My new living room geometry doesn't really support my current setup of Cambridge Audio azur 540r+Monitor Audio RX6 fronts + Usher S-520 II rears. I was thinking of selling the 6.1 amp and the rears and buying a DAC (CA Dacmagic 100 or plus) and an amp in the range of 400£ Any good suggestion for a linear power amplifier with two channels? Or comments on my strategy generally? My main source is digital output optically from my TV to which I input from aerial or tablet. Maybe buying an LP player later.
