It advances the celebrated P1 with a gain architecture informed by the flagship P10, combining two current-sensing moving-coil inputs with a greatly improved voltage-sensing MM\/MC input. Three active gain stages with ultra-precise passive equalization between each, software-assisted setup wizards, optional historical EQ curves and dedicated mono modes give it exceptional flexibility for both modern pressings and historic records.\u003c\/p\u003e\n\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\n\u003cp\u003eThe P1.5 lets a great cartridge show everything it is capable of. Low-output moving-coil cartridges on the current-sensing inputs sound remarkably quiet, fast and settled, with fine detail and natural decay emerging from a deep black background, while the voltage input offers more than 400 loading values for MM cartridges, step-up transformers and high-output MC designs. What sets it apart in daily use is how approachable that precision becomes - the Gain Wizard and Loading Wizard take the guesswork out of setup, and the correct mono and historical EQ settings let older pressings open up with real energy and scale. For serious collectors with a varied record library, it is one of the most complete phono stages we know.\u003c\/p\u003e\n\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent- and Voltage-Sensing Inputs:\u003c\/strong\u003e Two virtual-ground current-sensing inputs suit low-impedance MC cartridges without resistive loading, while an MM\/MC voltage input offers selectable loading from 20 Ω to 70 kΩ across more than 400 values.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eP10-Derived Gain Architecture:\u003c\/strong\u003e Three discrete Class-A gain stages with passive equalization between each improve EQ accuracy to ±0.1 dB, lower noise and add gain headroom, adjustable in precise 3 dB steps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetup Wizards, Historical EQ \u0026amp;

It also brings a greatly improved voltage-sensing input with more than 400 loading values, finer 3 dB gain steps, setup wizards, improved EQ accuracy and dedicated mono modes for two-coil and single-coil mono cartridges.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich input should I use for my cartridge?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLow-internal-impedance moving-coil cartridges are best suited to the two current-sensing inputs, which need no resistive loading. Moving-magnet cartridges, high-output moving-coil cartridges and MC cartridges used with a step-up transformer connect to the voltage-sensing input.
