Glad yo hear you're happy with the WiiMs.It's great if it works for you. The Arylics on the main music systems have been replaced by the WiiMs (Minis and Pro, with DACs from SMSL). The Arylics are now (rarely) used in the conservatory, kitchen, guest room, etc. (if so, then also using the WiiM app). They can't be bad in principle, as the technology comes from Linkplay. What annoyed me was the lack of connect functionality and, as a primarily album listener, the "no gapless".
I also had problems with the S50Pro+ after FW updates: they would no longer start/operate. Until we found out together in the Arylic forum that a different power supply unit had to be used temporarily so that a new update could be installed again, etc. In addition, one of the two S50s is accompanied by a switch-on and switch-off “crack”... Arylic now rarely in use. Absolutely happy with all WiiMs.
I'm using a Mini and also a WiiM Amp in another space. Fully happy with both of them, although the Mini gets less playtime these days.
I think I've heard of some issues with the 50+, but the S10+ was a novelty and for 53 EUR, I just couldn't pass up on it, so I've bought it just to try it. Turned out well so far.
Forgot to mention that Mini and the S10+ are both connected to the Atoll DA200 dac with optical cables.
