cogging and it needs that stretchy belt to counter this - the result is you don't get the dynamics and absolute pitch stability of the Galibier. Also compare the bearings between the two tables.
And you would have the pleasure of owning a new piece that was built especially for you.
