Audion Sterling Mono Blocks PSE & PP

Sterling Parallel Single Ended and Push-Pull Monoblocks

5 Star Awarded

Audion Sterling power amplifier range

The Audion Sterling Anniversary range of hard-wired hand built mono-blocks consists of 4 models KT88 Parallel Single Ended and Push-Pull power amplifiers, and we have now included the powerful KT150 as an option on our Push Pull  and Parallel Single Ended power amplifiers.

There is a volume control on the front which means that a pre-amplifier is not always necessary. Being Auto biased means that both the PSE and PP amplifiers can take almost any KT88 (the amps are supplied with JJ tubes).

These Audion Sterling Anniversary edition Mono Blocks are very musical with smooth transients, good signal handling and tight response curves as well as good overall sonic performance.

These amplifiers are best suited for use with loudspeakers of 85db efficiency or better.

The Audion Sterling EL34 Anniversary Edition is a warm and dimensional-sounding amplifier with a potent lower midrange that does justice to the power range of an orchestra. It sang right out of the box and never misbehaved. Kudos to the Audion team for breathing new life into the venerable EL34 pentode. In my estimation, the Sterling EL34 represents a gift to music lovers everywhere. Highly recommended.

"Very round, smooth and toasty," but "well capable of enough resolution to easily distinguish Red Book CDs from their SACD cousins"; the midrange is "smooth and luxurious," but the bass has "neither the detailed control nor the slam of any solid-state integrated in [the Sterling Stereo EL34's] price range" -- no surprise., pulvinar dapibus leo. "Fully capable of refined tube splendor that's unanticipated at its price level."

The sound was a contrast, detailed and extremely musical. There was no slowness and desire to lull the listener, for which I dislike for a directly heated triode single end.

Every Sterling feels like it's punching well above its weight. So Good I bought one myself. More seasoned audiophiles will know that good amplification – no matter the topology – has no sound of its own. Don’t expect the thick syrup or golden hues of sub-$1000 Chinese units. There is no sickly/heavy sauce here. Neither is there porridge bass. Who said tubes are no hopeless below the waist? (Fools!) This Audion is the healthiest of extra virgin olive oil: light, transparent, clean. And fast. It is unburdened by ponderous, labouring low frequencies or musical weight gain. Its talents lie in 1. the ability to drive a wide range of loudspeakers and 2. the beautification of music. Each combination a winner.
