Two Cents from a Noooob...
Received my WA7tp about 3 weeks ago, but waited on posting this to ensure enough time had elapsed before I offered my opinion.
As a new Woo Audio customer, I must say I’m pleasantly surprised with the quality of their workmanship and the difference the TP makes is quite noticeable. Forgive me if I do not yet know all the cool lingo, slang, and idioms that provide the
audiophileism factor to gear descriptions and reviews, but I’ll try my best (SMILE).
Let’s start with “the bad”… For as much praise that I give to the aesthetics of both the WA7 and WA7tp, I am admittedly disappointed with the TP’s push button, which almost seemed to be an insult to such an exquisitely built unit. When I received my WA7, it felt and looked like a piece of art to me, from any direction, and turning its buttery-smooth knob solidified that impression. The WA7tp’s power button (in contrast) does not feel stable, unnecessarily turns, and overall detracts from an otherwise flawless design. I can definitely see Woo addressing this following their next revision.
Upon unpacking, setting up, and turning on the TP for the first time, one of the tubes [stock pair] (like others have described) created a bright white flash – is this arcing? Being new to tubes in general, it made me nervous especially considering how much money had been poured into the WA7 + WA7tp system. After about a 15 minute warm up, I elected to proceed with a listening session and my frown began to quickly turn upside down. Quick note, I run HD800 cans and EH Gold upgrade tubes on the WA7, set to LO-Z, and use the WA7’s DAC via USB . I listen to just about everything except metal and country.
Yay! That’s the only “bad” I’ve got, all the rest is pure joy…
Here’s the best way I can describe the transitions I’ve noticed with the changes made up to this point:
- The EH Gold tubes on the WA7 added a tightness to bass, more defined mids, improved (IMO) soundstage, but also a tad more sparkle – something that bothered me a bit on an already bright pair of cans.
- The WA7tp (with stock tubes) made the bass appear to be even tighter, mids sound more pronounced, and the biggest surprise was how it shaved off the top end sparkle just enough to truly allow me to fall in love with HD800s. Loving the improvements thus far, I was eager to see what additional burn in time would give me on the stock tubes. But I have no patience, so….
- Enter the Sylvania JAN 5814A (110/110 | 110/110) tubes. As another Head-Fier stated in so many words, these tubes just make everything better, and it’s the truth. I think, generally speaking, HD800 owners tend to want a bit more bass for our beloved cans, and I was shocked with the results from rolling in these tubes. I get all of the clean, tight, and accurate bass from the previous upgrades, but more of it – and not in an obnoxious way at all. I even had to check my EQ to make sure everything was still flat when I started listening. The low end goodness was first evident when I’m Trippin by Millok came across my track list. I did, however, notice an increase in brightness / sparkle which I wasn’t overly happy about (at first) – but considering the improvements in every other category this was a small price to pay. In a perfect world, I’d take everything the Sylvanias gave me with the “top end refinement” of the stock TP tubes – but bear in mind, this is just my own personal preference. I also don’t get bright white flashes with these tubes and have more than 90 hours on them as of this post (the cans were previously burned in with 80+ hours of pink noise).
Loving the HD800s has been quite a journey for me, an acquired taste if you will. Seemingly each element changed in the system has been a clear improvement – the EH Gold tubes, then the WA7tp, and finally the Sylvania tube swap. That additional sparkle I mentioned earlier is somehow getting smoothed out with each passing day and listening session – call it placebo, call it auditory adaptation, or call it what I do: A surprisingly delightful combination of components all working together symbiotically to deliver some of the best musicality you’ll probably get in this price range…
Oh, one other side note: I (luckily) did not experience any of the color differences or height variances between my WA7 and WA7tp (silver finish). Also, if you want to keep that dead silent, pitch black background, be sure to separate your two units at least 8+ inches apart or be prepared to hear buzzing in your cans.
Apologies for such a long-winded post (especially from nooobish material like myself). Happy hunting fellow head-fiers!
