Yeah, I think it is about time I canned my complaining.  My apologies to everybody for filling the thread up with it.
 
Back to your post longbowbbs, that seems like one heck of an amp for $279.  They must have come up with a pretty original topology to get performance like what you describe at such a low cost.  I'm guessing it has an external PSU..... is it a switching style or traditional linear?

Last year, you were kind enough to share what direction you were moving in with headphones. I was excited then as I am now for you. It seems the new cans may not serve as anticipated. But, I was previously made aware of your sensitivity with headphones in general. And applaud you for stepping away from the venerable K701's to give the LCD-2's a shot. 
 
Have you considered their return with a restocking fee and starting anew?

The last two listening sessions showed great promise actually, with the exception of piano pieces which are being problematic for some reason.  I think I have forgotten the need to be patient with new headphones.  They may be exposing limitations not previously evident in my upstream signal chain too, something I should have been more prepared for.
 
Things will work out somehow.

Does anyone have any experience with RCA 6SJ7WGT Mesh plate tubes? My tube guy is out of TS 6SJ7GT and recommended me these ones, also mesh plates.

Can he send you pics that you could post? I don't think that RCA actually made mesh shield 6SJ7GT's. while I have some that are branded Raytheon, I believe that only Tung-Sol made mesh shield 6SJ7GTs in the USA. Later, Hitachi made them in Japan, too. I'm not 100% certain of this, of course - tube history forensics are just based on research, and theories can always be debunked by new evidence :D

Here is what he sent me, they do look great! What do you think Skylab?

Yup, those do look nice...and they look EXACTLY like Tung-Sols. It's still possible that they are RCA made, but I'd bet they are not. Either way,if they are not stratosphericly priced, I wouldn't hesitate.

That doesn't seem too bad, based on what the TungSols have been going for. The days of getting those for $8-10 each seem over, for now...

 Urgh.  I am usually paying at least $8-10 for the shipping alone.

You can get 6SJ7GT's for $12 NOS from places like TubeDepot, but you don't know exactly what you are getting. Buying tubes from Tubedepot can be fun - kinda like playing the lottery. You can get NOS 6F8G's for $8 each. It's unlikely that you will get TS BGRP's for $8, but I can tell you from personal experience that you MIGHT :wink:

Ok, take $11 average for 1 tube + matching, I'm sure that costs something as well. Let's say $27 for a pair of mystery 6js7GT tubes. Then add shipping to Europe and I'm sure you'll be very close to $50 for a pair in stead of the $30 you guys would pay.
My tubes will cost more but on the other hand, I will get awesome looking tubes from RCA! (I have to tell myself something

Well, I got my 596's from you and they were made in the USA and shipped to me from Europe!

You can also try with a adapter a 6J7G the same tube with a grid cap like the 6F8G & 6SN7 or the 6 pin 6C6 with a adapter also the same tube.
also the 7 pin miniature 6AU6 is the same tube
The first one was the 6C6 then came the more modern 8pin 6J7G and then they left out the grid cap and made the 6SJ7G then came the
miniature 6AU6.
  I don't know the sound or the prices on these tubes but usually the older the tube the better it sounds but more noisy.
