I've had 2 issues with my D100. The D100 will lose the signal from my PC once in awhile. I think this may have something to do with plugging/unplugging headphones from my ext amp. Regardless, the display reads "NoSignal" and the computer no longer sees the device. I have to turn off the unit then turn it back on to get a signal again. This has happened on both my Mac and PC. The second issue I've had is when I have the unit on and working for extended hours (more than 8 hours or so such as when I leave it on to listen as I go to sleep). The sound curiously starts cutting out and sometimes I lose the connection between my computer and the D100. I will then turn off the unit and let it cool down. After that, it works fine again. I'd hate to have to deal with a Chinese company for warranty repairs especially with the shipping hassles at my expense and no guarantee they could actually fix it the first time. I figure, as long as these are the only problems I have with my unit, I'll just hang onto it and throw it out if I ever upgrade.

I think what I'm going to do is buy the Yulong D100 and if I ever get something such as orthodynamics I'll get a powerful amp. I'll use the D100 for dynamics and that be enough for me. 
 
I'll buy these when tax season is over so I'll actually be at home so mid to late April should be when I get these.

Yep, this is the same issue I was talking about. Except for me it happens with plugging/unplugging things in/out of either the HP or line out...but not consistently it seems.

don't have the prolonged listening one, but I never use my unit for more than 2 hours. Although it does get quite hot where I live (30-40 deg C)

p.s wrt to grados and d100 - I tried a loaner pair of HF-2 from Stang with my D100 a while back, and it was the most caustic treble I've heard. UN-listenable.

Anymore opinions? What's the consensus?  Bright or Neutral?  Anyone use it with Grados?
 

I think that the D100 amp has an energetic and revealing treble, but nonetheless I find it above all neutral and transparent instead of bright.
With my stock GMP 450 Pro, I'm definitely getting a bright sound but it's more the headphone fault since it's an already bright sounding one. (which doesn't really bother me because it's tonal balance is very easily tunable via different earpads)
I believe that the Yulong D100 might make for a bright and thin sound when paired with more difficult to drive headphones because it might be driving those headphones with suboptimal amplification and not necessarily because the amp has a bright character.
In a way, I think that's hapening with my GMP 450 Pro (2*300Ohms).
With my easier to drive and very transparent Head Direct RE0 IEM, which has a bright and thin character, I don't find the Yulong D100 amp to make the sound brighter nor thinner nor darker nor thicker than the IEM own character.
The same with my other IEMs.

And my D100 doesn't have none of the starnge issues that are being reported.
Just channel imbalance at low volumes with my IEMs...
Haven´t used the line out yet, though...

is it better to get the yulong d100 from ebay or from audiophilechina.com
 
it seems it's cheaper from audiophilechina but no one seems to mention them.
 
thanks

I use Grado RS-1s (not the i version) and find the D100 neutral & very revealing.  That being said, bright recordings will be very evident using RS-1s.  However, unlike most on this thread, I find that Soundmode 2 takes the edge off of sibilant recordings quite nicely without sacrificing significant detail. 
 
That being said, I still prefer using my MAD Ear+ as my primary amp (with most recordings) with the D100 as the source.  The internal D100 amp is solid though and should please you for a good long time until you decide to upgrade.

Thanks.  I'm planning to order.

Mine came! Unfortunately it uses a european plug so I can't use it till I go out and buy an adapter. Didn't think of that when I bought it off reiserFS! Toslink to Mini cable in the post too. Patience....

Cheaper but... make a search with "audiophilechina" on this forum and you'll see by yourself...
 
If no one mention it perhaps there are good reasons...

 

[reiserFS]

Mine came from Audiophilechina and I couldn't really complain about them besides they writing 50$ on the customs value declaration.

Question. Rather than buying an adapter for the plug I'd rather just get a new power cable since I could do with the supplied one being a bit longer, regardless of the pin-type. What's the technical name for the cable type? I'm having a brain-fart moment!
 
EDIT - it's a 'kettle' lead isn't it? 
EDIT 2 - 'plug to IEC cable' is the technical term!

I got mine from Audiophilechinea.com and have no reason to complain...
1 week after payment, the packge arrived at my home and had no issue with customs.
 

 

[Somnambulist]

To answer my own question, found this earlier in the thread: http://www.head-fi.org/forum/thread/499562/review-yulong-d100-dac-amp-reference-quality-with-a-reasonable-price/285#post_7189228
 
Just ordered a standard 1.8m power lead from OCUK, so that's me sorted.

JTam,
 
Does the Chinese New Year affect your shipping?
Is it correct that DHL will not be in service until Feb. 11?
 
thanks

same. took 4 days.


to the guy who's going to get an adapter instead of a new IEC cable for the same price - get a new IEC cable. They're sold at _ANY_ computer store edit: o, ops, you already have. k
