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


Say something from Ayon,BAT,AR,Raven,Rogue,Unison etc....
Did you gain anything from the upgrade?Lower noise floor increasing low level resolution?Tighter more defined imaging & staging?Anything?

Thanks for your detailed response. I apologize for misreading which amp you had. My bad. Either way, it sounds like your experience with Raven Audio left a bad taste in your mouth and that is unfortunate. My experience with them has been completely different so am hoping yours was an anomaly - no one wants that kind of bad press, with regard to their product or their customer service.  
My experience with Raven Audio was completely positive. I bought my Blackhawk used and when I contacted Raven owner Dave Thomson about a minor problem with the remote control he followed up with multiple messages and phone calls helping resolve the problem, even though he was aware I'd bought the amp used. He had me open the amp and send pictures of connections he thought might be the problem and followed up every time to find out if the problem had been solved. It was the best support I've received in 50 years of owning audio gear.
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.
