Know before you buy
HV stands for High Voltage. By operating the internal circuits at significantly higher voltages than standard designs, the P 3100 HV achieves superior linearity and lower signal modulation, which results in a more dynamic and transparent sound.
The dual mono design physically and electrically separates the left and right channels, including independent power supplies. This eliminates crosstalk between channels, providing a wider, more precise soundstage and improved imaging.
By using pure DC coupling, T+A removes capacitors from the signal path, which can often color or restrict the audio signal. This approach ensures the most direct, unadulterated path for your music, preserving phase accuracy and detail.
No, the P 3100 HV is built entirely with discrete components. By avoiding integrated op-amps and utilizing hand-selected J-FET transistors, the design maintains higher signal integrity and avoids the limitations inherent in mass-produced chips.
Yes, the unit is highly versatile, featuring 4 XLR inputs for balanced connections and 6 RCA inputs for unbalanced sources. One of the RCA inputs can also be configured for an optional phono stage.
Yes, the P 3100 HV is exceptionally heavy due to its robust chassis and large toroidal transformer. You should ensure your rack or shelf is rated to support at least 62 pounds and provides enough depth to accommodate the 18-inch deep chassis.
