I have tried the HE6 from the adapter box using the WA5 and 845 SET amp - I prefer the K1K output in both cases. Sorry if my earlier posts didn't make that clear (English is my first and only language, but sometimes it is hard to tell 

).
 
For me, the WA5 K1K output beat the WA5 adapter box significantly. Hard to be specific, but I wasn't getting that visceral body to the sound as much with the adapter box and some of the dynamics seemed to suffer also.
 
The 845 SET with the adapter box was much closer to the K1K output, but I still prefer the K1K output.
 
I can only guess that the resistors in the adapter box meant that the HE6 was struggling to get all the juice it needed. It does take significantly more gain to get the same volume level via the adapter box than via the K1K output on the WA5. Perhaps wiring directly to the speaker posts would change that, but I'm not sure that is a good idea with a tube amp - not a risk I want to take when the K1K output does such a great job.
 
The 845 SET amp driving the modded HD800 via the adapter box is a revelation. I find myself drawn to it - wonderful sound without the weight of the modded HE6 on my head - the headphones really do disappear and you float away on the music. My modded HE6 is still the best performing headphone I have, but the 845 + HD800 rig comes close, with much better comfort. WA5 + HD800 via the adapter box is no slouch either.
 
Very happy with the outcome as my HD800 was a little unloved before trying it via the adapter box. Now I have huge respect for it.

 


English ismy third language, so I can always use that as a crutch--or was excuse the word I was looking for?

The HE box use a 10-ohm resistor in parallel (to protect the tube amps, mostly). It uses a resistor in series as well to reduce the output to the HP--in my HE box, it measured 24 ohms. This may be what reduced the gain in your experience. You can easily replace that with a lower-value resistor.

Thanks for the info. I'm happy with the box as is. It works beautifully with the HD800 and I am more than satisfied with the HE6 from the K1K port.
 
Happiness for both headphones - now what do to with the LCD-X? I'm hoping that my 430HA (when I get it) will provide a great pairing.

I have question for all owners of the WA7, Lets say you were planning to buy a new Woo amp for an upgrade to your current WA7, Which Woo amp would you consider. The fancy WA5 & WA5-LE really goes without saying unless that the only upgrade you have in mind.

 

[Stereolab42]

  Problem solved...... it was the 6f8g it distorts past 12 on the volume wheel - not that I ever listen that loud. Actually maybe with speakers I would push to 1 o'clock and I suppose that I'll have to use different 6sn7 for that purpose.
 
Has anyone else had 6f8g clipping??  

 
I had this exact same problem with 6F8Gs in the WA5, the problem was the adapter. I was using the brass-base adapters, they had a grounding issue of some sort. Once I switched to all-plastic adapters, no problem.

 

[Sko0byDoo]

My take,
 
The lust-for-WA5/LE will always bug you if you get anything less.  So might as well cough-up the doughs and get it now.  Besides, why get WA22 now to later upgrade to WA5 (just waste more $$)?

Very cool.

 

[Stereolab42]

Yup. Anyone with a significant investment in tubes should get a good tester.

Problem solved since that post - I had to pair the 6f86 with a glenn adapter. By which I mean there is a right a left on the 6f8g tube and also right and left on the adapter. I had the adapter in the right and left slot but the tube was configured - left in right and right in left.
 
So I fixed it ¬
 
right tube in right adapter in right socket - left tube in left adapter left socket 
 
 
It was totally my own fault for not reading the message properly. All is good now and the combo sounds amazing!!!!

I have never heard about that. I have been using 6F8G tubes and Gelnn's adapters for years abd have never heard about specific tube and adapter per channel nor I have had a problem switching them around. Hummm

Have you used TS BGRP 6F8G? this one seem to be sensitive with Woo WA5.  I've been having the same problem using woo adapter, but glenn adapter fixes it for me.

 I agree. 5 years ago I decided to get a Woo amplifier and since my systems are fully balanced I had my sights on the WA22. I went to CanJan in Chicago just with the purpose to listen to the WA22. Met Jack there and listen to the WA22 with my own balanced T1 headphones first. Jack told me that I should listen to the WA5-LE that even it is a single ended amplifier it is superior than the WA22.
 
Fortunately I had with me the matching adapter to my Zeus balanced cable so  I moved over to the WA5-LE and wow! it was a significant difference. I have never heard the T1 sounding that good. I went back and forth between both amps and not long after my mind was set. I was ordering the WA5-LE (the HE-6 were not even out back then otherwise I would have ordered the WA5).
 
The following week I crossed some emails with Jack and end up ordering the WA5-LE with electronic parts upgrade, sockets upgrade, tubes upgrade, WBT Nextgen RCAs and even send him Neotech OCC Copper wire and Cardas Eutetic silver solder for all the internal wiring. 
 
I still love my amp!

Yes, I have two pairs of the TS BGRP and two pairs that are TS rebranded.
 I had the Woo adapters too (at the same time with Glenn's) and the Woo weer inducting noise. I sent them to Glenn and he replaced the wire for the grip cap for a better one and the issue went away. Since then I sold the Woo adapters and stayed with Glenn's.

The EML 300b's have 11 hours on them now - they are nice and silky, such an improvement over the stock. 
Listening to ray charles - come rain or shine.............. man this is the life!!

Glass encased dog droppings would be a big improvement over stock tubes

 
Congratulations on entering the world of 300B tube rolling. Your ears will love it, your wallet will not
