???Anyone Here UpGrade From Yaqin/Cayin/etc... To Another Tube Amp Considered Hi End???

just goes to show you how we get accustomed to what we have owned.  
owning a raven audio nighthawk and blackhawk i found the sound to be neutral, highly refined and colorful with outstanding transparency.  sounded spectacular with kef ls50 speakers. 
first and subsequent times hearing hegel amplifiers i thought they sounded obnoxious and closed.  bass was pounding and out of balance, midrange was smooth but lacked transpareny.  
i could never live with that kind of sound.
