TANCHJIM SPACE II Portable DAC & Amplifier
The TANCHJIM SPACE II Portable DAC & Amplifier is a compact USB DAC/AMP designed for listeners who want high-resolution sound, powerful headphone amplification and flexible DSP tuning without carrying a bulky desktop setup.
At just 15.1 grams, SPACE II is small enough to pair with your smartphone, tablet or laptop and powerful enough to drive a wide range of IEMs and headphones. It combines a Dual CS43131 DAC architecture, TANCHJIM's self-developed Clean Bridge USB digital input chipset, 4.4mm balanced output, 3.5mm single-ended output and advanced online DSP functionality.
Whether you are listening to music, watching movies, gaming or simply looking for a better DAC for your phone or laptop, the SPACE II is designed to be an easy-to-carry, high-performance audio solution.
Dual CS43131 DAC for High-Resolution Audio
At the heart of the TANCHJIM SPACE II is a Dual CS43131 DAC chipset configuration designed to deliver clean, detailed and highly accurate digital-to-analogue conversion.
The dual-DAC architecture is combined with a carefully designed balanced digital and analogue circuit layout to help minimise interference and channel crosstalk. This allows SPACE II to deliver a clean background, strong channel separation and precise reproduction of your music.
It supports PCM audio up to 32-bit/384kHz and native DSD256, making it suitable for high-resolution music libraries and lossless streaming services.
What does this mean for everyday listening?
You can connect SPACE II to a compatible smartphone, tablet or laptop and use it as an external DAC and amplifier, bypassing the device's built-in audio hardware.
For audiophiles, this means you can get a more capable conversion and amplification stage without having to carry a traditional desktop DAC/amp.
TANCHJIM "Clean Bridge" USB Digital Input
TANCHJIM has developed its own Clean Bridge USB digital input chipset for SPACE II instead of relying solely on a generic USB interface solution.
The USB bridge handles digital audio data transmission between your source device and the DAC section, helping provide stable digital signal processing before conversion.
The result is a carefully engineered signal path designed around the Dual CS43131 DAC architecture.
SPACE II uses a USB Type-C input, making it compatible with modern smartphones, tablets, computers and other USB audio sources.
Powerful 4.4mm Balanced Output
Despite its compact size, the TANCHJIM SPACE II has a capable amplifier section with output power of up to 235mW @ 32Ω.
It provides two headphone outputs:
- 3.5mm Single-Ended
- 4.4mm Balanced
The 4.4mm balanced output provides up to 4Vrms, while the 3.5mm single-ended output provides up to 2Vrms.
This gives you greater flexibility depending on the IEM or headphone you are using.
The SPACE II is rated for headphones and IEMs with impedance from approximately 8–300Ω, making it suitable for everything from sensitive IEMs to many portable and full-size headphones.
Note: Output power requirements vary significantly between headphones and IEMs. Maximum output does not automatically mean every headphone will benefit from additional power.
3.5mm Output with In-Line Microphone Support
The 3.5mm output isn't just for listening.
SPACE II supports CTIA-standard in-line microphone input through its 3.5mm connection. This makes it particularly useful for gaming, voice communication and calls when using compatible wired earphones or headsets.
You can also use the 4.4mm balanced output for audio while using the 3.5mm connection for microphone input, making SPACE II a versatile option for gaming and communication setups.
Advanced Online DSP & TANCHJIM App Support
One of the biggest advantages of the SPACE II over a conventional USB DAC is its interactive DSP functionality.
Through compatible TANCHJIM software, users can explore and apply different sound profiles and tuning presets.
The online DSP ecosystem provides access to:
- Hi-Fi sound presets
- Official target curves
- Personalised sound filters
- Gaming presets
- Virtual soundstage profiles
- Community-created tuning profiles
This means you don't have to stick with one fixed sound signature.
Want a different tonal balance for a particular genre? You can experiment with available DSP profiles. Prefer a different sound for gaming or movies? Dedicated presets give you additional options.
For enthusiasts who enjoy experimenting with EQ and different tunings, the online DSP community adds another layer of flexibility to the SPACE II.
UAC 1.0 & UAC 2.0: Music and Gaming Compatibility
The TANCHJIM SPACE II supports both UAC 1.0 and UAC 2.0, with hardware-level switching between the two modes.
