    Since it's about to  be launched, I thought I'd get an impressions thread started.  If you've heard the WA7TP - and especially if you've been able to A/B it vs the stock PSU - please post your impressions here.  [​IMG]
    I'll prime the pump with some early impressions about the prototype I heard way back at CanJam 2013:
    W. Chi:  The WA7's basic signature remained largely unchanged in terms of frequency response. However I was able to enjoy a very pleasant improvement in transparency, soundstage and separation with the new PSU. And while I can't recall my personal WA7 ever sounding congested, it was very clear that the new PSU revealed a new level of detail, depth and dynamics. I was impressed enough that I reserved the first production unit off the line.

    I didnt expect there is still room for improvement to an already awsome
    Eh+wa7.im gettin my hands on it..any news when they will release it?:)
  3. warrenpchi Administrator
    Not exactly sure, but I'm pretty sure it will officially be available within the next few weeks.  From my perspective, it's already been way too long a wait.  [​IMG]

  5. zniper2984

    Indeed. It's almost like they have other products and projects to work on (curse those WA234 monoblocks that mere mortals, such as myself, are not worthy to touch!).
  7. warrenpchi Administrator
    Hehe, actually the WA234 was already done by the time I heard the PSU prototype... so that's no excuse!  [​IMG]

    Blast! But weren't they still working on the special website? (trying to cut them some slack here...not working) [​IMG] 
    Anyhow...back to the WA7tp.
  9. warrenpchi Administrator
    I like the website, it's nice.  It doesn't make my WA7 sound better, but nice nonetheless.  [​IMG]
    Yes!  T-minus 4 days...

    I hope their stock is enough for all of us..:)

    PSU uses 12AUs so any direct replacement should work , 5814A i know work for sure because i had a chance to try Jan Sylvania ones and they improved bass depth and extension
