I’m not familiar with Hifi Rose but have read good feedback from owners, and the RS151 looks to offer everything you’re looking for if the sound quality is there (didn’t see any what I’d consider reputable reviews after a quick search). I’d look at the functionality of their app and whatever customer support they offer as those things are important for longer-term satisfaction. I’ll also mention the new Eversolo A10 with the caveat that I’m not confident in their customer support that could be very important. That said, from a features, sound, and value proposition it seems to be all there, and here’s a review from a reputable reviewer that may be helpful…
Frankly, if sound quality is paramount I’d forgo the combo unit and video screens and go with separates, but that’s me. Hope this helps, and best of luck.
