It's good, but... No, it's bad.
Product came from the USA so it took a little time but after receiving and installing it initially seemed to work OK. However, the trigger function is a problem. Connecting to an Arcam AVR20 Integrated Amp to sync power on/off. The trigger functions fails to operate, indeed there is a "buzzing/fizzing" sound coming from the SMP500 and sounds like a short-circuit... I immediately pulled the power cord fearing damaged to either my AVR20 or the SMP500. I checked the polarity, voltage and current of the trigger cable and AVR20 output and it is within spec ( AVR20 DC +12v 70mA, 3.5mm jack, tip +). and correctly wired. In the "On" mode, it works as expected but the "Music" mode should turn off when a signal is not present and on when a signal is detected, but it's unreliable, sometimes it does, others it doesn't. I attempted to find a support link to the manufacturer (OSD) but they only offer dealer support. On the Amazon order page there is no option to "ask a question", so I contacted customer service and the only option was to return the product, no help there. I suspect that it has a fault, or the labeling is incorrect (e.g. the + and - symbols are incorrect or specifications are wrong), can you please confirm the the product labeling is correct (+ and - and trigger in/out and switch setting 12v/On/Music). Setting the switch to "12v" and "External Trigger On" in the software setting is what I understand is correct but that can't be confirmed it seems. I have decided to keep the product but am concerned that it will be a problem in the future, a risk. The reason for only two stars is that there is no UK support, to even ask a question of. So after the 30 days Amazon option of return any warranty is useless it seems. Update. Now there's a pulsing noise emitting from the driver, even when the phono isn't connected. This noise is sufficiently load that I can hear it 15 feet away in the primary listening position during the quiet gaps in films/music. For a £600+ device this is unacceptable. Now being returned and reduced to one star, zero if there was an option.

Great sounding amp
Coupled with the OSD 12” sub and it’s a fantastic sounding amp.

Awesome amp
I am using this to drive 2 Forza10 subs, the sound is amazing using this amp and the control settings are great, highly recommend. Can never have too much power.

Nice class-D amp
I just wished it was WiFi controls instead of a ir-remote
