I need some feedback, please:
I've actually done some research to see if it is possible for me to take on board a flight (as a carry on) my WA2. I am traveling from SF to Amsterdam anyway so I thought that I could also drop off the amp at Ultrainferno's doorstep or at least at his hotel room's front door. He's been itching to listen to one so I thought to myself "why not lend him mine for a year." I mean, what are fellow Head-Fi'er for anyway but to exchange experiences and occasionally lend amps to each other? Besides, he got me a few 596s and I can only return the favor in this manner. (Also he might treat me to a beer or two in good old Amsterdam.)
Ultrainferno has also helped by calling a KLM rep and chatting her up for more than a few minutes to get some answers regarding this issue. I'm sure he was also trying to get me a discounted ticket. ;-)
By all accounts the WA2's box is in compliance (by its dimensions and weight) so I can bring with me on the plane and place it under the seat in front of me in the economy section.
What I would like to know is: has anyone had any experience taking a headphone amp like the WA2 on board a commercial airliner? I've looked at KLM's website and I think the WA2 could be classified as a Musical Instrument! ;)

Feedback is appreciated! Thanks....

The box is in compliance but in Post 911 skies, if I were you I'd get clarity on content. I would make two quick inquiries - FAA & Jack Wu. Hope this helps!

So I've noticed a couple of things re the Mighty 596.
First of all, for the LCD-2 it remains the top of the heap over my other current favorite rectifier tubes (Princess 274B, PSVANE WE274B knockoff).
But with a caveat: It seems to thrive with the additional power of the Sylvania 7236 power tubes. I have tried a variety of 6080 and 6AS7G tubes with it, and even with the HD800 I have noticed better performance with the 2-watt tubes. The planars themselves benefit from the additional power as well so the difference is greater with the LCDs. I can definitely live with the 7236/596 combo with the 800, but the LCD really craves the 596.
Has anybody else noticed this? I would imaging that the differences would be similar with other 5998/7235/2399 etc, tubes.
This difference in performance leaves me with an entirely first-world dilemma. When I use my WA22 as a preamp, it works much better with the lower-powered 6AS7G/274B tubes, but when I roll in the 2-watt power tubes it's better for me to attenuate digitally. But especially with the LCDs, the 7236/596 rules, while the 800's work great with the lower-powered tube combo as well. So it leaves me with perhaps a wider variety of possibilities that I bargained for, I haven't quite decided yet.
I'm leaning toward simplifying my complicated system by dumping my 274Bs and 6080/6AS7Gs and getting more 596/7236 backups, and finding a DAC that offers attenuation along with a 32-bit sampling rate (finally a real excuse to upgrade my DAC!) So if I want to keep my software setup and habits the same, the Woo DAC is back in contention as the Gungnir doesn't offer digital attenuation.
edit: I just noticed that the WDS-1 only offers 24-bit sample rate. Maybe a couple of XLR attenuators instead...
While I am getting a handle on what power tubes and rectifiers I will ultimately prefer, I am about to muddy up the waters entirely as I have been neglecting the rolling of driver tubes, and I have accumulated a wide variety of those while pretty much sticking to the Shuggies in practice. I swore I wouldn't get like this, but I seem to be under the spell of the OLB's (along with a few new ones). My wallet hates me.

The W4S DAC-2:
Great sound
Upgradeable
3 year warranty
Excellent customer service
What's not to love?
I found these...
I like everything about it, except the form factor. The Gungnir is excellent that way and it's price is right, but no attenuation and no AES/EBU input. The NAD M51 is perfect for my needs (35-bit, 844 kHz!) but even more $ than the WDS.
So the search continues, luckily I really enjoy my existing pedestrian setup. I'll probably just keep buying Old Light Bulbs™ while I think on it a while longer.

Silently, not exactly loving the aesthetics of my shoe-box, but... 
Jack did have them in stock before, he may still have some.
This is crazy, 1K can buy 2 return tickets from HK to Shanghai.
Let me know your itinerary when confirmed. 
Hi,All as i have been reading through is forum now for two weeks and caught the bug, and have just purchased a WA6-SE should be here early next week. It will be interesting to do a comparison to a 339 la-figaro and a stax SRM-1/MK2 Professional, i need more space.
Hi. My next amp may well be the Lafigaro 339 (thanks to Ultrainferno and keph).
imo that is the Computer version of 5998 and somehow looks like a 5998A which i believe Skylab says that its sound is not so good...
...
Btw Clayton, i did bring my WA6SE from Hong Kong to Beijing without any problem. IMO its better not to bring the WA2 over board the plane since it will pass through a lot of security inspections.. When i check-in at the counter i put the WA6SE box so that it could be inside the planes cargo/baggage storage, With this you don't have to bring a 12KG box and through multiple security inspections. The Woo Box is really though, mine was the double box one.. Oh don't forget to ask the Check-in counter for a Fragile sticker to stick on the WA2 box..
1K will fund me a DAC-2 in Hk...Thank God ticket from BJ to HK cost only $400 round trip...
Well let us all know what you think about the comparison between the WA6SE and the 339...i've already got something/thoughts on my mine considering this two amps..who knows my thoughts and your are the same...
