Yeah, there is a difference, but one that you may or not notice. For home use I’m happy to use my Xvive, even though i hear the difference. Its more the tail end of the notes rather just overal quality. My comment was more aimed at gig use.
I also see a much better connection between the Boss compared to the Xvive at home. I get a lot more drop outs with the Xvive, even though I’m less than 3ft from the receiver. With the Boss it seems to be rock solid most of the time.
I like the Xvive as it has a proper on/off switch, meaning i can leave it plugged in to my (passive) bass and Stomp. With the boss I have dot unplug after use other wise the battery drains.
Ive never used the really cheap systems though.
