Introduction:-
Anode Acoustics is a Hi-Fi Indian brand that makes some brilliant hand-crafted audio amplifiers and other studio-related gears. Anode Acoustics have a history of manufacturing high-quality studio equipment mainly consisting of tube and solid-state amplifiers. But a few years back Nitin Ji from Anode Acoustics also started making headphone amplifiers with their very first Anode Acoustics #1 tube headphone amplifier. I personally have a short experience with the #1(with HD600) that I got to try at an audio meet in my city a year back. Since then Anode Acoustics has added a few more additions to the headphone amplifier range with three more products, #2, #3, and #4. #3 is an OTL tube amplifier while #2 and #4 are both solid-state amplifiers but both working on different technologies.
Both the #4 and #2 HP amps are based on different technologies, both have entirely different sound signatures, both have their own benefits and cons. #2 is based on MOSFET Technology and #4 is built on BJT Power Output Transistors, #4 has a natural, reference-grade tuning and #2 has a smooth, soft, tube touch to the sound. Anode Acoustics #2 is available to purchase for 25k INR(approx 350$) and #4 is available for 22k INR(approx 300$). Today I am going to share my opinion about their second solid-state amplifier, the Anode Acoustics #2.
Disclaimer:-
The #2 and #4 were sent to me for an audition by Nitin Ji from Anode Acoustics. I am not benefiting in any way from Anode Acoustics in return for this review. All thoughts and impressions in this post are based on my own experience with the amplifier. If you have any questions regarding its technology or want to order one, contact Anode Acoustics on their Facebook page

Design & Build Quality:-
Similar to Anode #4, the #2 has a simple and sturdy design made with 1.2m thick powder-coated steel. It has an aluminum front panel with a glossy plate that has Anode Acoustics printed on it. The 3.5mm connector here has a push-button mechanism, it locks the headphone socket inside and one has to push the button in order to pull out the headphone. The volume knob is right next to the quarter-inch headphone socket. On the back, we have high-quality RCA connectors and a power socket. The only noticeable light on the amp is on the side right under the power switch which gets on when we turn on the amplifier.
Overall the Anode #2 is built like a tank, it looks excellent with a polished aluminum front plate and a heavy build. I never faced it getting hot even after long continuous usage(up to 5-7 hours at a single time).
Chain:-
My source for this review is xDuoo XD-05 Bal line-out to the Anode #2 amplifier. I used Sennheiser HD600 and Unique Melody Mirage as my main headphones and earphones for this review.
Sound Quality:-
Even though both the #2 and #4 are from the same manufacturer, they both have an entirely different sound signature. On one hand where #4 has a reference-grade natural tone, on the other the #2 has a sweet, soft, warm touch to the output that reminds me of tube amplifiers. Yes to me, It presents the output in a very musical, melodious manner that complements the sound with thick lower-end, lush vocals, and smooth treble frequencies. Instrument notes have good air between them and also a good sense of weight to them.
Similar to #4, #2 is extremely powerful. It powers my HD600 at around 30-35% on the volume pot only. For items such as the Unique Melody Mirage, about 10% on the volume pot is more than enough to bring the pair to life.
Bass:-
#2 has a fantastic bass response, it has its main emphasis on the mid-bass portion with slams hitting right to the core. No, it doesn’t have overpowering bass, rather has a very clean, refined bass response that complements the other frequencies well with its punchy presentation. Sub-bass presence can also be felt with good depths and powerful rumble.
Mids:-
Mid-range response is kind of the finest mood here with a forward signature. Even though it is forward it doesn’t make the vocals go shouty or harsh even at loud volume. Both the male and female vocals carry a lovely, soft tone to them that it is a pleasure listening to artists like Damien Rice, Gloria Gaynor, Yao Si Ting with #2 in the chain. Acoustic guitar, Piano, and other instruments show a rich presentation with a good sense of weight in their strings/keys. Overall, a very lovely mid-range with the #2.
Treble:-
Treble portion has good energy, a smooth, non-fatiguing approach. With the warm nature of the amplifier, I am pretty sure it will benefit earphones/headphones with bright treble tuning. The high-frequencies have good detail and separation with good airiness between them. There is no noticeable fatigue or sibilance in the output, instruments such as Violins, Electric Guitars have an excellent presentation with good clarity between the notes.
Soundstage & Imaging:-
Dynamics such as layering, imaging of instruments in the output are quite produced quite beautifully. Obviously, the output is very clean and powerful it gives ample space for the headphones/earphones to shine their best. In terms of soundstage, the overall presentation is intimately similar to the #4 but has a better sense of depth here with the #2.
#2 Vs #4, Which one is their best Solid State Amp:-
#2 and #4 are both excellent at their own respective places. #4 delivers a natural tone and true, pure sound while #2 adds a warm, smooth tone to the music. #2 will definitely suit bright headphones too, taming the harsh highs with its loving touch of smoothness, #4 will present the output as it is. Here are the key points between the two.
>#2 is made on MOSFET technology, #4 is based on BJT Transistors.
>Both the #2 and #4 are tremendously powerful headphone amplifiers.
>#2 has a warm, soft tuning while #4 has a pure, natural sound tuning.
>#2 produces better tonal weight, more air in instruments.
>Both have an intimate soundstage presentation but #2 has better depth.
>Driving power with both the amplifiers is identical.
>#2 costs 25K INR(roughly 350$), #4 costs 22K INR(300$ approx).
Some cons with #2:-
>Staging is intimate in terms of width. (Not a con as such depends on person to person).
>No pre-amp, no balanced connection support.
A Few Final Words:-
Anode Acoustics #2 does best what it is made to do!! It’s an extremely powerful amplifier that holds enough juice to power up even demanding cans with ease. Even for an HD600 that is a 300ohm can, I just never had to go above 35% on the volume pot. To be very honest I enjoyed both the #2 and #4 amplifiers from Anode Acoustics, choosing between them is super easy too. Both the amps have different sound signatures so, users can choose the one that falls right under their listening preferences. As I have stated many times in this review, #2 for a warm, soft sound that presents a sweet melodious sound, and #4 for a natural & reference-grade sound.
