OP,
You are describing the sound of Luxman solid state gear. It has that “high end” sound of emphasized treble and bass. But the sound lacks the midrange, natural balance and rhythm / pace. You can’t really equalize it away.
I would consider two possible alternatives Pass INT 60 or Audio Research. These three form a continuum from the sparkly Luxman, to well balanced with good rhythm and pace Pass to detailed / natural presentation and deeply emotional Audio Research I-50.
I recommend you have a listen to these. One will definitely put you in the right category of sound quality.
