Sorry for the late response on PM, I am on leave in the UK. First of all, to get out of the protection mode, you need to disconnect all cables from the C9, then connect the C9 to any USB charger and start charging, the amplifier will resume operation within one minute. If you want to use your...

I suggest you get in touch with your dealer regarding your problem, take a short video showing the LED indicator is not responding, and send it to your dealer, let them confirm whether you controlled the amplifier correctly and it's a hardware problem that you have encountered.

If you don't need the portability of an ultrabook, a desktop PC will outperform the ultrabook as well. I was the first to suggest, in the C9 thread that, if you don't need the portability of the C9, a decent desktop amplifier at a similar price range should outperform the C9 hands down. I...

All 5 stock vacuum tubes in HA-2A are NOS vintage tubes, this is our first attempt to develop a tube amplifier with NOS vintage tubes. This is a very inefficient approach because we need to estimate the total production number in the complete product life-cycle, and stock all the vintage tubes...

Drop by Spirit Torino booth at CanJam London, the Centauri is a present surprise, very portable friendly, effortless with decent headroom at Modern Tube, High Gain Vol 60, I didn't know the price during the audition, but I was surprised by the overall performance with N3Ultra. I assume the...

My train just passed Milton Keynes, there is some delays as usual, hopefully I'll arrive around 11am. This is my first Canjam since the COVID outbreak, I am very excited and is looking forward to seeing friends and colleagues again in the show.

I wish I could, but the Tungsten is unavailable in Hong Kong and China, let's hope someone will bring a pair of Tungsten to one of the CanJam and check it out with Cayin's headphone amplifiers in our booth. The CanJam London is around the corner and we have the iHA-8 demo at Hifonix booth...

The XLR-4 headphone output is rated from 15 watt per channel to 18 watt per channel, depends on the impedance matched setting. Therefore the a170HA can indeed deliver 18wpc to your headphones. But rated output is only part of the story, the driving capability is largely related to current...

We have completed the first small-scale production run and will deliver the amplifier to our local (China) dealers soon. Most of these units will be shop demo units in specialist HiFi stores. We have measured the first batch of mass-produced 170HA and noticed that the measurement is different...

If you buy from our official store in Aliexpress, your DAP will come with a warranty, but I am not familiar with the detail terms and conditions of AliExpress transactions. Please drop an email to john@cayin.cn, he should be able to provide detail information regarding warranty coverage on...

In terms of audio performance, you don't lose anything, in fact, pre-amp input mode allows the C9 to work at f ull power, you are hearing the full potential of the amplifier, so you don't need to worry about that. If we need to pick the bone, then we can argue that we are using a relativeily...

IF this happened suddenly, then it doesn't sound like a software problem, please drop an email to service@cayin.cn, and they'll go through some questions to debug the problem, if your DAP needs repair, you can either go through your local Cayin dealer or work with our service team to get this...

Headfonics has published a detailed N3 Ultra review today. Marcus must have enjoyed his time with N3Ultra because he rated the Sound Quality of the player as 9 out of 10, and Synergy as 9.2 out of 10 and considered the Cayin N3Ultra DAP "a huge step up" from the older N3Pro. You can check out...

Sorry to disappoint you, but we didn't include the custom FIR filter feature in our N8ii project, other users had raised this question previously and I had explained our position on this subject. Besides, when we declared the EOL of a product, it was unlikely that we would develop new...

I believe the Oppo 205 was developed before the streaming norm, so it was designed around the concept of a local music library rather than online streaming. They have provided the necessary support to connect the Blu-ray player to your local NAS server and that's all we can expect for something...

To make it easier for everyone, I have pinned the message at the bottom of the opening post, right below the offical compatible tube table. :beerchug:

Factory reset won't scan your microSD card nor change the content on the card, so you are safe to perform Factory reset without taking the card out. It will 4remove the music file database so you need to rescan your microSD card and build the Music Library again.

Thanks, I stand corrected. :beerchug:

If you can make it go away but it will recur sooner or later, sounds like a hardware-related problem to me. Please contact your dealer and report your instance in detail, they should provide the necessary support to handle your problem. Unfortunately, I can't help if this is a hardware...

This remains a WIP with an initial schedule for 2025, the circuit design is moving on satisfactory but we are battling to improve the industrial design, the structure and control mechanism of the retractile tubes are very difficult to mass produce, so I won't expect any official update within...

I shall repeat my final sentence in my previous response: If we make our Dongle DAC/DAP connector more friendly with Pentaconn 4.4mm connectors, many aftermarket 4.4mm cables will find it a bit too loose to feel comfortable. Sorry for not trying to cover things up or deploy a delay tactic that...
