1/19/2024 0 Comments Precision power amp reviews![]() ![]() Here we have many factors which could blur and obstruct the qualities of focus, dynamics, and transparency in the reproduced soundstage. For example, to reach peak performance from a high-end phono preamplifier / equaliser such as the CH P1, which processes microvolt signals from the pickup cartridge, it is all in the installation detail. With equipment of this quality, reaching something close to optimum performance requires thought and meticulous attention to detail. They would likely have assisted with suggestions and alternative trials and combinations, and I would have benefited from their opinions and hands-on support.Īs conceived, the project planner, working remotely with Definitive Audio, made a particularly good stab at the overall proposition, seeking to deliver as much infrastructure as possible to embark on this massive system review. It seems clear to me that if the Covid-19 lockdown had been absent, I would have welcomed sharing the auditioning with colleagues. Looking back at the many pages of notes made during my extended listening tests, some extemporising now seems possible – and may add value to the review analysis. Then there is the matter of optimising the choices and subsequent alignment of anti-vibration frames and optional intermediary supports. 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. Volume 14 Number 4 Oct - Dec 2020) 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.
