Announcing Allnic’s newest stereo amplifier
Another among recently and soon to be released
world-class - and world’s first - audio products
ALLNIC AUDIO’S NEW
A-2000 MK3
Push-Pull KT170 stereo power amplifier
Industry-leading sound quality combined with stately industrial design
Like the recently released M-3000 MK3 mono-blocks you can read about just below, the new A-2000 MK3 features the high-power and musical KT170 tube. Again, like the M-3000 MK3 mono-blocks, the A-2000 MK3 features “on-the-fly” pentode/triode switching but outputs half the power of a pair of M-3000s, with 120 watts per channel in pentode and 60 in triode.
Like all Allnic’s power amps, the power tubes are expertly matched to gain tubes and output transformers by Allnic’s KS Park; Allnic’s power amps are not simple re-workings of old circuit designs. Advanced solid-state rectification and regulation – meaning less heat output among other positive features, a massive power transformer and a modest, natural level of negative feedback allow for simplicity of use, reliability and superb linearity. The sum of all these features is incredible speed, exceptional drive and bass, low distortion, and rock-solid stability - together meaning world-class transparency, dynamics, realism, and long-term reliability, with power to drive almost any speaker.
The A-2000 MK3 can be ordered from the factory with either 8 and 4 or 8 and 16 ohm speaker connections, and with both single-ended and balanced inputs provides flexible connectivity. Though it is heavy at about 80 pounds, ergonomics have been carefully considered in the A-2000 MK3’s chassis design: integrated, solid handles are a particularly useful feature.
If you want Allnic’s exceptional sound quality but do not need the 240 watts per channel that a pair of M-3000 MK3 monoblocks output in pentode mode, or you simply do not have space for two large amps, the A-2000 MK3 may be your perfect choice.
The A-2000 MK3 is available in either black or silver, and whichever finish you like, now is a good time to explore purchasing this new Allnic masterpiece. You might have noticed that the A-2000 MK3 is the model for the banner at the top of this page, and yes, the sale the banner references includes the A-2000 MK3 at a time-limited introductory price.

INTRODUCING ALLNIC’S NEW, POWERFUL, REFINED
M-3000 MK3
KT170 MONOBLOCKS!
Redesigned for the incredible KT170 beam-tetrode power tube, Allnic’s new M-3000 MK3 monoblocks take vacuum tube power and finesse to new heights of excellence. Like the MK2, the MK3 is also a parallel push-pull design, but changing from the KT150 power tube to the KT170 nets more power and even more resolution and transparency. Whereas the MK2 netted 200 watts per amp in pentode mode and more than 90 “SET-like” watts in triode, the MK3 supplies 240 watts in pentode and more than 100 in triode. Of course, like all Allnic’s power amps, that output is also matched by exceptional driving force thanks to Allnic’s KS Park’s optimized circuit design and painstaking gain tube/transformer matching. Like the MK2, the MK3 can also be switched between pentode and triode modes by the press of a button on the front of the chassis - “on-the-fly”.
Much of the improved M-3000 MK3’s refinement is due to the circuit changes Mr. Park made for the MK3 to obtain the best performance from the KT170s. In addition to much larger power and output transformers, which are, of course, Allnic’s hallmark in-house manufactured permalloy specialties, the driver tubes have been changed to the very stable and reliable 5654 in the input position (providing many options for tube-rolling among brands and vintages) to the 6S4 (or 6S4A) triode in the critical second gain position – replacing the triode wired, and increasingly difficult to find, E282F pentode tube wired in triode. Various manufacturers also made the 6S4 over many decades so can also be “rolled”; and as a “pure” triode, it contributes even more to the purity, the crystalline clarity and exemplary resolution of the M-3000 MK3.
In addition to the above features, the new M-3000 MK3 monoblocks provide:
⦁ Analogue power tube current monitoring meters
⦁ Exceptionally easy bias controls
⦁ Soft start circuitry
⦁ Individual fuse protection for power tubes
⦁ Dual inputs, one RCA and one XLR
⦁ 4 and 8 ohm speaker terminals (8 and 16 by factory order)
As can be expected, the M-3000 MK3 monoblocks will pair especially well with any of Allnic’s line-stage preamplifiers, from the award winning “little giant” L-6500
to the tour de force, pure direct-heated triode L-8000 DHT.
The M-3000 MK3 monoblocks are a vacuum tube-based marvel of audio engineering. Their power, stability, and clarity are matched by their weight; at 36kg, almost 80lbs, per chassis, caution is advised when you are moving them around. Fortunately, the design also features handles – in the right places - to provide a great deal of ergonomic efficiency for moving them around safely.
