The one and only official Cayin website is cayin.cn. Cayin.com is NOT an official website of Cayin Audio. It is hosted by a Cayin dealer based in Germany. He is one of Cayin's earliest overseas dealers, and they registered Cayin.com long before Cayin developed an Internet presence. Since I...

If this is a brand new unit and you used it for only one day, I guess that's less than 10 hours of running. Your 170HA is still in the early burn-in stage; both the vacuum tube and output transformers will need a longer time to settle down before you can form an opinion of the sound signature of...

When I wrote the disclaimer on user manuals, I had to consider the latest legal practise, the scope of liability, and versatile user conditions over a much wider global market. :smile: The user landscape is also very different when compared to the good old days. Back in the 90s, expensive...

The cramping force of the outer case was designed to reinforce the structure of the HA-1A, keeping it straight and upright when installed. The HA-1A is not particularly heavy by transformer coupled tube amplifier standard, but it is insanely dense consider it's small footprint. Hypothetically...

From the photo you provided, I believe you are using tinySA Ultra ZS405 I think this is helpful to other tube amplifier users, I'll pin this post to the HA-2A FAQ because I have compiled a fairly complete reference collection there.

I have encountered similar requests at shows and meets, from what I experience, the result of similar tests might vary because of IEM used; Noise floor of the environment; your sensitivity to high frequency noise; and how skillful you are in "looking for" the noise. On the other hand, this is...

I am not knowledgeable in Stax energizer, but a quick Google search mentioned the "recommended amp output range is 10-30 W", which means HA-300 or HA-300MK2 is marginally below the recommended range. You can give it a try if you have the energizer, it shouldn't cause any damage other than...

Ah.... so we have to deal with 3 volume control here: Roon core digital volume, Linn Klimax analog volume and Soul 170HA analog volume? And you want to use the system for both headphones (Susvara OG) and speaker (Borresen X1s) applications. I don't think you'll find a "formula" for a...

When you use a pre-amp output, feeding it into an integrated amplifier (such as the Soul 170HA), you have TWO voltage gain stages and TWO volume controls in your system. Assuming we have two preamplifiers, one with a max rated output level at 20V, and the other at 6V, the volume position of the...

When you have double volume control in your system, you need to determine the sweet spot for your system specifically, there is no 100% correct formula here, it depends on the volume control and pre-amp output stage of your high-end DAC/Streamer/pre. Saying you are using a piece of high-end...

I am just curious, can you provide some information regarding your DAC? Most standalone DACs will provide Toslink and Coaxial inputs because these are very common SPDIF digital inputs nowadays. That's why N6iii is equipped with one of these output formats but not both.

If the DAP Audio Ground and charged Ground are shared ground, it is shared whether you power on or off the DAP or amplifier. (HERE) We have tested the C9 protection mechanism repeatedly, it will disconnect the C9 from the circuit promptly and won't cause any damage to the DAP. On the other...

Since I communicated on behalf of Cayin in this review arrangement and @Gold Fox didn't have access to our email exchanges, maybe I can provide a better explanation. I can't disclose our communication with Convince Me Audio for courtesy reasons, but I can repeat my explanation here for your...

We have sent a set of HA-2A with iDAC-8 to Convince Me Audio, Koji received the review samples on 3 July 2024, and he included a brief preview of HA-1A and iDAC-8 in one of his Susvara Unviel videos 4 months ago. The HA-2A review is now online, we are still looking forward to the iDAC-8 review...

Cayin hasn't had any desktop R2R DACs so far. When I was the brand rep of Cayin, I always advised my users to go for what was currently available instead of waiting for something that didn't have a firm deadline (or ETA). I am a firm believer that if you like our house sound and corporate...
