Cayin N7: A Voyager of Unexplored Frontier
Cayin didn't change the sound signature of our DAP through firmware, not with the recent N7 firmware update, not with any N7 firmware update, and in fact, not with any DAP firmware update we have maintained this policy since we launch our first DAP N6, we have received numerous requests to...- Andykong

Cayin N3Ultra: an Entry-level Portable DAP that Delivers a Complete Vacuum Tube Audio Experience
You are always welcome and you can ask again anytime. Unfortunately, this is not within my scope or jurisdiction. If the software team requires additional information, I'll try my best to explain and put the request into context, but there is much I can do other than that.- Andykong

Cayin N3Ultra: an Entry-level Portable DAP that Delivers a Complete Vacuum Tube Audio Experience
No comment, I have forwarded the request to our engineer. The software team will evaluate the information I collected, I am not part of the decision-making process. I have no idea whether this is technically feasible, or the resources required to implement the feature.- Andykong

Cayin N3Ultra: an Entry-level Portable DAP that Delivers a Complete Vacuum Tube Audio Experience
I assume you'll connect the WP900 with the 4.4mm or 3.5mm headphone outputs of N3Ultra, in that case, the numbers you quoted are not relevant, these are the rated output level of LINE OUT, not phone output. From what you have described, I believe you are concerned about the appropriate GAIN...- Andykong

Cayin C9: Dual Nutube, Fully Balanced Class A/AB Portable HeadAmp
Indeed, that's why I started with the qualifying statement that we "designed C9 as a battery power amplifier device", this is a very important criterion that we must clarify before we discuss the pros and cons of the product. With this in mind, this is a feature, not a b bug. :beerchug...- Andykong

Cayin N3Ultra: an Entry-level Portable DAP that Delivers a Complete Vacuum Tube Audio Experience
Unfortunately, the JAN6418 is not user replaceable, you need to send the DAP back to your dealer or to us (China) to replace the vacuum tubes. For the record, we do run into JAN6418 occasionally, but most of them happened on the first month of ownership, a small number of them in the first...- Andykong

Cayin C9: Dual Nutube, Fully Balanced Class A/AB Portable HeadAmp
Absolutely NOT. If you are looking for a small headphone amplifier that can be hooked to a wall AC outlet and operates as a desktop amplifier, C9 is not a good choice. There isn't any external power supply that can support C9 directly without the batteries. When you connect the charger and...- Andykong

Cayin HA-2A, Compact Tube Headphone Amplifier
Saw the 8-series stack right besides the HA-2A, so I guess you have dropped by our Munich high-end booth and have checked out new products as well. I hope you are impressed by the new products as well. I assume there is a set of HA-3A somewhere in the booth, or it wasn't hooked up but in...- Andykong

Cayin HA-300MK2 (2022) TOTL Transformer coupled Direct Heated Triode Tube HeadAmp (Page 91)
If that's the actual signal flow, the headphone output will also bypass the potentiometer. The flows with three arrowheads are signal control circuit. To follow the audio signal, follow the regular single arrowhead path.- Andykong

Cayin HA-300MK2 (2022) TOTL Transformer coupled Direct Heated Triode Tube HeadAmp (Page 91)
While I can think of several possibilities to explain or test regarding your distortion problem after you crank up the volume to 3 pm, none of them can explain why it was OK in the past and the distortion shows up suddenly, especially when you have assured that nothing has changed in between...- Andykong
