    mmm.....just got word from the Singapore dealer: late April delivery (from mid-April) for the WA8. Is there a fast-forward button I can press right now????

    These two adapters from Apple would work. *** important to buy them from Apple only. There are a TON of counterfeits on the web.
    For USB cable, we recommend Nordost Blue Heaven or Heimdall2

    I am reviewing the WA8 for our local distributor at the moment.

    One question: is it normal that when the WA8 switches off, it emits a loud POP into the headphones?

    Other than that, this little baby sounds marvelous. Am a bit perplexed that it really drives IEMs as well as my planars with ease.... Review coming soon.

    Can one argue that using the apple CCK will cause a bottleneck due to them using a lesser quality cable than nordost? Of course I am just saying what all cable believers thing, I frankly Am not too worried about such things.

    IMO, you can counter the degrading effects of CCK by using a USB decrapifer and a USB to SPDIF converter. The decrapifier and the spdif converter will ensure that the real time jitter is as minimum as possible before it goes to the DAC

    mmm......I am using AudioQuest JitterBug for laptop usb out................not really sure if it helps but it is a just-in-case thing for me.

    Pretty cool review dude. Thanks.

    new WA8 video.

    It is a soft 'pop' when power cycling the amp. This will not cause harm the headphones or the amp. We recommend to disconnect the headphone if the soft 'pop' bothers you.
    Important: when switching between 2 or 3 tube mode, turn OFF the amplifier first, this resets the output. Otherwise, you may encounter distortion in the sound.

    Isn't this thing a bit big for portable use?
  12. gr8soundz
    So, when switching from 2 or 3 tubes, we'd first have to remove the headphones (to avoid the pop), turn off the WA8, hit the switch, turn the WA8 back on, then reconnect the headphones?

    Don't confuse portable with transportable. They never claim it to be portable but transportable and that it clearly is.

    Portable use - it's 2 pounds (1.1 kg) - only for orks.

    The switching off between tube modes was known to me. That the soft pop is by design - hmmm, ok. I am not saying it's headphone damaging but it definitively scared me when experiencing it.

    If you are saying the pop won't cause any harm with headphones, I believe you. I will update my review with this information. I still think it's a major flaw for a device of that price range to do this. But again, if that is the price to pay to enjoy the a,along sound this thing produces. So be it,

  15. Koolpep

    Yes. That's what I wrote in my review. That would be the process.

    Since Woo Audio has acknowledged the pop is in all units but is not harmful to headphones and just a scary annoyance, I guess that's the flaw of an otherwise pretty much perfect product.

    Anyhow. Once I get the WA8 in my hands again (Friday during a meet) I will record the volume of the pop.

    I must say: it really took me by such a surprise that I was scared - the pop wasn't pleasant.

    Anyhow, good to know its not harmful but the tube mode changing process is odd.