The M-3000 MK3s will drive essentially any speaker on the market with outstanding results. If you need significant power and still want all the qualities, the beauty of life-like presentation of a world-class tube power amplifier, the M-3000 MK3s might be for you.

Push-Pull or Single-Ended Triode?
YOUR EARS, YOUR MUSIC, YOUR CHOICE!
Our physical characteristics and our preferences, our tastes, determine many important aspects of our lives, affecting our choices in a wide variety of ways. For example, we all hear and listen differently, and we all have our music preferences, and these personal, music listening-related capacities, traits, likes and dislikes, send us one direction or another when selecting audio gear. Some most like solid-state, while others prefer vacuum tube-based circuits. Among the latter, where we are when we’re talking about Allnic products, some prefer the sound of one kind of power tube and circuit, others something different.
M-2500 Push-Pull Monoblocks (300B version)
Fortunately, KS Park of Allnic understands all of these, and over more than 30 years in the industry has produced a wide range of products among the best of their types, giving us an outstanding number of superb choices. In the last couple of years, Allnic introduced two models of both Push-Pull and Single-Ended Triode (SET) monoblocks that not only give us the choice between those two types of circuits, but also among a range of power tubes.
A-2500 SET monoblocks (845 version)
Regardless of which appeals to an individual, one can be certain that what the amplifer of one’s choice will do is make REAL MUSIC at home.
The power amplifiers under discussion here and shown above are the A-2500 SET and M-2500 Push-Pull monoblocks.
You probably noticed some similarities in appearance between the A-2500 and M-2500. Most obviously, the A-2500 and M-2500 monoblocks share the same chassis – to which the number “2500” refers. The casework and size are the same, and the monoblocks of each pair are mirror images of each other. So, what do the “A” vs. “M” designations signify? Allnic uses the “M” to designate “push-pull” circuit designs, while “A” has been the designation for SET amps. In short, then, the M-2500 and the A-2500 share the same chassis, but the M-2500 is a push-pull amplifier while the A-2500 is a SET amplifier.
They look similar. Are there other similarities? What are the differences?
M-2500 Monoblocks:
Push-Pull with choice of 300B, PX25 or KT150 power tubes
I have owned many tube amplifier designs over the years, and historically the push-pull type has never been my favorite. Each design approach has its strengths and weaknesses. The “power-tube flexible” M-2500, though, has hit the sweet spot between SET and typical push-pull amplifiers: it maintains the micro detailing, textural and overall finesse across the midrange that SET designs are known for while providing the dynamics, slam factor and extended and focused bass of a push-pull amp.
M-2500 - rear panel view
Bass control with a pentode push-pull presents with optimal accuracy. I suspect the SET characteristics can be attributed to the direct-heated vacuum tube rectification. In the M-2500, an NOS 5U4G or 5U4GB full-wave rectifier tube replaces the semiconductor diode in the rectification circuit used in the M-3000 MKII and Allnic’s other traditional push-pull amplifiers.
What the M-2500 provides is the power and dynamism of the Push-Pull amplifier combined with more than just a touch of the spaciousness, and 3D solidity and imaging typical of SET amplifiers – maybe not quite so surprising with the 300B or PX25 power tubes one can choose (30 and 20 watts output, respectively), but more so with the KT150 option – at 100 watts output!
I’m not alone in my assessment:
The M-2500s passed all tests with flying colours. Simply, they allowed the components upstream to sing & play with abandon.

A-2500 Monoblocks:
Single-Ended Triode (SET) with choice of 845 or 211 power tubes
The A-2500 possess all the positive, well-loved, sound quality characteristics of the SET amplifier, a 3D and almost tactile soundstage, with a very spacious, airy, detailed, and outstandingly musical and emotionally engaging presentation. Unlike many SET amps, however, the A-2500 has incredible drive – a feature of KS Park’s circuit design which pairs tubes (input, driver, and output – and in the case of these two models, rectifiers) and Allnic factory manufactured permalloy-based output transformers to perfection. With either of the classic 211 or the 845 (both with 20 watts output) combined with an NOS 5R4WGA rectifier, the powerful, articulate, and detailed bass presentation in no way leaves me wanting. The 845’s low-frequency robustness is on par with my favorite power tube’s, the PX25 (an option for the M-2500).
A-2500 with 211 power tube
As the M-2500 exhibits a good dose of the “magic” of SET amps, the A-2500 has speed, dynamics, and rhythmic propulsion more than just a bit reminiscent of what is commonly associated with Push-Pull amps only. With the A-2500, prepare to be surprised by the excellence of the expected SET sound - and the unexpected benefits of real power-drive.
A-2500 – rear panel view
The A-2500 and M-2500 each have all the typical positive qualities of the type of circuit they employ but with sound quality characteristics that in many ways give us the best of both. They differ in many ways, but as I noted at the beginning of this post, what they can both deliver is exceptional musicality.
