Good for the price. Pros: high power (enough for most of mid-sized speakers, I bought it for shelves but also tried to pair with Mirage OMD15 and it has plenty of power to pump them); Good bluetooth quality(aptX, good antenna so on); nice build and finish; good isolation (no cracks, hiss etc). Cons: too much bass by default - good for entry-level speakers but if your system could play real bass, you'll want to flatten the equalizer (and this amp doesn't have any, so software or preamp only) ; no Bluetooth security. You may not like: Bluetooth always takes over line-in.
