By June then (hopefully)!
 
The U18 needs software drivers for both PC and Mac, something to take into consideration.

That kind of sucks, because it means no hooking up Androids... sigh....

I am ordering two with the external power supplies at the end of this week.  Will post when I get a chance to try them out.

I'll be looking forward to your review. I am on the fence right now. BTW, will you be hooking it up to the Yulong D18 DAC?

The U18 will be waiting for me when I get back home in about a week.  I am purchasing the external power supply as well.
 
Yes, I will be hooking it up to the D18 as well as to a Consonance DLinear 8.  I am currently using a Consonance USB to SPDIF converter on the DL8 and a Squeezebox Touch for the D18.  I will compare the U18 against these units. 
 
I will connect to the DACs via AES EBU and coax and note if there are differences.

Sounds great! If you don't mind me asking, where did you get the external power supply, just in case I might need to get that as well?

I ordered the power supply and U18 through Grant Fidelity.  You can see the option for the power supply on the U18 product page.  The power supply is a 3rd party accessory and not directly from Yulong.  It costs an additional 75.00 so I assume it is of decent quality.  I will post on the specs. of the power supply when I look at it.

Have you seen a picture of the power supply yet?  I wonder if you can get your own 3rd party power supply to work with the U18?

 

[project86]

We'd just need to know more about the specs it requires. There are plenty of aftermarket PSUs out there, though some cost more than the entire U18. The $75 option seems priced well if it is of decent quality. 

 

[preproman]

I agree.  That's what I was getting at.  Most times you get what you pay for.  $75 uumm Like you said we need to see the specs.

 

[mrcasey]

Expecting delivery Oct 8 or 9.  I will post pictures and specs. etc as soon as I have the U18 and PS.

Excellent review Project86. Your comments convinced me that this was the DAC for me so I bought one. When it works it is great but...... it has a problem! it only works about half the time you switch it on. Sometimes it lights up and the signal LED lights to show that it is receiving a signal, but no sound! I have tried both optical and AES/EBU inputs with the same results. It is as though it is locked up. Are you aware of this problem and can it be easily fixed?
Thank you for your assistance.

I noticed that the signal light seems to indicate the active line in by connection it does not function as a signal lock indicator. At least that is my take on it. I have the D18 and it never fails to work as intended. Before you assume that it is a fault with the D18 you might want to do some checking of the signal down the line. It is always possible that you were unlucky and got a defective unit. It can happen with any new equipment but from your description it really sounds like you may be losing the signal at the computer side. More information about your system might get you more help here.

 

[project86]

Agreed. Not that I want to come across as sounding dismissive or blaming your source. But it really would be wise to try another DVD player, or direcTV box, or anything with a digital out, to see if you can replicate the issue. In my experience when a digital receiver fails it tends to completely stop working rather than work intermittently.
 
If you confirm with multiple sources, then you know the D18 is to blame and can contact the seller for replacement.
