Can't get Acoustic Zen Adagios to sound smooth

I have owned a pair of Acoustic Zen Adagios speakers for over 4 years. They can sound very good, BUT also have a HARD AND UNSMOOTH sound when playing certain CD's. I have changed electronics from separates to an integrated amp, and recently purchased a Ayre CX-7e to replace a Rega Apollo. The Ayre easily highlights the limitations of the Rega player and outperforms it.

Nevertheless, the hard and unsmooth sound seems to prevail. It can also sound like an acoustic overtone, and (I think )the music looses its bloom or musicality. The current living space is well damped with maps,and rug hangings on the walls. I also have two 6 ft tall bookcases that contain only 70% less books than my previous apartment These shelves are in the corner, perpendicular to the speaker on each side of the room.

I encountered this problem before in a different and smaller living space.

I also recently changed speakers cables from a 4 year old pair of Audio Art SC-5 to a brand new pair of Grover Huffman which seemed to be slowly breaking in and are more detailed than the AA cable. I also replaced the standard wimpy power cord of the Ayre player with Panagea's new 14SE MKII power cord designed for just components, not amps. The Panagea PC is excellent, and has dropped the noise floor allowing for more detail to emerge. I drive the Adagios with the Rogue Sphinx hybrid integrated amp (100RMS)whose PC was replaced by an Acoustic Zen Tsumani Plus power cord.

I am beginning to wonder if there is another speaker that might provide a smoother top end performance and still have the taut bass, and detailed mids of the Adagios. Will appreciate all and any advice, even new speaker recommendations. Thank you
