CORE series ditigal amplifier is designed to meet the specialized needs of sound contractors.Three models,the core650, core850 and core1050.CORE amplifier are based on an improved version of PWM technology, equipped with very high efficient and reliable switching power supply with power factor correction(PFC)。
With the Muservopower(TM)and ToneAdjust(TM) technology。CORE amplifier take your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs.it also cuts waste heat,boosts reliability and gets rid of unwanted noise and hum.

Chinese made......never heard of 'em. I'd stick with good brand names if you can. Crown, QSC, etc.

Pretty much all amps are made in China. That one appears to be a knock-off, which almost always are of poor quality. PulseMan has reported very good success with "Sync" brand amps. but, a +1 to Bruce Weldy. Stick to well-known, service proven reliability.

They don't appear to be sold in the US, so it's not likely anyone here will have experience with them.

I don't know about their switchmode amps, but their conventional super heavyweights are great value for money.
http://www.deton.com/html/amp_Aone.htm will do 4 ohm bridge all day long but need a good limiter to keep them in line.

We tried two OTop 12 Jarrays with the deton core 1050 and it was stupidly loud with a lot of juice left on the amp. We intend to run four of the amps for the eight tops bi-amped.
