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

@freediver  For years I've always wanted to try Icon Audio. Please let us know your impressions.

I owned a Jolida 502p amp for years and it worked beautifully, but when a Dennis Had Inspire "Firebottle" SEP (pentode) showed up as a barely used item on Ebay I jumped on it. I realized (even before switching to  very efficient speakers) there really is something to the smaller single ended tube amp, and these Had amps, although somewhat rare due to Had's relatively tiny product output, are outstanding designs utterly handmade.

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.  

@dgcurtis36  understood and no worries.

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.
