Amazing little piece of equipment. Giant sound from something so compact. Much better than I anticipated.

One small gripe - once you switch to line in form Bluetooth you need to forget and rejoin the device each time to go back to Bluetooth. No big deal if you’re using one or the other.

Excellent Class D amplifier. I've paired it with my old Sony SS-dx3 speakers which gives great sound, with the 48v power adapter. Shipping took a little longer than expected but it was worth the wait.
