I’m trying to find out how to replace the volume pot on my zen can sig. It’s so hard to see at night. I have some guitar knobs that are way nicer looking I’d like to put on it. Just swapped out the knob on my schiit Midgard and i can actually see it at night now.

However, there is no set screw on the zen cans knob and I don’t want to try and force off the knob unless I know I’m not going to break the thing.

Hi There,

The Knob is a pull-off, just place a small screwdriver (Flathead) in the space between the unit and the knob, give it a little pry, and then apply firm straight pull-out pressure and the knob should come off!

Cheers!!

Thanks so much for the immediate reply! worked like a charm. I may like the color orange a bit much lol. The white triangle on the knob is so much easier to see in low light.

Hi All!

Until now, we have released headphone-specific ZEN Signature headphone amps: 6XX HFM & MZ99

We're now proud to announce the ZEN CAN Signature - The newest addition to the ZEN Signature range!

1694015463185.png

For IEMs and headphones with audiophile-grade components for superior sound.

Signature Sound. Tailored by iFi.​

The ZEN CAN Signature is an upgraded version of the original, award-winning ZEN CAN headphone amplifier.
Design for IEMs and headphones with audiophile-grade components for superior sound.

1694015570802.png

Enhanced circuitry. Premium components. Signature Sound.​

The original ZEN CAN, our all-analogue headphone amplifier, excelled at driving demanding headphone loads with its balanced circuit design, extremely low distortion, and exceptional sonics. The ZEN CAN Signature takes this design further, featuring enhanced circuitry and audiophile-grade components.

Its balanced, symmetrical dual-mono circuitry can deliver 1890mW (11.0V) into 64-ohm loads and offer over 15V to loads of 600 ohms or higher, all through its balanced output.

Why ZEN CAN Signature? Because More Power Matters.​

Laptops and smartphones typically have a low power output of less than 1.0V. With a quality pair of headphones, you often find yourself running out of power, never truly experiencing their full potential.
Connect your laptop, phone, or DAC to the ZEN CAN Signature and plug in your headphones. Delivering 50 times more power, you’ll finally hear what you’ve been missing.
However, the ZEN CAN Signature offers more than just power; it also delivers warm and exceptional sound quality. This is thanks to its Class A discrete balanced circuitry, inherited from the flagship Pro iCAN headphone amplifier.

3 In, 3 Out. Free to Connect.​

The ZEN CAN Signature offers a range of input options, including stereo RCA, 3.5mm single-ended, and 4.4mm balanced inputs, making it versatile enough to connect with your laptops, phones, or DACs.

For output, it provides a 4.4mm balanced option for headphones that support balanced connections. It also features a 6.3mm jack for headphones with standard single-ended connectors. If you’re using earphones with a 3.5mm plug, a 3.5mm to 6.3mm adapter is available, so there’s no need to worry.

The unit also includes an analogue balanced output on the back panel, ideal for connecting active speakers via a 4.4mm to XLR adapter. As the ZEN CAN Signature is fully balanced and dual-mono circuit design, this is the recommended output option.

No Pain. Just Gain and Bass.

The ZEN CAN Signature offers multiple customisation options to suit a wide range of headphones.
Starting with PowerMatch, the unit provides four gain settings in six dB steps: 0dB, 6dB, 12dB, and 18dB. This feature ensures compatibility from super-sensitive IEMs to power-hungry headphones. We recommend starting at 0dB and then gradually adjusting the switchable gain level to find your optimal volume for both enjoyment and comfort.
It also features two analogue processing modes, XSpace and XBass, designed to enhance the soundstage and low-frequency response of your headphones. XBass tackles a common problem, particularly with open-back headphones: the loss of bass frequencies.

Premium Inside and Out​

The ZEN CAN Signature employs a military-spec PCB to enhance signal integrity. It also incorporates audiophile-grade components, such as:

  • ELNA Silmic II and OS-CON capacitors offer excellent noise reduction capabilities and frequency characteristics.
  • iFi/AMR ‘OV’ ‘Operationsverstärker’ series op-amps provide low noise and distortion, delivering performance that equals or surpasses many high-end headphone amplifiers.
  • For more details, refer to the photo below.
Unlike other headphone amplifiers that come with standard power supplies like those for notebooks, the ZEN CAN Signature includes the iFi iPower2 power supply. This features Active Noise Cancellation II to eliminate all incoming EMI and RFI noise, ensuring a clean and clear audio experience. The iPower2 is already exceptional, being more than 10 times quieter than standard power supplies. For those looking to further enhance their setup, consider the DC iPurifier2, which can further reduce system interference, as well as the iPowerX power supply.


