Twister6 has a review of the Cayin N6ii digital audio player over on Head-Fi. The cool trick with this DAP is that it has replaceable DAC/AMP circuitry. The circuitry is on a motherboard (they should be calling it a daughterboard) which is removable from the top of the player. The remaining components such as the motherboard and battery are all static and are fixed in the case. This actually reminds me of my old HP 41c calculator of days long past. This is an intriguing concept and I will be interested in seeing where it leads.
Twister6 posted on Head-Fi his review of the N8 DAP. From the unboxing photos it appears to be a very attractive digital audio player and has a plethora of cable types include. I will leave the details for you to read in the review but the fact that you have the choice of vacuum tube and solid state amplification in 3.5mm headphone output is intriguing. The one downside is that if my math is correct the cost in US Dollars is over $3,300.
Pros – Solid State and Vacuum Tube (Korg NuTube) amp outputs, High Output mode, solid stainless-steel build, responsive interface, plenty of digital and analog outputs, selection of custom cable adapters, duplex LDAC Bluetooth support.
Cons – price, weight, touchy up/down dial, 5sec tube warm up delay (more of annoyance than Con).
Twister6 posted a review of the Cyin N3 digital audio player on Head-Fi. From the review it sounds like a great DAP and for just under $150 the price is right. Also, it directly supports ISO and it BT capable.

Nmatheis posted a review of the Cayin N5 Head-Fi and calls it the lovechild of Cayin’s C5 & N6. Overall it sounds like th Cayin N5 is comperable to its competition in its market space of ~$350.
