I spend about 3 hours in Yulong's Shenzhen workshop, audition all three new products, and a quick factory tour in Yulong facilities. The D200 is indeed an amazing all-in-one unit, I simply cannot resist the temptation and bought one home. This is probably the first unit arrive at customer hand even in Mainland China.
Lets look at some photo first, I'll add impression to Yulong D200 gradually - I'll be away immediately after the Easter holiday for 1 week, so I probably won't have time to listen to the D200 until I comeback from my business trip.
Yulong pack this one up for me in person, he is definitely a hands on guy from the ground up.
Double Box packing, good for serious traveling
The actual packing box is quite tough, reinforced at both sides, so you should receive the D200 in good shape
The Box is really plain, just a serial number label on the side, with Yulong's autograph label.
Open up, well protected by foam.
Finally something interesting, ....
Nothing fancy, just the D200, a USB cable and a power cord. Yulong said the User Guide is still in printing, I'll receive that later.
Although this looks "standard" to me, but I'll keep this in the D200 packing just in case, as some DA8 users reported that not all USB cables works well with Yulong DAC.
Finally I get my hands on the D200, exciting moment.
The D200 is identical in width to DA8 and A28, but with black chassis instead of silver, which mean you can stack it up with A28 and still looks good.
The workmanship is actually better then most Mainland China gears that I have owned or tried out previously (which is quite a lot consider I am in Hong Kong), and at RMB3380 (!US$543), I think this is a steal.
The control is simple, a 6.3mm headphone jack with 80 steps volume is the bread and butter of D200 front panel. The Input button will toggle through the Coaxial, Optical, AES and USB in sequence. There are supposed to have four digital filters build in but I need the manual to explore that. There is also a jitter on/off which will help to deal with lower quality digital filter (when on).
You have all the Digital input you needed. I probably will stick with Coaxial for a while, but I have very high expectation on the USB input as Yulong has spend a lot of time to refine that part.
The D200 has a pair of RCA for single end output, and a pair of XLR for balanced output. Yulong is a firm believer in Balance audio design, so I'll advice you to use the Balance out whenever you can.
D200 has build in pre-amp function, you can use this analogue connector to line up with active speakers, or a power amp or a headphone amp., or if you want to use it as a dedicated DAC, you can a actually turn off the headphone amp and preamp function by long-press the volume button and the unit will become DAC.with fixed level output.
One of the unique feature of D200 (and DA8) is that you can use the XLR analogue output to pair with balanced headphones. You probably need to build a adapter cable for that purpose, Yulong has provided some instruction at the following link:
(will translate the pin-out for English reader later)
Not all DAC will work with balanced headphone in this manner, Yulong has purposely design the DA8/D200 with this in mind, if you read the spec. carefully, you can find the following lines:
●Balanced pre-amplifier output with buffer, which can be used as balanced headphone amplifier
Technical Specifications :
Full Balanced Output level:4.2V
This is my headphone lineup:
Yulong has given me an adapter cable on the spot after audition, I shall use this with my Alpha Dog in the future
I'll test the single end headphone out with my HD700, Sony Z1000 and various IEMs.
And finally the RCA output from the D200 will be the source to my Koss ESP950.
I'll write up more on the detail of the Yulong visit next visit, mainly on comparing the D200 with DA8 and A28, Yulong has kindly provided three headphones (HD650, HD800 and balanced modded T1) during my audition, I hope this will be a fun impression for D200 when I completed.
