I had a Rega RP-6 and now have a WT Amadeus Mk.ll. While I agree with a lot of what the OP said how the two compared in operation, the WT is a much better sounding table. I still think the P-6 is a cool table for the money. You can't go wrong in purchasing one. IMO.
New Rega Planar 6
Just got a new Rega Planar 6 and Dynavector 20x cartridge—replacing an aged 25+ years)Well Tempered Turntable with Dynavector 10x. It’s only been a few hours but I’m impressed so far—and it’s nice not to have all that fluid sloshing around and the multiple adjustments (in my case mis adjustments) of the WTT. The Rega seems just right in terms of features, adjustability and-of course-sound. Back to listening. More after some time.
