This is premium version of my old DAC AH-D6 (2 Layers PCB). The new DAC is made on an improved 4-layer printed circuit board. AH-D6.1 has improved the power supply regulator and analog filter circuitry. DAC has ultra-low harmonic distortion.AK4493 - 32-bit Stereo Premium D/A Converter DR, S/N: 123dB, THD+N: -113dBPCM up to 384KHz/32BitDSD/DOP 64,128 and 256 I2S input (master and slave mode), 2x5 Pin - 2.54mm connector2 scales (44.1x/48x) MCLCK oscillators on board (NDK femto clocks)11 Super Low-Noise voltage Linear Power regulatorsAK4493 VREF Ultra–low noise Linear PowerHardware Relay Mute at the outputsMicroprocessor based controlSharp/slow roll-off filter switch (jumper configuration).THD < 0.0001%, THD+N < 0.0002%Board size is 69x100mm, 4 layer PCBMore Details: http://audiohobby.ru/articles/vysokokachestvennyi-cap-ah-d6-1-na-ak4493-ak4490-premialnaja-versija-ah-d6.htmlRecommended Interface Board (USB-I2S):https://www.pcbway.com/project/shareproject/Combo384__Amanero____I2S_isolator_v1_5.html

The maximum that can be achieved from the inverted inclusion of TDA7293. Perhaps only composite inclusion could be better. Not a simple project, it is not recommended for beginners.

This is the best-sounding class-D digital amplifier on a chip I've ever heard. The sound is close to a good class-A B amp

this amplifier is a clone of the famous even for someone legendary, Cyrus 3i These are "parallel" with a slew rate of 140 V/s. Very driving and detailed sound.

PAM8610 is a 2*10W dual-channel class D power amplifier with high efficiency and low heat.The power input is DC5521 interface, 12V input voltage. (At least 12V2A)Audio input is a 327 audio interface and HX2.54-3p interfaceAdjust the volume through a 100K single potentiometer. Because the volume is achieved by voltage regulation. Therefore, the chip will not have any rustling sound of other input terminals to adjust the volume.There is a mute interface at the end of the board. An open circuit is a working state.
