The master has spoken. Glad I've bought a unit, currently in customs but should arrive soon at my place.

My review pales in comparison to Project86's. But I basically agree with most of his findings. I did an additional comparison to the Music Hall DAC 25.2, but otherwise couldn't cover much new ground.

Project86, you did not mention the "Sound Mode" buttons. I found their effect negligible. Did you play around with that?

I found the "sound" buttons to also be negligible.

Wow, i think that i'm gonna get this in the future instead of the FUN... this one works as a DAC and AMP at the same time, right?

PC -> D100 (DAC) -> D100(AMP) -> headphones ?

post #50 of 1160

Yes, and if you don't already have a good headphone amp, it will give you the ability to get an excellent DAC and a good amp, but with an easy upgrade path.

Yes, i'm gonna get the d100 as a dac/amp, then i'm gonna upgrade the amp section ^^

Thanks!



Yes, it does a very good job with my K702. Perhaps not world class, but definitely good enough to use and enjoy. If I never had a better amp to use, I could be perfectly happy with this built in amp.

What about the power supply, is it good as it is?


I'm not sure I understand the question.... but the Yulong has a well designed power supply. The torroidal transformer is quite large, and although it is phsycially in the same space as the rest of the electronics, it seems designed well enough so that there is absolutely no noise generated. A lot of expensive gear has the power supply isolated in a seperate chamber, but in this case that doesn't seem to be needed.

I have a top-tier IEM (Earsonics SM3) and am considering getting a new DAC. I would not have thought this was the way to upgrade, but after hearing the improvement on my Musiland, I decided to upgrade my DAC. I was wondering if the Yulong D100 works well with IEMs. If it does, is it any better than the Audinst HUD-MX1 with IEMs? Or is it a waste? Thanks in advance!

YES! I'm using it right now with some Unique Melody Aeros and it is top notch. The dead silent background and great channel balance at lower volumes makes it perfect for IEM use. I actually think it is a stronger performer with IEMs than with larger cans.

 

The Yulong is an overall better performer than the Audinst, including with IEMs. Exactly how much better is hard to say. Is it worth a $300 price increase? Maybe. It is for me. But obviously we reach the point of diminishing returns, and that extra bit of performance comes at a price premium.

I thought I did, it's buried in there somewhere.

 

Sound mode 1 is full range, flat response. Sound mode 2 is down about 3dB from 15kHz to 20kHz. Knowing that, I think I can hear the difference with test tones, but on real music the difference is imperceptable. I really wish they had extended it down lower, maybe to 8kHz or 10kHz. That would come in handy with certain recordings and certain headphones.

OK thanks.  Agreed - would have been better had it been a little more noticeable, otherwise why bother.  There is not a lot of music content above 15 kHz, and if what they were after was a bit of a softener, they needed a 3db trough between 5-10 kHz, and then a return to flat, not a top-end roll-off.

 

But still - impressive product for the money.

Nope. Even the most difficult/hissy IEMs like JH13, ES3X, LiveWires, etc, are all nearly silent when plugging in to the low impedance jack.

I have received my D100 today and been listening to it with my LNS, what a neutral DAC this is, really enjoying it already without the burn-in. Also, I can not confirm that the sample rate flickers like Skylab's loaner unit, did you check your power sources?

This thread convinced me to start vigorously selling stuff so i can get my hands on this ;)

I confirmed that this was originally designed as a "feature", but after user feedback, it was changed in later production so it no longer flickers.

Interesting. What is the serial number on your unit?
