This was exactly what I was looking for in a desktop speaker amp. It has all the features I wanted and a few nice-to-haves that I wouldn't have thought to ask for. When looking for an upgrade over my previous amp, the Dayton Audio DTA3116HP, I wanted something that kept the banana connectors and headphone output, while adding a built-in DAC and outputs for a powered sub-woofer, all without being enormous or outrageously expensive. The AD18 ticks all of these boxes and then keeps on going, including Bluetooth 4.2 w/NFC pairing and a full-featured remote. It does have some quirks, like the "1" volume level that produces no sound despite also having a level 0 and the generic remote (w/SMSL branding) that includes function-less buttons. For me, these are minor faults for something that under-promises and over-delivers in every other area especially at this price point.
