Hi Erik! Mundorf MKP capacitors replacing the rectangular pink caps on the Parts Express YuanJing 2 x 68w LM3886 and NE5532 board makes a big difference. Better yet, run you audio into the second cap and skip the NE5532 stage completely.
DIY forever!
After reading (AudioXpress July 2020) about the new amp module (1ET400A) from Purifi Audio in Denmark (by the same fellows that built the nCore amps), I bought their EVAL1 package made for evaluation by potential purchasers (like NAD and others) consisting of two Class D amp modules (400 wpc @ 4 ohms, very low noise & distortion, unmeasurably low output impedance) and a front end with protection circuitry, extra gain, and input & output jacks. You have to build a suitable power supply to use it. Got it right on the second try. The amp is getting sensational reviews and I must say it's the best I've heard. Great specs and performance! You can own it for about $1000 with the power supply (you must build). Extremely good.
Linkwitz LX521-4 speakers, DAC upgrades (SMSL cute little red rectangle), lots of music, speaker builds & mods, ukulele groups, performing, and being grateful for a wonderful wife and church involvement fill the rest of my life. Keep smiling!
