Another impressed owner here, feeding them with the Schiit Vidar and Freya. The imaging is really good! Warmth with detailed highs, a neat trick there. The budget speaker market has really improved in the last several years.
I've got a pair of the old Pioneer BS-22 that i'd been somewhat unimpressed with and left them in storage. I recently took them apart and soldered all the interior connections, which has changed my mind on them. I might just try that with these Sonys.