Which kind of musical “reality” do you prefer? The choice is yours!
I should add that Allnic also makes the A-5000 Direct-Heated Triode (DHT) 300B monoblocks.
A-5000 DHT monoblocks
A-5000 DHT features Allnic In-house manufactured HL2 and RS242 triodes! 300B by Allnic in 2023!
These 10 watt output SET monoblocks have a different chassis from the A-2500/M-2500 (hence the “5000” designation), but what really “sets” the A-5000 apart is the use of all DHT tubes, some quite rare. Consequently, it is a unique, very “purist”, and exquisite sounding product, the very best of the SET sound.
To ensure supply, Allnic is now producing - in-house - stable, reliable and beautiful sounding HL2 and RS242 tubes, the input and driver tubes in the A-5000.
Yet another choice...
Here is a summary of the differences between the M-2500 and A-2500, and of the range of tube type/output power available for each.
M-2500 Monoblock Amplifier (Configuration at the factory only):
PX25 - 1st Stage 5654, 2nd Stage 12A4, 5U4G/GB Rectifier and PX25 x 2 power tube. 20W Continuous. Triodes in Push-Pull configuration.
300B - 1st Stage 6485, 2nd Stage 12A4, 5U4G/GB Rectifier and 300B x 2 power tube. 30W Continuous. Triodes in Push-Pull configuration.
KT150 - 1st Stage 5654, 2nd Stage 6S4, 5U4G/GB Rectifier and KT150 x 2. 100W Continuous. Pentodes (Beam-tetrodes) in Push-Pull configuration.
A-2500 Monoblock Amplifier (Configuration at the factory only):
211 - 1st Stage 6CM7, 5R4WGA Rectifier and 211 x 1 power tube. 20W Continuous Pure SET design.
845 - 1st Stage 6DR7, 5R4WGA Rectifier and 845 x 1 power tube. 20W Continuous Pure SET design.
With the individual tube biasing, pairing is not necessary. Allnic circuit designs do not overdrive their tubes, and they tend to last a very long time. The M-2500 and A-2500 amps appear to retain this benefit.
To give you at least a rough idea of which of the “2500” monoblock amps might suit your requirements for output power, you can find a handy calculator for amplifier power requirements for various speaker sensitivities and SPL at:
https://www.crownaudio.com/en/tools/calculators#amp_power_required
Whatever choice you make, I am convinced you won’t be disappointed. Both monoblock amplifiers are available with approximately a two-week lead time to delivery.
Prices:
A-2500 SET: $19,500 USD.
M-2500 Push-Pull:
300B/PX25: $19,500
KT150: $18,000 (Sale!)
Since options are always great, if the M-2500 and A-2500 monoblocks are not exactly what you’re looking for, perhaps this is:
A-2000 25th Anniversary SE (Special Edition)
We still have a few of the special, “hot-rodded” edition of Allnic’s fantastic 100 watts/channel KT150 based stereo power amps available. This has to be one of the finest power amps available at anywhere near the price: $6,750! This is closeout pricing at1/2 cost compared to the newly released A-2000 MK3!!
The A-2000 25th Anniversary is a 100 watt/channel powerhouse and paragon of clarity and finesse. With the modifications it sounds even better, and for the price, we think nothing will be able to touch it. It’s a great way to end the A-2000 25th Anniversary’s production run, and a great opportunity, limited by number of course, for anyone wanting a brand new Allnic power amp, one that can drive virtually any speaker, “for a song”, so to speak.
Allnic Audio A-2000 25th Anniversary/SE is a 100 watt (KT150 beam tetrode) push-pull, stereo power amplifier. Like its integrated amplifier brother, the T-2000, the A-2000 25th Anniversary/SE is pentode/triode switchable “on-the-fly”, providing more than 50 watts in SET sounding triode mode. The A-2000 25th Anniversary/SE offers stable, resolute power in the proverbial velvet glove, along with amazing, revelatory clarity, incredible dynamics and drive, articulate and powerful bass, and standard setting low noise and distortion.
Review and award for the standard, not SE, A-2000 25th Anniversary – July 2021!
Part-Time Audiophile names the A-2000 an Editor’s Choice!
“It’s rare for me to review a product like this which is just so thoroughly sorted, and at what I find to be a very fair price…
If you’re in the market for an amp that does what the modern 100W per channel solid-state stereo amplifier purported to do; power anything big or small, do so quietly and with great character and flat frequency response, I’m here to tell you that you can do one better, and even get those magical glowing vacuum-sealed bottles while you’re at it. If you have an opportunity to lay ears on this amp—don’t miss it.”
