Audion Sterling Product Range
Sterling Stereo, Stereo Integrated, Parallel Single Ended and Push-Pull Monoblocks
Audion Sterling power amplifier range
The Audion Sterling Range consists of Single Ended Stereo & Stereo Integrated, Parallel Single Ended and Push-Pull Mono-block power amplifiers, with a choice of EL34, KT88, KT120 and KT150 valves. With power ranging from 12 watts per channel pure class A from our basic entry level Mk1 PCB Sterling valve stereo power amp to over 45 watts per channel from our KT88 push-pull model.
The Sterling range is our entry level range, however despite being affordable. Most audiophiles know that the best amplifiers have no “sound” of their own, The Sterling’s do just that, producing fast, tight transparent and clean with a beautiful inky blackness where it counts. No bloated bass or “tinny top end”
All of the Sterling amplifiers are punchy and certainly feel like they are truly capable of working with a wide range of loudspeakers.
“Each Sterling is a winner” – Johnny Darko
Where possible we avoid the use of Chinese components. These Pentode based amplifiers use unique ultra-linear circuits and of course our own output transformers. See the tabs below for list of amplifiers and options to suit your needs
Audion Sterling EL34 Anniversary Stereo
Audion Sterling amplifiers come with a wide range of options, starting with our Mk1 printed circuit board EL34 stereo amplifier right up to our Anniversary KT88 Mono-block Power amplifiers and represent our entry level models.
The range consists of 12 different variations of the Sterling, with power outputs from 12 – 45 watts and 4 different circuit topologies.
The hard wired (Air Wired) 30th Anniversary amplifiers are wired point to point. All of of our amplifiers have a volume control on the front which negates the need for a pre-amplifier in most cases. Our stereo integrated power amplifiers even have a 5 stereo channel passive pre-amplifier built in so you can use up to 5 line level inputs. These amps even have an un-attenuated output for feeding directly to a tape recorder or active sub-woofer or even to another amp for bi-amping. All of our single ended designs use a unique ultra-linear circuit and all Sterling power amps use a small amount of negative feedback to make the pentode valves work properly.
All of our Sterling models are auto-biased so do not need regular bias changing or complicated setting up.
Our amps are ideally suited to loudspeakers of 89db or greater efficiency except for our mono-block versions that can cope with lower efficiency.
Sonically, The Pentode valves used in the Sterling Range are robust and have a fantastic weight and clarity and the larger KT88, KT120 and KT150 are well suited to more difficult loads.
The chassis is made of military grade aluminium, with a durable black powder coated finish. The top plate and badge are finished with mirror polished stainless steel.
Technical specifications for all products in this range.
Warranty: 2 years return to base. Valves 6 months.
