All in all, if it actually sounds better than previous incarnations of the Planar series, then I'll defer to Rega to do what needs to be done.
However, manufacturing efficiencies should benefit the consumer in terms of final price, or with higher quality components for the same original manufacturing costs. Rega do seem to be passing along the benefits of lower final cost if indeed the RP6 competes with the P5.
I think what some of the previous posters are concerned about is the appearance that Rega's line is "cheapening" over time, that instead of increasing the quality of components over time for instance, they are instead looking at a price point to drive quality levels. I'm not sure what to think yet, as I have neither heard nor seen these tables in person.
If we can look to American auto manufacturers as an imperfect analogy, the now-classic, substantially-made, labor-intensive muscle cars of the 60s and 70s have given way to lighter, less expensive to manufacture versions of the same models that may not have a concomitant increase in performance, or that may not "feel" the same in use or appearance - maybe never again able to attain that "classic" status. People want their cake and eat it too, given that technology supposedly always improves and costs less over time.
There is an expectation that to one degree or another, everyone should benefit from progress, whether we are talking performance of a car or a table, and we are disappointed when new designs don't meet with our expectations, whether we are talking about performance or appearance.
This analogy is of course imperfect because Regas have always been designed with the "light and rigid is better" philosophy, so we should actually expect their designs to become more minimalist over time if we buy into their approach. However, even my summary of their philosophy is imperfect because the P9 is certainly more substantial than any of their other tables, even including real wood (gasp!).
So if I can paraphrase others' thoughts, why aren't the tables appearing more high-tech than their predecessors? Or conversely, why aren't the new tables looking more and more like the P5 through P9 tables, rather than looking more and more like a P3-24?
Maybe the disappointment is a reflection of the cognitive dissonance of the Rega philosophy rather than the actual performance of their products, i.e. maybe it's still hard for some of us to buy into the light and rigid philosophy, when the resulting product doesn't appear to add up to the sum of the cost of the parts? And if so, is this a problem with Rega, or our perceptions and expectations?
