User questions & answers

Question:	When will these be available to purchase
Answer:	It’s available now
Question:	Can it run while charging
Answer:	Yes.
Question:	Hi it’s supports iPod and iPad? thank you
Answer:	For iPad Pros and the latest ipadOS, you can just directly use the usb-c to usb-a that comes with this dac. For iPhones and iPods you do need the camera connection kit. I am using it with my iPad pro 2018 with the included usb-c cable
Question:	can this be used for my car stereo
Answer:	I strongly advise against doing so. I'm assuming your question is "can I plug this into the auxiliary input on my car?" In which case, no. Doing so would be "amping and amp" and that's a no-no in electronics. You run a really high risk of burning up both things when connected in this way. The Hip-Dac is one of the few products in this product category that does not provide a line out or a pre-out. It also does not do bluetooth. Typically I find that a phone's or mp3 player's headphone output is sufficient to plug directly into a car stereo. The road is not a great place for hearing that last 10-20% of fidelity these products provide. However, if you still need the option, the Topping NX4-DSD and the Fiio Q1 mkII are similar products that offer a line-out that you can use to plug into your car stereo.

User questions & answers

Question:	Can I plug in a set of phones to the device and walk around connected it to a source wirelessly

User questions & answers

Question:	Does this work with the samsung galaxy note 20 ultra, note 10+ and any previous note like the 8 and
Answer:	It works with my Galaxy s20 (6.2 inch). I use the USB audio player Pro app
Question:	Does it do MQA
Answer:	No, the Hi-mDAC does not decode MQA. If you're using Tidal, the software player can do the first unfold which will send PCM 88.2k or 96k to the Hi-mDAC.
Question:	What end of the usb cable is to conect to the nuprime devise? Usb c or usb a
Answer:	The connector on Hi-mDAC is USB-C. A USB-A to USB-C cable is included. If you are using Android phone, we suggest that you buy a USB OTG converter. Please refer to NuPrime website product page for information about using Hi-mDAC with Android or iOS devices.
Question:	Will this work with ipad pro via usb c to usb c cable
Answer:	Not directly like this. This is due to Apple's design that all USB audio has to go through the "Camera Adapter Kit. What that adapter does is to allow external DAC or storage device to appear as a USB client device to iPad. Mobile devices (iPad, iPhone) are themselves USB audio client devices designed to be connected to a computer. Therefore two client devices can't talk to each other until the adapter changes how they communicate (master to client).
Question:	How do i connect this to my android phone (note 9)? what else do i need to purchase
Answer:	You can use a 2-in-1 OTG Converter (available as Amazon's Choice for $6.90 to connect between your Android phone cable and Hi-mDAC, or buy a USB-C to micro USB OTG cable. I think a OTG converter is the most convenient to work with existing cable.

Notice:

When using B4-X with your cellphone, if you heard some "zhi ~ zhi" noise in your headphone. Probably it is the inteference from your cellphone such like WIFI or 4G signal, which intefers the tube and cause noise. That's normal. Because there are microphone effect with all tubes. To avoid it, please keep your cellphone far away from B4-X.



Q&A:

Q: Tried different source and headphones, but the right channel still has static.

A: Maybe the tube has a poor contact after long shipping process, open the chasis and adjust the screw near the tube while listening (if you cannot find it, contact us and we will give you a photo with marks to help you). Maybe the tube is broken, you can buy a 5899 tube in local shops. And we will refund you the cost.

Q: It broke just now four loud pops and it's doesn't work now.

A: Mainly because the battery is run out of power. Please charge it. If no help, please contact us.

Q: The Amp has a lot of electronic feedback/interference when a cellphone is nearby. It creates popping in the headphones.

A: Vacuum tubes are easy to be interfered by devices that can transfer siganl like cellphones, routers. Please keep the amp away from them.

Q: It cannot be charged, something is loose inside the charger.

A: Maybe the charger is broken. Contact us to get a new one please.

• The difference between B4 and B4-X: ① B4-X is a dual-mono balanced version. Its left and right channel are amplified by independent components, and power supply, tubes, and op amp are all independent and symmetric. So the degree of sound separation is higher than B4.
• ② B4-X adopts 2 groups of independent power supply(+12V and -12V) for 2 op amps, less mutual effects and can drive 300Ω headphones. ③ The circuit adopts dual op amp parallel output, with higher output power. ④ B4-X has 3.5mm and 2.5mm 2 kinds of output interface, suitable for most of balanced and standard headphones.
• Mini size and unique design: built-in tube makes you have a tube amplifier which can be held by one hand, convenient to carry and can enjoy HiFi music everywhere. Full, delicate and soft sound: warmer than transistors, independent op amp and power supply inhance the SNR and degree of separation, less interplay and higher sound quality.
• With built-in battery protection circuit: battery lets your listening feast without time limitation. It can't be turned on during charging and will power off automatically after fully charged, and charger LED will turn to green.
• High-end making material and craft: using gold-plated socket, original nichicon electrolytic capacitor, original DALE resistors and precision ring resistance. Prompt and courteous customer service.

User questions & answers

Question:	Why does mine not work?.after charging it,the tube doesnt light up and no sound
Answer:	Make sure all the connection from the wall to the unit is properly connected and secured.
Question:	Is it okay to stick a piece of paper over the circuit board? The yellow is an eyesore
Answer:	The "yellow" color is the copper circuits themselves, which is the main selling point of the product. If you don't want to see the retro design of circuits or tubes, buy a different product.
Question:	Anyone compare the sound quality of the little bear with a more expensive or non portable tube amp? Thoughts
Answer:	I have the Valhalla 2, but it doesnt have the traditional "tube sound". However, what I can say, I have the DT990 and I hate the way it sounds from the Valahalla 2. This amp though, tames it in such a pleasing way. Now, along with those, I use the HD600 primarily for listening. The Valhalla 2 has amazing synergy with them. It tightens it up and make them sound amazing. For portability, I have tried the HD600 with this one as well. It sounds a bit more laid back and closer to what youd expect from tubes with PLENTY of volume. TL;DR: For the price, this little amp is pretty great.
Question:	Can it play audeze lcd2c and dt
Answer:	Don't know, but it does well with dt 990.
