lanx0003 - Your question is spot-on. Truth is I very much like the Jade 3's paired with the CXA81. Only limitation is a certain muddiness or lack of crispness in the 500hz region, especially with piano music. I'm guessing that is a room acoustics issue. I've maxed out the WAF with a pair of tube traps, panels, heavy curtains, etc. I purchased a miniDSP SHD streamer with Dirac Live to address remaining room issues. The SHD is up and running but I haven't implemented Dirac Live yet.
Yesterday I auditioned the P3's at Decibel Audio in Chicago. The magical midrange was quite evident. Combine that with excellent imaging and soundstage gives one great sound. Better than the Jade 3's and worth the extra $? I don't know yet.
Same sort of issue with the dac. Moving from a Bluesound Node2i to the dac in the CXA81 was a major improvement, and for my use I am very satisfied with the SQ. Why consider something else? Well, it's the nagging feeling that even better SQ is within reach. For example, I've read good reviews and agon comments on Chord, Denafrips and Schiit dacs, just to name a few within my price range. Would I notice an improvement in my room with my music, etc.? Would I consider the extra $ worthwhile? I don't know, but over time I intend to find out. In the meantime I will continue to enjoy the Jade 3's and the CXA81 because, as you imply, there is really nothing wrong with them. Regards.
