From incredible professional and consumer out and out raves. From dealers who claim there’s no an amp below $10,000 USD that can compete with it. From the local snobbish 300B club who were slack jawed by its performance…The Super Sterling KT150, maybe the finest Single Ended KT150, easily gets our BEST in CLASS Award — TA
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.

Upgrade options and upgraded product categories direct from the factory.
We offer 2 upgrade classes for the Sterling Range.. The upgrade classes are
Insignia Class which uses a full silver wired audio path, better graded components again in the audio path, tantalum resistors in the critical places and WBT binding posts.
Excelsior Class uses the same as above but with the inclusion of Teflon/Tin foil V-caps, Internal Solid Silver wired Interconnect, a 43 way Stepped attenuator, better power supply capacitors and WBT RCA’s.
There are options on both classes for solid silver wound secondaries or primaries and secondaries on the output transformer.
