    Hello Head-Fi!

    @Andykong of Cayin asked your dear old Pinky if I'd like to be a beta tester for their new music player, the N5ii. Naturally, I said yes. I love Cayin products... a lot. So, when I get my hands on the unit, I will share some of that experience with you, here in this thread.

    This is also the best place for your general conversations about the N5ii. Impressions and reviews ought to be found here as well... when it hits the market.

    In the meanwhile, enjoy some sweet, sweet info:

    Are the released specs final?

    Considering the N5ii is set for release in early December, it's safe to say these specs are as final as they ever will be. They are gathering supplies and building them as we speak. :wink:

    Nice! Can't wait...

    I am curious why so many of these DAPS choose the rockchip 3188 processor, as they are pretty slow.

    Also releasing a DAP with the 9018 in December, seems a tad out of date. 64GB internal memory and at least 2GB ram would have been a a nice addition to separate this device from current DAP offerings.

    The software development and audio implementation sure better be fantastic with these reported specs

    Yes, Google play pre-installed, and you can install Spotify app to N5ii if you have a Spotify account.

    Like it or not, getting a decent MCU is one of the most challenging part of developing a modern DAP. There are two problems here, the obvious one is supply chain issue, a HiFi brand will need around 10K units of MCU to support one audiophile grade DAP products, a mobile phone brand will go for around 500K units for a regular mobile phone products, and will go well beyond 1000K unit with popular models. The reality is, without an established relationship with the semiconductors big-names, even getting a supply contract on outdated MCU is far more difficult that consumers can imagine.

    The reason that semiconductor feels reluctant to work with small scale projects like DAP is because of the commitment of solution provider, and this is the second problem that stop us from using a modern MCU in DAP. The MCU is useless until there is a "solution provider" willing to take up the project and develop a "solution" for a particular application. You can imagine DAP is a niche market that is not particular attractive to the solution providers.

    We expect the 1G RM + 32G internal memory will continue be the norm of sub-$400 Android DAP. The current N5ii can support upto 544GB (32+256+256) storage. Adding another 32GB to this will increase the maximum music storage by around 6% only, nothing really significant. N5ii uses eMMC as internal memory, its more expensive then TF cards in general, so we think it is more cost effective by keeping the cost of DAP down with 32G internal memory only and let users allocate the budget to the TF cards flexibly. At the end of the day, nothing comes free, its just a matter of paying for the eMMC internal memory upfront, or to get a bigger TF card when you really need the extra "few" GB.

    Is the sample rate conversion in android bypassed?

    Thank you Andy for giving us a rare and candid glimpse into the making of a (good) DAP. Too often we, as users, tend to think of the DAP market as such a big market, wheres, as you point out, it's just a niche market, and not the biggest one either. My son is a sound engineer, and a (would be) music producer, so we have discussions on equipment and users from time to time. His impression is that the "mobile audiophile" market as a whole is a not that big, and is generally not understood or cared about by the younger generations, as they tend to have different spending priorities and are happy to enjoy their music with cheaper, less performing equipment. What might be done, and I think it has already started, is to expose the young users to better sounding mobile equipment, DAPs, headphones, iems, so that when they get a taste of a much better music experience it will be more difficult to go back to less performing gear. This one of the ways, imo, this market can experience increased growth. Sorry for the digression!

    Hi Andy.
    I use i5 DAP, and loving the sound.
    I have one question, does N5ii support aptX HD?
