Is that a DIR9001 near the Test Point, and a 74C157 above it ?
All looks a littlle cheapo design to me.

It is simple, and sounds better than my X-dac v3 'stock'. Rather have tantalums than a opamp. The reclocker is on the USB as USB/computer tend to have increased jitter. Well, I don't care much, i just wanted to show that short signal path.
It really is sweet and fun sounding. Much better than the AD1955 chip built into the yulong also. But the V2 kind of ruins the experience. If you have not tried this type of DAC then you don't know what you are talking about. It really shows you the colors in the music. But a Meridian upsampling DAC is better of course, also Wadia.

this post is so funny
Krisno : I also tried that specific DAC with the Yulong solidstate, and it was the best I have heard in my life.
so just use the f.....g yulong and sell the v2 to some one that will enjoy it.

The Yulong was very cheap, it is a clone of the Lehmann Black cube linear. But its a very powerfull amp, and no matter what you throw at it, it just sounds extremly sweet and non-fatiguing(typical for the lehmann). OPA 2134 based.
Anyhow... the combination of the very powerfull Yulong + AKG K 701 + NOS dac was extremly good stuff. I really want to like the X-canV2, and its more advanced than the yulong by far. But even so, it sounds still harsh sometmies. It is fatiguing........ but I think the V2 + Sennheiser HD650 and you got match made in heaven.
But it is alot better now than in stock form..
I think.... the way to go is a modded X-Can v8. The V8 was a better amp with the AKG, though lack of details.. but the details can maybe be improved with some good NOS tubes + cap switch. V8 was more lush...

Maybe Yulong has some hidden strengths, maybe opamps is the safer way to go, as discrete is less forgiving in case anything is not good. But the X-canV2 is good, no doubt about it. Even though the synergy / magic one had with the above mentioned amp is not there. But guys, what you people use as source for the X-canV2? What is your source Mike? What about you marayyo? I could buy the Stello Signature, but it is expensive, though seems nice. This NOS dac might be causing some problems? I am not sure... well, I guess the V2 is a keeper as I spend so much time on it  K |

If the Yulong is a clone of the Lehmann, it will use op-amps on the input section, transistors on the output, no global feedback

maybe but re-clock?? Robert  "using matched Philips Silver Crown TDA1543 chipset x 8" Using matched Silver Crown TDA1543's Matched by young blonde virgin's on the top of Mt Olympus too.... [/quote] I'm shocked they all had 8 pins, I'm sure of it ,  [/quote] Why use op-amps with 8 x TDA1543's, it defeats the object of running parallel dac chips |

Leo. the Yulong / Lehmann is so sweet, no matter what you throw at it. Really impressed by that opamp. So maybe opamp is the solution..... less easy to go wrong?
It's almost like I 'saw' the music when wathcing some movie trailers. It was such an experience I have never heard. Yulong + AKG + NOS and just immensingly sweet.

Are NOS Tesla 6922 tubes 'darker' than the Russian's?

reading through the posts, i don't think you'll ever be happy with anything other than a yulong amp. save your money on any more mods/tubes and get another Yulong then sit back and ENJOY  |

hehe... no. The Yulong had its faults. If I am getting anything I am getting the Burson HA100

There is now three and a discrete op-amp module in the headphone section. Dark and smooth like Leo mentions. |

But guys, over to my X-canV2. It has been running 1 week now, non-stop... on some albums it sounds good, but you still notice some sharpess. And yesterday I was shocked. I was listening to Ray Charles - RAY! soundtrack and I had quite a bit of volume on it. 12oclcok.... and then suddenly this 'schreeching' intens painful experience. Like very bright. You call this 'shrilling'? or whatever... But what causes this? Why on earth is this thing not as smooth as the V3??
I am allready using the latest little pinkie. Can it be lack of power somewhere? Or something fundamentally wrong with this?

As already suggested: Send it to Mike for a check!
That would be the swiftest way finding out what the fault is. Something is wrong if you feel you have to exchange every single component.
Just a friendly advice.

It is very cumbersome for me to do so, so I'd rather not.

But this X-canV2 really has some major distortion. Hear it constantly, it really wrenches the sound on the top octaves. Secondly it is generally very bright. Even when using a warm and 'dark' DAC. I really am shocked that I alone are experiencing this.

Is there anything you do like about the V2 Kris? With diy if I find a certain unit sounds very bad to my ears in stock form I'd personally scrap it and move onto something. It seems pointless wasting time on a product you don't like at all Just my opinion |

I think you've already mentioned it before in this thread Mike but first thing I'd do is try an alternative source just to be sure and another pair of cans too. As hinted further up the op-amp in the Yulong amp is quite dark and smooth, it maybe covering up problems further upstream It does seem odd the majority of people who own the V2 don't accuse it of being bright, I'd imagine Miguel would be one of the first to say if it sounded bright? Is it possible Kris is pushing the amp too hard and causing it to distort? I know the AKG's can give a sharp HF response if the amp used is pushed harder than it can cope with. Either that or his amp does have a fault somewhere. If it was mine I'd load it and look at the output on a scope but I understand not everybody has one |

Guys!
The V2 was distorting and very bright / harsh even before 'mod'... it is somewhat better ater mod and tube swap and psu, but not by much. But when its 'good' its the perfect amp. It really 'shrills', the V3 never did this.... so a output transistor swap??
I just orderd the Burson HA-100 amp...... killing my wallet but well, what the heck.

Wish you more luck with the Burson amp Kris, if you don't like that one I'd give headphones up or buy another Yulong  |

Post by krisno on Feb 15, 2009 21:32:29 GMT
But something is really wrong here. But maybe that gain mod is what needed. Don't understand why its such a let-down, and sound so different from V3.
Noone of you guys have any clue?
K
P.S. yes, the burson will be the last amp I ever get for headphones. It's like my 5th in under 1 year. AKG's are hard to get good sounding. But Yulong(OPA 2134) + nos was good, i should not have sold the yulong, but I wanted tubes..hehe.. and well..
