Cayin N6ii Replaceable Audio Motherboard R01
Did run my N6ii first with A01 and then E01 which impressed me a lot. Now, after all the very positive feedbacks I decided to go for the R01 and initial impession is outstanding, very reference like. Still burning in and enyoing it very much.
In that I currently own 4 Cayin Nii6 Master DAP boards (A01, E01, E02 and R01) and the Cayin C-9 Amp, I have to say the R01 ~w the ladder DAC Tech has a beautiful natural almost liquid sound .. definitely consider this board as part of your Nii6 collection, if able.
To add, Andrew and MusicTeck are top notch, 1st class to deal with pre-purchase through to post purchase!
Very smooth, organic sounding yet detailed. I have all the modules and this one is perhaps my favorite.
out of the box, this is a HUGE step up in terms of overall sound quality (that suits my preference) from the stock amp of my n6ii.
I promised to write a follow up to my previous review after receiving the arctic cable Magnus. Now both the cable and the R01 are properly broken-in.
1st. Remember to update the Cayin N6 II to optimize it for the Passive R01 circuit and features
2nd If using Headphones with Efficiency in the 93db or lower, change the Cayin gain to Hdb(high gain), with the E02 active circuit there is more gain and "for me" I found that going Hdb I could detect some slight distortion and to be linear I had to stay at Mdb (medium gain), but with the Passive R01 I needed the higher gain for my Arya Headphones at 90db efficiency and it didn't distort at all, it remained linear, just pure clean Sound.
3rd I always turn off the WiFi and ofcourse the blue tooth, I notice that these added some coloration which I dont like (its not very noticeable, but I like purity), if you stream then you cannot do that. I listen to HiRes Files mostly from my memory stick.
I cannot describe how much better the sound was, more detail, greater harmonic content can be heard around each instrument.
The Arctic Cable very high quality and low impedance allowed the amp to drive the headphones just a bit better like gaining an additional db or so! The sounds just bounce nicely and naturally out of the headphones just so so rich and resolved.. check out Francisco Col's Turia (Guitar concerto) on the alpha label, truly beautiful music very well performed and superbly recorded...the organic lifelike nature with which each instrument project out in glorious detail and richness is stunning..... enjoy
