Okay, so I finally pulled the trigger on the WiiM Amp after weeks of reading reviews and watching YouTube comparisons. Here's my honest take after using it for a month.
First off - this little box PUMPS. I'm running some old Polk bookshelf speakers in my home office, and the difference is night and day compared to my previous setup. The 60W per channel is no joke - fills my medium-sized room with crisp, detailed sound even at moderate volumes.
The app is where this thing really shines though. Being able to control everything from Spotify Connect while sitting at my desk? Chef's kiss. The multiroom feature works flawlessly with my existing Google Home devices too.
Pro tip: The HDMI ARC connection to my TV was stupid easy to set up. Now I get proper stereo sound for movies instead of that tinny TV audio. Added a cheap subwoofer and boom - instant budget home theater.
Only gripe? No AirPlay support (I'm an iPhone user). But honestly, Spotify Connect works so well I barely miss it. For $300? Absolute steal if you're looking to upgrade your audio without breaking the bank.
