New Fully digital DDX amplifier, the UDP320

Posted by HiFimeDIY 12/03/2019 127 Comment(s)
We have received a lot of enquiries on when our UDP80 fully digital amplifier will be back to stock. So we are quite excited to share that we have a new version coming soon! The UDP320 is an upgraded UDP80, capable of 2X150W with USB and SPDIF inputs. This is not a DAC+amp in one, the digital DDX technology omits the need of a DAC. 
 
How does it work?
This fully digital amplifier is a PWD (pulse width modulation) amplifier that has no A/D conversion, no preamp and no analog signal path before the final output stage. It's kind of like a DAC with high power output capable of driving your speaker directly. But it’s different from other amps that are sometimes called powerDACs, as those are normally regular amplifiers with a DAC built inside.
 
The benefit of this technology is that the output is very clear and natural sounding and with a very compact size. There are fewer parts required which explains the small size, and also makes it possible to sell this great sounding amp at a low price. 
 
The UDP320 has an upgraded output stage compared to the previous version. It now use the same output stage as the T4 amplifier.
 
The amp requires an external power supply, a wide range from 15V to 56V DC is accepted. You’ll get lower distortion and higher output with higher supply voltage, so we recommend 48V to 55V for optimal performance. You can use the SMPS300RS 48V if you’re open to a little bit of DIY to connect everything together. Or the 60V adjustable power supply is also a great low noise power supply supply.
 
The UDP320 will come in a case similar to the udp80 but with individual speaker connection like on the UD80.
 
Estimated to be available beginning of May.

A few time I have bought the T4 amp. Sounds great like 300b SE amp.

please think about an 2.1 solution. i really don't want to make passive crossovers. best solution would be to offer a 2.1 version with 2x STA516. the super clean 1 volume knob design should stay. but simply add (maybe to the back side) crossover and subwoofer gain adjustment knobs or something
