I hate to resurrect a thread this old but I wanted to share a recent discovery. I tried a few materials for this mod and I found that the fuzzy side of industrial Velcro from Home Depot has the best absorption properties for my system. What is really cool is that the Velcro already has an...

I auditioned the 2nd generation T5P over the weekend. I was shopping for a travel/office headphone so the primary criteria were: 1) must be a closed headphone 2) must be able to be driven by an iPhone and 3) must be comfortable. I A/B compared a bunch of headphones from Sennheiser, AKG, Audeze...

Here is what Jack Wu had to say about it: Quote: The WA22 is a fully balanced amp, see diagram below. The question here is that this amp is not fully balanced because the "amp with a single ended output stage directly connected to the XLR connectors.” It is not true. In an Output...

I'd just like to clarify something: the 1/4 output in the WA22 is technically a balanced output.

Respect!

that's too bad. It's my best car on Forza...:)

That is very tube-dependent.

I don't have a Veyron but if you live in the Midwest, you can drive my McLaren F1...

I'm using National Union 6F8G VT-99s. The 6SN7s that came with the amp were much noisier and over boosted parts of the frequency range. The 6F8Gs may have less gain (somebody fact check me on that please). I found that I had to turn my volume up a bit to get the same apparent listening level...

I just got some Woo adapters. Much better than the others I tried: one pair broke at a solder and the other ones didn't fit! Also, the Sylvania 6F8Gs are underrated.

+1. The WA22 with the right tubes is the best amp for HD800s. Prepare to spend up to $1k on tubes though! Still, I prefer a tubed-up WA22 to the WA5 for the same coin.

Good point. The top end can be rolled off with certain amps/tubes, too. I would point out though that HD800s aren't the poster child for authoritative bass reproduction so those that favor HD800s tend to be indifferent to that sort of shortfall. It also bears stating that tube selection can add...

There are a few things to consider beyond what has already been mentioned. First, the price of tubes should be considered. A WA6 with upgraded tubes sounds much better than the WA7 with the stock tubes for the same money. Second, the WA7 does not require cables between the DAC and amp. Figure on...

I can polish your Woo amp to a show-quality mirror finish. I have an Eximus DP-1 DAC that's got a mirror finish. I'll post pics tomorrow. The best part: no finger prints! I $hit you not. I have a special finishing process that resists fingerprints. If anyone is interested, let me know. I'll post...
