HiFiTOY
That's the most challenging model with an impressive list of breakthrough features. ..Stop, I've promised: no any marketing BS over here ))
Ok, I've noticed last years getting popular the small footprint class D amps with external power supply and 1.5m thin cable between. I was surprised at how that absurd idea comes true because technically it is obviously stupid, many of us remember audio magazines/ DIY forums discussions about the role of accurate and solid rail power supply in the audio amplification. So, today $4 power brick for LED purpose with 1.5m of noodles-cable is ok to power HiFi? No way, my little friends, hands off from audio! that's why I decided to design a compromise-less power supply and Fully Digital Amplifier(FDA or Power DAC) in the same tiny housing with a lot of inputs formates, and DSP controllable by iOS/Android app for extensive Bi/Tri-Amping crossover filtering/phase alignment. 125Wx2ch 154x108x36mm In fact, you can hold it on your palm. To turn it on need just touch the bevel on the front panel, to change volume slide your finger left or right. The preliminary release date is undefined yet.
