Hi would any of your USB DAC's be asynchronous? hello , thanks for your questions, what do you mean about this ? |

Hello Mike , thanks for that , yes , i hope can talk with you about this , by the way, as soon as we have sample , i will send to you for review , by the way , you mean you do not like the design of the Box , do you have some suggestions about that ? as the DAC is X-series DAC , it will have a DAC and a AMP , waiting for your suggestions . Thanks !

Hi would any of your USB DAC's be asynchronous? hello , thanks for your questions, what do you mean about this ? "The main thing to keep in mind when reading about adaptive and asynchronous USB modes is clocking. Clocking is extremely important with digital audio. Many digital audio experts agree that keeping the clock as close to the DAC as possible, or using a master clock for all digital components is the way to achieve the most accurate sound. In consumer high-end audio as well as professional audio clocking is a major concern and very often external master clocks are used to achieve the best sound. Asynchronous USB DACs are few and far between. Currently Ayre, Wavelength, and dCS are the major manufacturers with asynchronous products on the market. In my opinion the reason for this lack of async DACs is simply because it's very difficult implement this technology. There is a specific skill set required to implement asynchronous USB and it's not common place in high-end audio. Implementing async USB requires a manufacturer to write its own software for the TAS1020 chip and invest thousands of hours on this part of the DAC alone. The limited number of manufacturers who've decided to take on this task instead of going with a plug n' play chip are doing it because they think the performance gains far outweigh the development pain. Asynchronous USB essentially turns the computer into a slave device as opposed to adaptive USB which does the opposite. Thus, an asynchronous USB DAC has total control over the timing of the audio. One very important feature of asynchronous USB mode is bidirectional communication between the computer and the DAC. The computer sends audio and the DAC sends commands or instructions for the computer to follow. For example the computer's clock becomes less accurate over a given period of time and can send too much data too quickly and fill up the buffer. Asynchronous DACs will instruct the computer to slow down, thus avoiding any negative effects of a full, or empty, buffer which can manifest itself into audible dropouts and pops or clicks. According to Wavelength Audio the tail is no longer wagging the dog when using asynchronous USB mode. Plus all of this is done without additional device drivers or software installation." |

I see M2Tech (HiFace) now have asynchronous models also.
And an interesting battery supply.

Hi Candy,
The design aspect is really good. They look serious quality. I must admit, since buying an Aune amp, I have really developed a liking for its sound. I love both the Aune amplifier (which I have attached a gold volume knob to as a sign of respect!!) and the Mini Ape player. I use both a lot.
Can I ask whether the issue of low bit files playing on the Mini Ape has been addressed by any updates? Although I'm using wavs mostly, I do also have low resolution files and have to go back to something lke an Ipod to play them since the Mini Ape won't play the last part of short, low res files.
The update that I installed got rid of relay clicks entirely between tracks but never resolved that particular issue. Or are we to assume that we should only use high res on it in reality?
Rgds
Ian

The X3 speaker looks really nice. (and convenient) I presume that the enclosure is plastic? Are there any retail prices yet, Candy?

Hello Ian , thanks , about the X3 speaker, it is not plastic , it is all MDF board and with piano lacquer appearance , it is 35W , more information i can not tell you as right now , we do not have it for sell , may be need wait next month , this month only the X1 DAC and X2 AMP for sell .
about the X2 AMP , yes , i will send more infromation later , the X2 AMP is more warm than the mini USB AMP , it is also the upgrade version , but without the USB function , as this make the sound more warm and better than before , so the price for the mini USB AMP will be cheaper than before .
More informaion i will post later , thanks

The X-series DAC and AMP are on their way for review (thanks Candy) and I will pass both around to a few of our UK / European members for an audition (as soon as I have completed my own review).... stay tuned!

Must admit I am really looking forward to trying the amp and DAC and the "X" stand is just SO cool.... Candy was telling me that if you buy BOTH the amp and DAC together you will get the "X" stand free.
Prices will be $199USD for the DAC and $119USD for the amp which appear to be extremely competitive (given the specs).

What kind of power supply is included with the units? Thanks. They will be SMPS Miguel... pretty much the standard these days as they are "green" and can work with any input voltage between 90V - 260V.... the AUNE and Mini APE SMPS supplies were actually good quality and I expect the same to be true for the X-series. Mike. |
