The problem is trying to properly and coherently express what this thing can do and comparing it to anything else I've tried seems like a fools errand. Regardless, I'll put pen to paper and see if I can explain this thing...somehow.
To answer your question regarding my decision making process, the short answer is both -it was both quite involved and quite risky. I initially began by soliciting opinions from a wide swath of people, say twenty or thirty from four to five different audio forums, then began distilling the recommendations down into a short list of options. It quickly became apparent that the WA33 was the best choice as it was
by far the most recommended, especially for the Abyss AB-1266 Phi TC headphones I had already planned to own (FYI, the Wells Audio Headtrip II was the second most recommended). Unfortunately, there weren't a lot of reviews and information out there for the WA33 (especially for the EE, the JPS edition, or both) so I reached out to multiple vendors, dealers, and owners for more information. Despite the numerous glowing recommendations for the WA33 (yep...that was a tube pun), I had more or less settled on the Wells Audio Headtrip II. This was mostly because I was afraid of tubes and subsequent tube maintenance. I reasoned that if I was going to spend 15-20k on an amp, I sure as hell wasn't going to get something that I'd have to keep pumping money into to maintain over the long term (LOL@littlej0e trying to be "sensible" when considering buying a 15k amplifier).
Then...as fate would have it...I just happened to come across a certain gentlemen by the name of
@Ciggavelli on a forum called head-fi.org. It turns out he has the exact same condition I do (synesthesia). He was the only person I found throughout all of my research and solicitations that truly understood what I was trying to build and why. Furthermore, he built his system for a lot of the same reasons, so he was an absolute goldmine of guidance for my very unique use case. When he recommended the WA33 EE JPS, and explained his reasoning behind it, that was the final nail in the coffin -I had to get the WA33 EE JPS.
Edit: I will add that I did get to try the stock WA33 at a local dealer. It was good, but the EE JSP edition flat out destroys it by a country mile. The stock WA33 and the WA33 EE JPS aren't the same amp at all. Not even close. So if you do go with a WA33, definitely get the EE JPS edition. Also, for reference I did get fully upgraded tubes: (4 x KR Audio 2A3 HP Power, TA-274B 1 x Takatsuki Rectifier, and 4 x 6C45Pi Electro Harmonix Gold-pin Drivers). At this point, It would be difficult to recommend another configuration based on my experience thus far. But for giggles, I'll throw in the stock tubes and have a go.
Lastly, my wallet feels your pain. Trust me. Mine is currently on life support...