UAC 2.0 provides high-resolution USB audio compatibility with devices such as:
- Smartphones
- Tablets
- Windows PCs
- Mac computers
- Laptops
- Other compatible USB audio devices
UAC 1.0 compatibility makes SPACE II more versatile with gaming consoles and older USB audio hosts that may not support UAC 2.0.
This makes the SPACE II more than just a smartphone DAC—it can also function as a compact audio solution for gaming and multimedia setups.
Designed for IEMs and Headphones
With its combination of low distortion, high dynamic range and multiple output options, the SPACE II works particularly well with portable audio equipment.
For sensitive IEMs, the clean output and low distortion help preserve subtle details without unnecessarily colouring the sound.
For headphones that require more power, the 4.4mm balanced output delivers up to 235mW @ 32Ω, providing considerably more output capability than many basic USB-C dongles.
The compatible impedance range is approximately 8–300Ω, although actual performance will depend on the sensitivity and electrical characteristics of your specific headphones or IEMs.
Extremely Low Distortion & High Dynamic Range
The SPACE II is engineered for clean signal reproduction, with impressive measured specifications.
It offers:
- 132.2dB Dynamic Range
- 0.000156% THD+N
- Up to 116dB SINAD
These specifications indicate a very low-noise and low-distortion signal path, allowing the DAC/amp to reproduce music without adding significant unwanted distortion.
For listeners using high-resolution IEMs and headphones, this provides a technically clean foundation for detailed music playback.
Premium CNC-Machined Aluminium Construction
The SPACE II combines performance with a distinctive compact design.
Its chassis uses precision CNC-machined aluminium alloy, providing a sturdy and premium-feeling enclosure while keeping the weight extremely low.
One of its most recognisable design elements is the transparent window, which gives you a view of the internal circuit board and digital architecture.
Despite its compact dimensions of approximately 4.2 × 2.1 × 1.2cm, the SPACE II houses a complete Dual DAC, USB interface, DSP and amplifier system.
At approximately 15.1 grams, it adds very little weight to a smartphone or laptop setup.
Low Power Consumption
Portable DAC/AMPs need to balance performance with battery consumption.
The SPACE II is designed with efficiency in mind, consuming approximately 0.4W at a 32Ω load.
This makes it suitable for everyday portable listening without the power requirements associated with larger desktop DAC/AMPs.
Who Is the TANCHJIM SPACE II For?
The SPACE II is a particularly good choice if you:
- Want a high-quality USB DAC for your smartphone or laptop
- Use IEMs or headphones and want better amplification
- Want a 4.4mm balanced portable DAC
- Need both 3.5mm and 4.4mm outputs
- Listen to high-resolution PCM and DSD music
- Want DSP/EQ tuning flexibility
- Need a DAC that can also work with gaming setups
- Want UAC 1.0 compatibility for supported gaming consoles
- Want microphone support for compatible 3.5mm headsets
- Prefer a very small and lightweight DAC/AMP
- Want a technically clean DAC without carrying a desktop unit
Is TANCHJIM SPACE II Good for Gaming?
Yes. SPACE II is designed to work beyond traditional music playback.
Its UAC 1.0 compatibility, 3.5mm microphone support and DSP functionality make it suitable for compatible gaming setups.
The available gaming and virtual soundstage DSP profiles can also be useful when you want to experiment with a wider or differently positioned presentation during gaming.
For competitive gaming, the actual experience will still depend heavily on your IEM/headphone, game audio mix and chosen DSP profile.
Is the TANCHJIM SPACE II Good for Smartphones?
Yes. The USB Type-C connection makes SPACE II a natural companion for modern USB-C smartphones and tablets that support USB audio.
Instead of depending entirely on the phone's internal audio hardware, SPACE II handles digital-to-analogue conversion and headphone amplification externally.
It is particularly useful if your phone does not have a headphone jack or if you want a more capable output stage for your IEMs or headphones.
3.5mm vs 4.4mm: Which Output Should You Use?
3.5mm Single-Ended:
Ideal for conventional wired earphones, IEMs and headphones with a standard 3.5mm termination. It also provides CTIA microphone support.
4.4mm Balanced:
Designed for headphones and IEMs equipped with a 4.4mm balanced cable. It provides the higher-power output of up to 4Vrms / 235mW @ 32Ω.
If your IEM or headphone already has a properly wired 4.4mm balanced cable, the 4.4mm output gives you access to the SPACE II's higher output capability.

It feel like music stunning
Thank you Audio Store for the free gift. I am elated.
