Let me thank everyone who have responded so far, and provide more info about the room and speakers. The speakers are Acoustic Zen Adagios. The room is a dog: 14X12 with about 8 ft ceilings with one wall of windows and glass sliding door. Opposite the window wall is counter that partially opens into a small kitchen. The wall the speakers are located is not continuous but juts out to accomodate air-conditioning vents. I sit across approx 6ft from both tweeters. This wall is continuous, and will be location when I find the energy to move the 80lbs speakers. There is a flat screen TV between the speakers that is covered over with a bed comforter during listening......I play alot of classic rock, especially YES, Allman Brothers, Grateful Dead. I play it loud, but am not a headbanger and believe accurate volume control is worth its weight in gold to help pressurize a room. I have concluded that the recess in the wall of the current speaker location is creating an augmentation to the sound that creates a mildly bloated sound and somewhat lively highs.It also lessens focus and depth of soundstage.... Also, Adagios seem to shelve back the lower mids, so the sound is not forward or in fromt of the speakers.
Related to "Unsound"'s question: I am looking to achieve a more musical presentation that is described generally by Mr. Timlub: a liquid midrange that is still detailed, taut, tuneful bass and smoother highs. My Creek 5350 Classic has many virtues, but it sounds mechanical, and has somewhat spity highs, and lacks some bass control. One final point I need to change the speaker cable which is Analysis PLus Oval 12---good cable, but not up to capabilites of the Adagios. I am favoring Acoustic Zen Hologram II. I am also changing the stock PC of the Rega Apollo with AZ's Tsumani Plus which should provide some improvement to the sound.
