Vintage Military Miniature Tube
Dual RAYTHEON JAN6418
A low power consumption, only slightly warm pentode tube can be integrated for Triode or Ultra-linear mode.
It was originally used in military communication applications and installed in high-end condenser microphones because of its "warm classic tube sound”.
Microphonic and Shock Treatment
To minimize vibration of the filament, the tubes are housed in a custom made silicon case which is suspended in a specially crafted slot. By using a flexible PCB we maximized this suspension effect.
After months of trials and many redesigns, you can now walk around or place the player in a backpack while listening with nominal detrimental effects.
Microphonic effect might be audible when jogging, knocking on DAP, holding the DAP and then place it on table or knocking on table when DAP is placed on it.
Features two AKM AK4493EQ DAC chipsets, natively decodes up to DSD256 and 32 Bit / 384kHz with stellar dynamic range and resolution.
When operating in Mono mode, the DAC will deliver better dynamic range, signal to noise ratio and channel separation.
Fully Balanced Design
Powerful 800mW Headphone output
The DAC outputs the hot and cold signal streams identically except for the polarity. These will go through LPF and a headphone amplifier in parallel.
When L+, L-, R+ and R-are transmitted and processed independently, common-mode noise will be cancelled out and cross-talk will be reduced.
The differential headphone amplifier outputs the difference between the hot and cold signals, and this will increase the output power and channel separation significantly.

Cayin - N3Pro Portable Balanced Audio Player with Vacuum Tube (+Free Green Case Bundle)
I was mainly looking for a DAP with a dedicated player OS, i.e. non-android. I had DAPs of both Android (iBasso DX220, Fiio M15) and proprietary OS (Sony WalkMan). The N3Pro is simple to use, fast to boot, and supports most audio formats. Since most reviews already discussed its greatness, I'll just list the minor problems I found. First, compressed SACD ISOs are not supported. Because it's not obvious whether an SACD ISO is compressed, I had to copy it into the player and see if it plays. If not, it needed to be converted. Second, the 3.5mm line-out and phone jacks are next to each other. An inexperienced user may plug into the wrong one. I used a rubber plug to cover one that's less used. Third, I did try the tube output to drive a pair of electrostatic headphones with a transformer. The output was very underpowered and I could barely hear anything. Finally, the OS froze the first time I scanned the music.
Very good for the price. I I’ve been a fan of tube amplifiers for many years .
I am very pleased with the overall performance of the Cayin N3Pro, its easy portability, and its excellent sound quality when used with a variety of headphones. A major problem is that its advertised connectivity doesn’t work. When I received my N3Pro, I upgraded the firmware to the most recent available as of mid-April 2021, 2.1. My iPhone is an Xs running IOS 14.4.2. It is advertised that the N3Pro can be connected to and controlled wirelessly via Bluetooth by an iPhone app. I tried diligently to use the app to connect my iPhone to the N3Pro. It simply does not work. It is also advertised that the N3Pro, in DAC mode, will connect to an iPhone via the USB connector on the iPhone camera adapter. I used Apple’s camera adapter that also has a charging port, connecting the charging port to an outboard power supply. A camera adapter without the charging port forces the iPhone to charge the N3Pro, and the current draw is too great for the iPhone. I have been unable to set up a stable connection between with my iPhone and the N3Pro. The N3Pro is the only DAC device I own that cannot be connected quickly and easily to an iPhone via a camera connector. Overall, I give the N3Pro high marks for build quality, sound quality, and overall performance as a stand-alone portable music player. I wish that I could say the same thing about its connectivity to my iPhone. Its utility is held back dramatically by its lack of easy connectivity.
I've just received and started using my new DAP and have enjoyed my experience so far. The DAP is solidly built, very user friendly and focused, easily loaded my 6,000 songs once I inserted a micro SD card and the sound is fantastic coming through the tubes. I look forward to using it more over the coming weeks and months.
I was using a Sony WM1A for my DAP and it’s small, has huge battery time and plays hi-def, but I was looking for something with better sound. I wanted to step up to the $1K plus offerings, but I saw this at half the price and went with it because of the novelty of the tubes. I don’t care about anything but sound. I don’t stream. So far, so good. It’s got great sound and has so many variations. Seems like a great bargain. I’d love to her the Astell& Kern or Sony expensive DAPs, but for now, I’m happy with this.
