Personally? If you’re happy, don’t let this bother you, just stay happy with it. I also own an amplifier that doesn’t measure that well, but it still sounds great to me, and that’s what counts in the end. Apparently, the not so good measurements don’t noticeably affect the sound quality, thus I’m certainly not going to sell it for this reason. And it doesn’t sound any less than some of the very best measuring gear out there, that I also own. Would I buy it again, knowing this? No, highly unlikely, good measurements are a prerequisite for me when buying anything new (thanks to the work of Amir, Erin, Gene), btw without resorting to number fetishism. There are other factors that also are important, such as looks, ease of use (e.g. the quality of the remote), component quality, reliability, warranty, service, and, above all (for me), load independence/current reserve. The latter does not always seem to get the attention it deserves and can certainly affect sound quality.I have to say however that I'm very happy with it , fed by ROON using Bluesound Node 2i, Pioneer N70AE and Squeezebox Touch as streamers.
