"I started looking for something new simply because digital technology seems to improve at a rapid clip. The best digital I've heard (Wavelength, Ayre, Boulder, and ARC) has been phenomenal. All of those "bests" sounded much more resolving than my Rotel (admittedly in different systems) but very relaxed and easy to listen to at the same time.
The Rotel sounds very, very good, but I wondered if a newer player might give me a taste of what I'm missing."
You can definately improve the sound of your system with a better player. The brands you list above are all excellent. You may want to consider a Wadia. If you like Ayre, you probably like that as well. Wadia. Cary is another brand you may like. Their digital products are very underrated. Given that you already have the 1072 and you like it, I would take my time in making another selection.
