1) op-amp rolling. SS V5i dual is a fantastic choice. It keeps the details and becomes more musical. The stock opa1612 is also good, at least on the specs, very low distortion. This doesn't effect the line-out.
 
 

op-amp rolling is not so good
Each opamp has its own characteristics and it is better to make new measurements ( noise, THD... ) after an opamp rolling
I love the sound of the xduoo with the stock opamp on my Philips X2, and if you want to modify the sound to your taste, i think it' s more efficient to play with an equalizer !

For those of you who bought the burson op amp, how long did it take to deliver and did you have tracking information? I ordered mine on the 9th and for a shipping confirmation and taking number but whenever I try to locate the package, it gives me an error about an inaccurate trading id. Thanks in advance.

I received an email with  tracking number.  It is dispatching from China.  When I last ordered (the wrong  item!) it took ~3 weeks.

How does the dac here compare to the fulla 2?

I am wondering something about output impedance.
 
It is known that this has 0.4~ ohm output impedance. But I use it with the yellow 3.5 to 6.5 mm converter that came together.
 
How that thing affects output impedance? A person from fx-audio dac x6 thread says that it affects sound quality (making it bad). Maybe this is because that thing changes output impedance so much.
 
What do you think?

Strange ... depends of the converter ?  be carefull that the jack from headphone gots good connection.  And well perhpas a full metal body can
By the way Beyer headphone have native 3.5 mm jack and a screwed 6.3 jack adapter. And nobody has never complain about it.

Good question !
And moreover against the schiit modi 2 uber ? any comparaison ?

The spec I am missing is the actual output impedance.
Any information available on this?

I saw this posted on the first page of the thread, but never saw an answer. Maybe I missed it. Was there ever an answer as to the actual output impedance?

output impedance = 0.62 ohm. Source:

Awesome. Thank you for the info. That makes it an even more appealing product, especially given the price...and thanks for translating the page info from Spanish!

Just dropped a Burson V5i in mine. Easiest mod by far and as dramatic a quality increase as dropping a '54 RCA blackplate in my TA-03.

For those of you who bought the burson op amp, how long did it take to deliver and did you have tracking information? I ordered mine on the 9th and for a shipping confirmation and taking number but whenever I try to locate the package, it gives me an error about an inaccurate trading id. Thanks in advance.

I also ordered mine on the 9th, arrived on the 30th. The RC tracking number they give you will not be scanned by USPS stateside, so all you'll ever see is that it left Hong Kong. Also, you need to add a 0 after the RC and before the first digit. So, RC(0)######## is your correct number. You should be expecting a small yellow padded envelope, maybe 6x6"?

Anyone compared it to Cayin C5 soundwise?

 

[timorinolee]

Just did the V5i mod! At first glance I thought it wasn't in completely but it was. 
 
Loving the improvements! This DAC/Amp is way more musical/lively now.

Bought at GearBest.com. For $ 153.57, I think very good price.
Excellent sound, low solids and clean treble.
Excellent purchase.

 

[killz4gold]

got he XD-05 few days ago, will compare it directly to SMSL M2 and SMSL M3

I have one like that, the d.c. resistance is virtually zero ohm.

Has anyone tried pairing this with the Sony Zx1 via otg/dac? I am on the edge of clicking "buy now". I just need to know if it will be a good pair.
