From your point of view, yes, good for Denon but don’t forget that Pioneer still has what Denon wants (needs) which is that earned and trusted reputation Pioneer has.
It was smart of Pioneer to copy the SC units because (if we’re being honest here) there are still a ton of people who were not willing to part ways from their trusted Pioneer gear and even if they were contemplating, now with the release of the 3000’s, I would say that the chance Denon had to take more of Pioneer’s customers has diminished. Sure, there will always be people who will switch due to price, or common sense (lol) but at the end of the day, Pioneer is still wearing the crown in the industry and Denon still needs to work hard to take it away from them (please don’t confuse the last statement for me suggesting they deserve the crown, that’s not what I said).
I think that Denon needs to remember that what helped them gain a bit of success with the Prime decks was their price point and if the Denon gear is too close in price to the Pioneer gear, it will be an uphill battle for them.
Just my thoughts…