A fully-discrete and balanced amplifier audio circuit. The full symmetric dual-mono headphone amplifier with gold-plated 4.4mm balanced connection. Premium engineering is more expensive but lowers the noise floor to a whisper-quiet levels.
Check out the tech note for the details.

As with many other iFi audio products, we’ve incorporated a custom OV Series operational-amplifier. This top-notch component contributes to the extremely low noise, low distortion (0.0001%) and wide bandwidth.


A Tokyo Cosmos Electric Co. (TOCOS) multi-track potentiometer is used. This has close channel matching tolerance for optimal performance (always use above 11 o’ clock).

Switching between settings has been engineered to ensure sonic transparency with advanced trench technology MOSFET is used as a muting switch.
This FET-based switching is handled by a micro-controller, which only ‘wakes up’ when the user changes a setting, thus eradicating any sonically deleterious interference.

TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.
Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.
They are pricey but are a perfect addition to our products.


Panasonic OS-CON caps totaling 5,410uF give very-low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency response characteristics. In addition, OS-CONs have a long-life span and its ESR changes little even at low temperatures since the electrolyte is solid.
They are not often found in products costing <US$1000.

We use ELNA Japan Silmic II capacitors for the power supplies.
The primary constituent of the newly developed dielectric is silk fibre. This material was believed as unfathomable as an aluminium electrolytic capacitor. The new material beats silk fibre and mixes it with Manila hemp fibre to provide the dielectric to an aluminium electrolytic capacitor used for high-grade music. The result is second-to-none superior acoustic properties and excellent linearity.

Cheers!!

Get It Here!

Is there a good potentiometer replacement I can put on mine which is better quality for better channel matching?
It would make it easier if you told me the specs if that is possible.

Much appreciated.

I do like the Zen Can Sig a lot. Any improvement would be awesome

Thanks for the question,

I can ask this for you and see if I can get any info for you on replacement specs, and post back here.

In the meantime hopefully some folks way smarter than I can give you suggestions!

Cheers!!

Yeah that would be great if there was a volume control pot that was more accurate or an attenuator that would fit.

Yeah that would be great if there was a volume control pot that was more accurate or an attenuator that would fit.

For a number of reasons, mainly size, the volume control is a 9.7mm Type, e.g. Alps RK-097.

Original Specification is Item #R0921G12A1-5-A100K from SINOSTAR (PRC).

http://www.sinostarvr.com/index.php?s=/Show/index/cid/64/id/95.html

So any 9mm size standard 100k Audio Taper Pot will fit electrically and mechanically.

It should be possible to fit this:

https://tech.alpsalpine.com/e/products/detail/RK09712200HA/

https://th.mouser.com/ProductDetail/Alps-Alpine/RK09712200HA?qs=fQ8kcZGzY5UsadoPCXla/A==

Of course this still has a very limited spec of < 3dB Gang Error 0dB ... 40dB range, which on paper is not better than Sinostar.

However, this has a 10K resistance, not 100k and will in the actual circuit used lower gain around 6dB. In addition, it may mess up the Headphone specific EQ, depending how it is implemented

I suggest instead keeping the gain at minimum (0dB or as much as needed to get enough volume), excess gain only adds noise and distortion. That should also keep the volume control away from the range where errors get significant.

Alternatively, make a new case with enough space for an Alps RK-50:

https://th.mouser.com/ProductDetail/Alps-Alpine/RK50112A0004?qs=YMSFtX0bdJBI8HSVYRVKjw==

Upgrade the power supply and fit it inside the same case with a bunch of Oyade connectors and you have a multi k USD Retail HP Amp (and, no, I'm not knocking the idea, the rest of the Zen Can IS GOOD ENOUGH to justify such an approach.

Would a better volume pot make an audible difference ? Or only on very low volume settings?

Thanks Thor !

If you had something genuinely better, yes. Cost may be however very high.

Or only on very low volume settings?

At the levels of that at least on my own Zen Can I consider this a cosmetic problem that is not relevant in real use. Simply lower gain if you are not at minimum.

I love the buttery smooth volume knob on iFi ZEN products :L3000:

Channel imbalance if any, is at the very beginning of the scale. With the correct gain setting, this is never an issue.
