What makes mine special? Starts with the shortest signal path. Dac runs direct to the mono amps via balanced XLR connections. Amps are located at base of the open baffle speakers and connected with 1’ of DIY speaker cable. Servo controlled open baffle DIY subs. Room is diffused live end / absorbed dead end. Ekornes stressless lounger. Fatigue free - always.
Future improvements would be ceiling treatments...a larger room, possibly.
(I run DAC Cherry amps and dacs feeding Spatial Audio speakers. Subs are GR Research)