I am extremely satisfied with EarAudio 4.4 mm Male to 3.5 mm female adapter cable. The quality of the product is top notch and well made. I am now able to use my 3.5 mm cable with my iems plugged to my dac. Recommended!
It's a good headphone under this budget and leads give me a reliable delivery products as I satisfied from audio stores and if I buy remote sound products I will buy from audio stores and the very good very product in the budget 1200 rupees it's a good like premium and classic IEM IN EAR MONITOR.
Great sound quality with best in class clarity in beats and sounds.
Great bass texture, vocals and mids are clear and sound good, it has good details and sounds clean overall. Takes eq well. Major step up from wireless earbuds in sound quality. Product got delivered in 5 days dtdc, nicely packed. Cable and tips are not the best, forgiveable for the price tho.
Product is genuine but the main thing is the delivery time, it's awesome, they're really quick in this thing and also pretty genuine store.
My review is after 4 days of listening. The packaging and delivery was great. This is my first audiophile IEM with the latest planar driver tech. I own the Tangzu Waner SG and Kefine Klean as entry level IEMs.
Astralis IEM plays any genre of music flawlessly with fast transients, rich-textured bass, perfect vocals, smooth treble with a touch of airyness and sparkle which is non-fatiguing. As I am treble sensitive, these can be worn comfortably for longer duration.
Please note they might sound low in the beginning, the volume needs to be cranked up a bit as they require a tad bit amplification with the DAC. The included DAC is perfectly fine even if you don't own any other DAC. Works perfectly with phone or laptop; though using the DAC is recommended to get the full potential of this IEM.
Coming to the sound output with the DACs:
With the included DT01 Pro - More neutral presentation with soundstage which is mostly centre-staged.
With the Audiocular Note - Bass which has more punch + rumble and better energetic presentation with soundstage which is wider and has a better sense of openness.
Among the DACs, the Audiocular Note brings out the full potential of the Astralis.
Thanks again to The Audio Store for a great packaging and delivery experience.
This iem sounds very good.Good for music and gaming,i loved it and I'm satisfied for buying this.
Worth buying it.
The KZ Castor Pro is one of the best entry-level IEMs I've used in this price range. The sound quality is impressive, with clear vocals, detailed instruments, and punchy bass that doesn't overpower the mids. It offers excellent clarity, making every song enjoyable.
It's also a fantastic choice for beginners who want to experience audiophile-grade sound without spending a lot of money. Whether you're listening to music, watching movies, gaming, or enjoying podcasts, the audio feels clean and immersive.
The comfort is good for long listening sessions, and the build quality feels solid. If you pair it with a decent DAC, the sound becomes even better with improved detail and separation.
Overall, I highly recommend the KZ Castor Pro to anyone looking for an affordable entry-level IEM. It offers outstanding value for money and is a great starting point for anyone entering the audiophile hobby.
I can catch all the little details in songs with the hi-res audio. I chose these earphones to enhance my movie-watching experience, and they do the job. I watched a bunch of scenes from 'Dhurandhar: The Revenge' over and over, and these IEMs gave me a hell of an experience! It felt like I was watching this movie in a theatre for the first time.
Big thanks to The Audio Store for bringing these experiences to us!
Overall very Good product but value for money is High
Excellent IEMs for the price. The sound quality is clear and detailed, with great instrument separation and balanced tuning. They're also comfortable for long listening sessions. Definitely one of the best options in this price range.
Delivery was on time, packing was nice. Product is well producted. Iems themselves are good and best in this budget range. But require specific frequency and players to get most our of them.
for me this is a game changer it helped me a lot .
value for money
it supports in all devices including macbook and ios devices .i am really satified with purchase . thank you
The Audiocular Beam Portable DAC is definitely worth it. The metal build along with the braided cable feels reassuring and sturdy, and the DAC never felt considerably warm even during longer listening sessions. It also maintains a somewhat neutral sound signature as far as I can tell, and noticeably increases the perceived volume of my KZ Castor Pros. Furthermore, I personally haven't heard any hissing noises on my IEMs, if that is something you're worried about. Finally, the red LED ring light is a cool touch, if a bit gimmicky and distracting during late-night listening sessions, but the bonus Audiocular carrying pouch along with the Type-A converter included in the package is what makes this a great deal. If you're looking for a DAC around ₹1,000, you should certainly consider the Audiocular Beam.
