The N6 has been Cayin’s flagship DAP since 18th December 2014, quite a long duration in current DAP market. Cayin has been planning for a new flagship for quite some time but the progress is very slow. One of the requirements of the new flagship DAP is to bring the audio performance our DAP to the next level, and to do that, we have used the N6 as a platform to explore all sorts of possibilities.
The project N6 mod was started way back in Q3 of 2016, it was an internal R&D project commissioned to the original N6 Design Engineer, it is a cost-no-object study to “improve” the audio performance of N6. After several months of devoted testing and experiments, the final N6mod incorporated quite a lot of dramatic changes and Cayin believes we have established the baes line for the audio performance of our next flagship. We anticipated that the new flagship will exceed this base line significantly given we can incorporated these new audio design technique and have the flexibility to adopt better chipset and components that is not possible in the N6mod project.
The followings are some of the changes (the exhaustive list will be too technical and lengthy):
- Lower the Internal resistance by replacing a large number of capacitors to premium components, improves the high frequency extension and transparency.
- Upgrade the transistors in RC Network and feedback circuit, re-calibrate the parameters of power supply circuit for LPF and amplification, improves frequency respond to 18Hz~42K Hz (±0.1dB);
- Upgraded Op-Amp (OPA627)
- Upgrade to customized military grade Crystal Oscillator
- Reinforced power management and fine tune impedance, voltage, and/or bias current of key components.
- Redesign power supply circuit to all high-voltage Op-Amps.
We only make 10 units of N6mod, 5 of them were built for the
special event of 15th Anniversary of erji.net (the largest HeadFi forum in China), and the other 5 were used for internal testing and audition only. Since Cayin has no intention to sell any of these, so the N6mod are non-commercial items.
I will attend the Los Angeles Audio Show (2-4 June 2017) and I’ll carry a N6mod with me, if you happen to attend the LAAS later this week, drop by and check out the N6mod, I am confident you’ll like what you hear.
