Whatever you want to call, having volume control at the input, having ability to choose one of the three input is an integrated amp.

Yet another Class D but this time using the onboard PS. It comprises a diode bridge with ultra fast soft recovery diodes and 10,000uf Nichicon cap. All quality parts. I added a 500VA tranni and a 0.1uf poly snubber t the Nichicon. Amp sounds very good. I've called the amp "najah". These boards are packed with quality parts; Jantzen and wima are some and comes with speaker crow bar protection.

Bass sounds heavier than my T3 expensive monoblocks. So easy and cheap to make a 180Wpc amp which is true hifi due to extremely low distortion figures. I know ultra low distortion doesn't always mean it sounds good but it does mean it is true high fidelity.

Mark, I like the boxes you’re using for these amps with built in ventilation. are these available commercially or are these specially made?
