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

Not sure about the Raven products. I had the Nighthawk MKIII in house and I much prefered my Hegel integrated.
In my opinion, in my system, Raven was one of the most over-hyped products I've heard in 25 years in audio.

devilboy:just yesterday I spent 2 hours between a pair of Harbeth M40.2 speakers driven by a Hegel H590 & cabled up with several thousand $ of Cardas cables,talk about overhyped,You can keep your hegel,I would rather have my Cayin any day!

@freediver  horses for courses.

plus for Cayin

I've heard, and owned several tube amps, receivers, and last year sold my McIntosh SS amp and preamp, to get back to tubes. Needed 16 ohm taps for my speakers, found and bought Cayin Tube Integrated, AT88.

Sound: it never occurs to me to think about anything else.

Features: I wish it had external 'safe' bias adjustment (later models do, but lack 16 ohm taps). Also missing: I prefer having a balance control, and a low volume listening loudness control. I get both from my Chase Remote Line Controller, RLC-1 which I would never be without.
