In fact, the aR1p’s make a fundamental difference. They improve the overall transparency and clarity of the sound. They provide a fundamental increase in definition. Yet, they do this without adding a trace of brightness or any sense of an etched coloration. They in no way inhibit dynamics or micro-dynamics; they do nothing to obscure the natural rhythm and pace of the performances. What the aR1p’s do is simple; they just made everything sound more like music and less like recordings.
