It is exciting to know that the owner of the LaFigaro factory follows this thread so closely that he almost instantly noticed my comment about the price change. It is also comforting to know that he had a good reason for the increase. I really like this guy.

+1 iagree..more facturers should do the same!

I agree on a lot but not with everything you say. In example, the HE500 is very well known for it's good sound stage, it's one of it's strongest points.
You should try the HE500 on the 339 without 5693 but with ef80 or the 6SJ7GT mesh, it's a different story. Also when using the 5998 the midrange will become more forward as you described, that's why I stopped using those tubes in the 339, the overall sound is just easier to listen to when using RCA's or Chatham's; making it better for the HE500 as well.
 
The V200 and 339 are both great amps for the HE500, it just depends on your personal preference a lot. If you can listen to the amp combinations before buying it, I think that's the safest way to go.

 
I also found that Western 6AS7G have really good in the overall presentation and the best with the 339 to my ears, but what I have noticed and made me really poorer, is that GEC 6AS7G have such a 3D depth of sound that surpass the average 6AS7G... The sound has another dimension added to it, I really would love those tubes to be cheaper!
The pure triodes 6J5/L63 also beats both Tungsol 6ASJ7GT and EF800, the sound is more detailed, the separation of voices is more refined, you loose the more dynamic bass of the EF800, and the special midrange of the mesh 6SJ7GT...
6AS7G+EF800= high gain
6AS7G+mesh 6SJ7GT = medium gain
6AS7G+6J5= medium/low gain
 
Overall I found out that you adapt a lot to the sound you hear, and that you wanna hear, but tube Rolling is pretty fun game ^^!
YMMV.

what's a good value, recommended tubes for hd650's ?? 

 

[telecaster]

western 6AS7G NOS and EF800 telefunken, and with HD650 you are there!

 

[wazzupi]

so I went ahead and purchased the RCA JAN 6as7g's with the 6sj7 power tubes I hope they pair well !!

Change all the yellow power resistor.

Noninductive Resistors

I had been heard it. Like change Shuguang 6N5P to Tungsol 6080 than before. Sounds more Clearly and pure.

If we purchase the 339 from an ebay seller (wsz0304), will we receive the new unit?

Dear Boss,
It would be a great to share the Rosenkavalier progress here! I'm sure you would gain some customers!
I'm dying to see what the production model would look like!

Also do sample in design, a complete will send you photos.

Is it possible to mod the 339 to the latest un-named amp?

 

[telecaster]

Thanks a lot boss! Looking forward to the Rosenkavalier

For anyone who is interested I have impressions on TS6SJ7GT mesh plates vs 5693 red hots. The main difference is I find the 5693s having a more forward presentation of sound - Vocals are more in your face - a little too much. I much prefer the TS6SJ7GT mesh plates sound in that regard - vocals sound a little more laid back and hence a seemingly smoother sound. That's what I wanted when moving to tube amps and thus I prefer the TS6SJ7GT tubes; on my HD650s that is. They also helped a lot with taming the HD800 brightness. Though HD650 still my favourite headphone at the moment.

There's also TS6SD7GT mesh plates! They look exactly the same as the TS6SJ7GT mesh plates.  Anyone know if there's actually a difference in sound?
