Woo amps tend to be overpriced for the performance they offer, don't get me wrong they are very well made, beautiful and good sounding amps, but
you can get much better sounding, higher quality amps for the money.
Like the ZMF Pendant (Apmsandsound), the DNA Starlett or Stratus which will both be on a whole nother
level soundwise for around the same price.
I own a Wa22 myself but had to invest over 600€ more for NOS tubes to really make it sound excellent.
I will be selling it soon, since I managed to snag up the very last original Eddie Current Studio Junior that is being burnt in at this very moment.
It cost me 2800$ without 300B tubes but is on par with amps that cost up to 10k or more.
The Wa22 with upgradeed tubes would cost me 3000€ at least and would not even come close to the Studio Jr.
You basically get what you paid for - in Wa22's case a good sounding amp with a beautifull chassis milled out of expensive aluminum blocks that have to be scraped if there are mistakeswhich you pay for.
Just get the ZMF Pendant or DNA Starlett/Stratus and save yourself the money and time spent on experimenting and buying a custom amp later anyway - like most who owned a Wa22 did.
Zach and Ampsandsound made specifically it for the Verite and ZMF cans, plus it is strong enough for most planars out there:
Or the stratus (he talks about the cable but mentions the amp), one of the best amps in the world, true high end:
And here we have the wonderful DNA Starlett impression thread on "another" forum:
