Digital Amplifier Company aka Cherry Amplifier ...

Several things that would keep me away.
1. Not mentioned physical location of the factory or 'ships from'
2. Unknown company if things go down south 
3. Prices are up North nevertheless.

It seems that amps are assembled and tested in China where you can get same stuff 20 times cheaper from DH-gate or Alibaba. 

Spoken with such great authority that you would swear it is true, other than it is completely wrong. 

The amps are built in and ship from Pennsylvania. He doesn't just slap modules into a case and call it a day. So, no, you cannot buy the same thing 20 times cheaper from DH gate or Alibaba. 

I use the two cherry king on the tweeter section of my fully active Legacy Calibre XDS speakers. It works great for that. I have not used it for anything other than that.

They have a pretty big following on AudioCircle, try there for more info.
