Audion Silver Night PX-25 Anniversary Stereo Amplifier

Exclusively imported by True Audiophile

8 watts?! Not a common tube? Right. We've had the ability to listen to low power legends and the PX-25 is definitely in a class of its own. Hands down its one of our favorite tubes. The PX-25 has been compared to having the best of a 45 and 2A3, but with more power. While the 300B was originally designed as a telephone tube, the PX-25 was always designed as an audio tube. Beautifully linear up and down the musical spectrum. We have supreme confidence in this tube and Audion's build quality, hand wound transformers, point to point and other uniquenesses in bringing a seriously legendary tube to life. -- Mini Review by True Audiophile 

Enjoy the Music Final thoughts "The Audion Silver Night PX-25 sets a very high standard at its price point. It is a balanced performer with no major weaknesses. Its expressive midrange is hard to walk away from. It images well and can generate stupendous dynamics in the context of a high-efficiency speaker. Need proof? Spend an evening with the Silver Night. You'll be glad you did." Read the full Review here.

These Audion amps are all hard wired. Audion's intermediate power amplifier, uses PX25 tubes. Like all their amplifiers they ares 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 amplifier is hand built and point to point hard wired (Air Wired©). Audion avoided the use of Chinese components where possible. This triode based stereo amp uses no (zero) feedback in the design.

The Audion 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 Audion Silver Night Anniversary is best suited for use with loudspeakers of 93db or better efficiency.  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. As the brand name is so well known this is the most popular selling amp in our line-up and the one that wins hearts and minds.

The current Audion Silver Night Anniversary is now 5th Generation product, originally being sold in 1987.

All Audion Stereo Amps are available as an integrated which provides 5 inputs and tape. Volume remote is also an option.

Optional upgrades are interstage capacitors and superior resistors. Prices quoted per request due to changing market pricing.
