About the Art Audio PX-25
The Art Audio PX-25 is a stereo power amplifier that utilizes the PX25 directly-heated triode tube, originally designed by GEC in the mid-1920s. This tube is noted for its linear measurement and sound quality, offering a midrange detail similar to the 2A3 but with more frequency extension and power. The amplifier is available in different versions, including the PX25 MKii, which features a chrome chassis and weighs about 60 pounds. It delivers a power output of 5 watts per channel and is designed with a passive line stage, remote volume control, and three single-ended inputs. The PX25 MKii is handcrafted in the UK and offers a frequency response of 10 Hz to 20 kHz +/- 0.5 dB, with a signal-to-noise ratio greater than 85 dB and total harmonic distortion less than 1%.
