YULONG's new U18 USB 24/192 Async digital Interface - Page 4

post #46 of 161

I want to comment that the build quality on the U18 is first rate. It is definitly on par with Yulong's other top line products such as the A18 and D18 and is quite at home sitting next to those units.

 

I can comfortably say that the sound quality is slightly better through the U18 when using the external power supply. Not a "night and day" improvement but a noticeably quieter background is apparent. I suspect many USB converters would benefit being removed from the noisy power environment of a computer but not all offer the option.

 

Though not a specific benefit of the U18 alone, I also appreciate having access to native 88.2khz and 192khz bitrates and not having to resample them.

I'm ready to order one.  How long do they take to deliver to the states?

post #48 of 161

If you are ordering from Grant Fidelity Rachel will be able to answer that question for you.  When they ordered mine for me there was a Chinese holiday and a local holiday slowing things down and it took about 7 days to arrive in Calgary.

I was just talking to Ian and Rachel about something unrelated and asked about shipping:

 

"shipping is on normal 5-7 business days now since holidays are over and Christmas rush hasn't started yet"

Cool,

 

Let me check out the web page.

What are the sonic differences between the u18 and your opera unit. Would you say it is better just at playing 16bit files.

I need to qualify that I do not have the "Golden Ears" that some members seem to have, enabling them to hear something as subtle as butterfly wings from 100 miles. :)  I feel more comfortable commenting on functionality.  That being said, I am able to hear well enough, IMHO, to distinguish good from bad at least.

 

In my opinion the Consonance is a great converter and nobody should let its price fool them.  I was quite pleased with its performance.  My main reason for changing to the U18 was to have access to my 192khz files to see how they sound through my DACs.

 

When I installed the U18 in my 2 channel system (where the Consonance converter lives) I did not notice much, if any, difference.  I thought I noticed a quieter background.  This might have more to do with the effects of the external power supply than anything else.  The Consonance USB converter is a very good unit.  So is the U18.  My exposure to the change was limited as I was quite busy last time I was home.  After more time doing some A/B I will report my findings.  In fairness I will use only 24/96 files when comparing both units.

I was considering connecting my Touch to a V-Link 192 + AQVOX power supply to improve the sound. But now you've got me wondering...the Touch is more user friendly than a PC/USB converter setup so if there's nothing to be gained soundwise what's the point?

The V192 does not have the option of connecting an outboard PSU, it's USB-powered only.

Purring away making music!  I have had it running 12 hrs a day for about 7 days now.  This my "away from home" rig.  The A100 amp is new as well and is breaking in with the U18.

Cool - so it passed all test so far.  What is your preferred output of the U18?

Yes, so far there have been no playback issues. I use the AES/EBU output from the U18 to the D100 and to my other DACs for that matter. I will be picking up another U18 to permanently live in my 2 channel setup so I don't have to switch out. I have not done enough A/B with the other output options to honestly say the AES/EBU is my "preferred" method but it seems to be the preferred method of many when given the option so I went with it.  I play all files at their native Bitrate and Bit Depth.

I wonder - is this converter on par with V-Link V-192? Anybody have both? Yulong looks better because of opportunity to connect external power, but V-Link is XMOS unit after all...

That's what I was afraid of - issues with the drivers opposed to the XMOS or USB32.  So far no issues have been reported.

No, i didn't mean driver issues (I just hope I'm lucky enough wink_face.gif), I meant pure performance of them. V-Link doesn't require a driver at all, as I know.

The V192 comes with a Windows driver disk.
