Audion Silver Night PX25 Anniversary Stereo Hard Wired Amplifier

Contact Us for Pricing and Availability


Silver Night Anniversary amplifiers are all hard wired. Audion’s intermediate power amplifier uses PX25 tubes. Like all our amplifiers they are hand built. The Silver Night Stereo range can reproduce subtleties and nuances in music that cannot be found in other amps of this price. Auto biased and have very conservative watt ratings which is equal to almost twice their rating if tested by competitors methods.

Audion Silver Night Anniversary PX25 is hand built and point to point hard wired (Air Wired©). We avoid the use of Chinese components where possible. This triode based stereo amp uses no (zero) feedback in the design.

The Silver Night range of amplifiers are the best known of the Audion products, and the ones that have won most awards, notably amp of the year in Japan 2010. The SN 300B hard wired was the amp originally reviewed by Sam Tellig that put Audion’s name onto the map.

This Silver Night Anniversary is best suited for use with loudspeakers of 89db or better efficiency. Ideally matched with our range of Proton or Electron cables. The amps deliver 8 watts into 8 ohms from a PX25.

Having a volume control on the front and stereo inputs on the rear means that a pre-amplifier is not necessary with this unit. The PX25 comes with KR PX25 tubes.

Integrated option (5 Stereo inputs is available). The chassis is black powder coated aluminum as is the transformer cover. The top plate and badge are mirror finished stainless steel.

The PX25 delivers slightly more power and presence as well as deeper bass and higher tops, the mid-range is incredibly sweet and controlled.
