A not sarcastic question for the power conditioner/upgraded power cord folks
Power cords is always  a fascinating subject, more so than other cables.  
How often to you clean vinyl and the needle?
Records once if I play them rarely, maybe every year if I play them often. Needle-before playing each side. I hate vinyl and love tape.  
SPEAKERS THAT SOUND ALIVE & DYNAMIC AT LOW LISTENING LEVELS
All good speakers  should sound alive at lower levels with proper amplification.   
A not sarcastic question for the power conditioner/upgraded power cord folks
In my limited experience, power cord from the wall to power conditioner is very important..  I use PS Audio regenerator and experimented with a few power cords. Purist Audio Dominus was the best but I needed it for my amp, Purist Aquila was second... 
What does 90% of the Absolute Best Sound Cost?
90% costs about $100k new, not including room tuning and best record pressings.  
Mullard EL34 that sounds best
Anyway, if I got it right, I will want either XF1 or XF2, and matching is desirable.  
Mullard EL34 that sounds best
Yeah, Brent does have a few used XF1 but they are unmatched, $150 each.

Are they Chinese tubes ?

tksteingraber, a lot of work and some luck. I just see no reason to switch from SEDs to anything but vintage Mullard. Yes, soul and tone.

Did you get matched or unmatched quads of used Mullard XF2 ? $100 for test new is not bad.  
Do military/industrial tubes sound better than regular ones ?
trivema, no I have no intention to buy too many, just two or three sets of each type that I need. Did you compare those Raytheon 12AX7 black plates to RCA blackplates ? Ralph, I see. This makes it complicated, doesn’t it ? You just have to try, n... 
Do military/industrial tubes sound better than regular ones ?
But at the moment I am burning in a new set of regular 12AU7 RCA blackplates from early 50s to compare them to the same RCAs from late 50s. 25 hours of burn-in time so far, but I think I hear something indicating that they might be slightly better... 
Do military/industrial tubes sound better than regular ones ?
By the way, I completely disregarded Kevin of VAC’s advice regarding small tubes. He suggested some selected Chinese for 12AX7 and Brimar or Sylvania for 12AU7. I figured we had different taste, and I certainly don’t want any Chinese tubes in my a... 
Do military/industrial tubes sound better than regular ones ?
Well, Brent from Audio Tubes has both regular 12AU7 RCA black plates and military/industrial ones, all from 50s, not sure early or late 50s. He also calls industrial Command Series. I have regular ones installed, so I could order a set of military... 
Do military/industrial tubes sound better than regular ones ?
Yeah, no doubt, NASA grade, medical grade, scientific grade. But also for guitar amplifiers, organs, TVs etc.
