CH Precision A1.5, P1, L1, X1… A Postscript Review

While I was in the thick of considering the CH Precision A1.5, P1, L1 and X1 late last year, such was the complexity and range of settings and modes and connections, and not least power supply options, that a considered overview was somehow just out of reach. Moreover, those continued and complex evaluations were inevitably constrained by particular circumstances in that more extended trial and error methods to establish quality limits could have added value, for example exchanging multiple cables in all positions, signal, and loudspeaker, and also mains connection methods, whether central or extended line.
