![]() Connecting high-level inputs from the amplifier outputs to a subwoofer are now much more viable without the half power-supply-referenced outputs you found in prior models. "Also worth noting is the fact that the amplifier outputs now remain at a ground potential which alleviates many of the implementation hurdles prior ASP series amplifiers posed. I would say that the majority of improvements come from the latest refinements in the ICEpower HCOM modulator which offers extended bandwidth, lower distortion and improved dynamic range. "Working with ICEpower over the last 13 years, we have learnt many things. Comparing these modules to the prior versions, you will find a smoother warmer sound. Whilst preventing any chance of a noisy power supply should the AC mains suffer under-voltage conditions. FROM THE WYRED 4 SOUND website Utilizing the latest generation of ICEpower® technology with a completely redesigned input stage, the mAMP is a highly efficient amplifier that delivers superior audio quality. Significance of this is that it provides a maximally clean DC supply level Raw DC reference is used to create the desired output level andįiltered three more times before providing power to any audio circuit segment. The latter tends to vary from household to household as it'sīased on the actual AC line level which the regulators are powered from. These new regulators areĬapable of setting the optimum output level based on the pre-filtered Praised STP-SE preamp albeit there without yet the tracking section. Triple ripple-reduction tracking regulators which were originally found in our highly To prevent over/under power-supply regulation we employ our new Separates, we could also move away from fixed regulators to something moreĮxotic. "Since we had more real estate in our new The upshot of it all is a new input stage capable of driving upwards of 12Vīalanced with <0.0007% THD+N and a noise level downwards of 0.000007V without a filter! It's that residual noise which is lowered by reducing output gain. The beauty is that the overall noise floor prior to the level reduction is derivative of what sneaks past the common-mode rejection. "Some may think, 'hmm, you add 6dB, you remove it again, big deal'. ![]() This extra gain is not preferable per se other than the fact that we could now reduce the output level by the same amount to amplify less noise. Noise and better common-mode rejection. Another key benefit comes from the extra 6dB of gain as a result of the cross-coupled topology. "This versatile new front end creates higher dynamic range from lower
