Audion Black Shadow 2 Mono-Blocks: Effortless Sound and Uncompromising Performance
The Audion Black Shadow 2 mono-block amplifiers have been meticulously re-designed to deliver exceptional audio quality. Key features include:
Single-Ended 845 Output Valve: The heart of the Black Shadow 2 is the mighty 845 output valve, operating in pure Class A mode. With zero negative feedback, it ensures a natural and uncoloured sound.
Enhanced Components and Circuitry:
An additional buffer stage improves transient response.
Upgraded mains and output transformers enhance overall performance.
Slow start high tension (HT) protects the valve life.
High-quality components, including large polypropylene capacitors and bypass/decoupling capacitors, contribute to fast and fluid transient handling.
Hand-Built Craftsmanship:
Each amplifier is meticulously hand-built and hard-wired using solid silver (99.999%) in most of the audio path.
Exceptional attention to detail ensures optimal signal integrity.
Powerful Output:
The directly heated 845 triode produces a substantial 25 watts of Class A power.
This power output is suitable for driving a wide range of loudspeakers, offering impressive grip, agility, dynamics, and realism.
Effortless Sound:
Reviewers describe the Audion Black Shadow 2 as “effortless.” There’s no sense of electronics interfering with the music—just pure, unadulterated sound.
Low-frequency tonality and flow are exceptional, creating a captivating listening experience.
Internal Improvements:
The MK2 Black Shadow features an updated internal chassis layout, optimizing build quality and component placement.
Magnetic shielding around the transformers further reduces noise, resulting in a blacker soundstage.
Critical Acclaim:
Nicholas Ripley of Hifi Plus praises the Black Shadow 2, emphasizing its seductive and captivating qualities.
Musicians seem to come alive through these amplifiers, making them a favorite among discerning audiophiles.
In summary, the Audion Black Shadow 2 combines craftsmanship, power, and musicality, making it an irresistible choice for serious audio enthusiasts. Experience the effortless sound that wins hearts and reveals hidden musical details
“That’s the word that best sums up the sound of the Audion Black Shadow 2 – effortless. There is no sense of electronics getting in the way of the sound, more like musicians have been fed into your loudspeakers” – Nicholas Riply – Hifi Plus
“the Audion Black Shadow 2’s show just how seductive they can be. This is a beguiling amplifier, with the sort of effortless sound that wins people over.” Nicholas Ripley. Hifi+ December 2015.

Description
The Black Shadow 845 hard wired (point to point) Single Ended amplifier comes with Shuguang 845’s as standard but can also be supplied with a choice of 845 tubes upon request. This amp will work with most speakers over of 83 – 4db efficiency. The Black Shadow Mk2 delivers 25 watts of pure Class “A” power into 8 ohms The amp has both 4 and 8 ohm outputs.
Having a volume control on the front of both mono-blocks and mono inputs on the rear means that a pre-amplifier is not necessary with this unit if you only use one line level source, but we do recommend that a pre-amp is used. The Black Shadow is auto biased which means that it will accept almost any 845 tube (The amps are supplied with Shuguang 845’s . This amplifier is meticulously hand built and hard wired point to point by our artisans.
Upgrade options are available for this model, see upgrade options tabs.
To provide the fastest transient response possible, solid-state rectification is used, and the design and its implementation ensures phase coherent harmonic structure throughout the frequency spectrum. The 845 output tubes used are well within their specified performance envelope to ensure low distortion and optimum sound quality, as well as extended tube life. .
Our output transformers are wound in-house to our exacting standards and many of the components are either made by us or specifically for us. We use Shuguang 845’s and NOS E182CC & NOS Russian 6H23N. The Black Shadows are designed for difficult loads, loads of power and yet very musical.
Many of our high end products are offered with bespoke options, in fact many of our customers who order these products have a good idea what they want in their amplifiers in terms of final sound and final look. So with that in mind, we can pretty well tailor the high end amplifiers to suit your requirements. You can of course go with our recommendation based on your system.
We offer our stock level Black Shadow 2 with 3 upgrade options (which are available on all of our amplifiers), that being Insignia, Excelsior and Signature Reference classes.
This is a great starting point and one that many people opt for as it is an “off the shelf” package. Often however when tailoring your amp for your musical tastes you may wish to change the stock upgrade component for something that you know works for your ears.
“We can do this, just ask (info@audion.co.uk)alternatively as well with our high end products you may wish to customise the look more to your specification. We have the ability to gold and silver plate, powder coat and produce via cnc machinery a variety of looks and finishes. These options do take time however, are an additional cost and only available on our high end range from Insignia and upwards.” We do feel that the upgrade options add considerably to your sound investment.”

Audion Black Shadow Mk2 Amplifier – Absolute Sound
Audion Black Shadow 2 – Hifi Plus
The Absolute Sound
SET amps aren’t for everyone, but the Audion Black Shadow 2’s show just how seductive they can be. This is a beguiling amplifier, with the sort of effortless sound that wins people over
"Very round, smooth and toasty," but "well capable of enough resolution to easily distinguish Red Book CDs from their SACD cousins"
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.
My Hi-End
The first track 「Little Black Lake」 has a large piano performance. Every key can hit the heart directly. The density of the bass is both high and Thick, the clarity of the sound form makes the music more authentic. The second track 「Soothing Your Soul」 has more jazz drum accompaniment, whether it is under the bass drum or the percussion of the alto drum is deep and elastic, combined with the piano and vocals There is a very complete sound field and sound part. Audion's front and rear extensions fully demonstrate the advantages of high-quality vacuum tube amplifiers, weight, warmth, dense and detailed natural sense, and music without loss of detail. Probably the reason why many people cannot extricate vacuum tube amplifiers. I believe not only many People are fascinated by this, and many people are deeply trapped in the charm of Audion.
