I built this one with 2 customized TPA3116 modules, a beefy power supply, Alps Blue Velvet volume control, all housed in a quality aluminum chassis.
I use identical one with my Zu Omens and this amplifier is the only digital amp out of many that can handle 16 Ohm load without HF filtering issues. Sound quality is comparable to my LDK300B minus the heat.
