Did you go through about a 10-20 hour period where it sounded kinda bad recently? If not then you're only at stage 2 of 5 in the break-in of the Spragues. Stage 1 sounds smooth but not very transparent, Stage 2 opens up the sound field, stage 3 sounds bad, stage 4 is where it goes smooth again but doesn't have transparency yet. Stage 5 where you'll fall in love with the amp. It happens pretty fast too, making it even more fun.

This appears to be the third different presentation I've heard since I've taken delivery and pretty much settled on the 3DG4, 5998, TS-BGRPVT231 combo. Sounded a bit rough the last two weeks and as a result, I put very few hours on it due to not feeling moved. Now starting to mellow and become more identifiable. By your assessment, maybe I just entered the tunnel to Stage 4.
We hung it up this morning @ 133 hours. It seems that 150 hours to 175 hours may bring joy. But not peace... listening at volume 10!

Although, I've no idea what the amp should sound like in full sonic bloom, it's easy to tell I'm not there yet. But, feel I can't be too far off either. And having 25 ohm cans, the "X" mod may have more of an impact... perhaps, slightly. The output impedance should drop down to 20 ohms; Glenn informs it's currently 40 ohms. The "X" mod could be the sonic wave I've been waiting for!

So these amps have names now?
Sprague is a brand of capacitor, mostly out of production now.
My amp really does not have an official name. It would be nice if there was a brass tag of sort that either bears Glenn signature or his trademark. I really enjoy the amp much better since it came back. It is much more relaxed and smoother sounding with my new current setup.

I'm not into naming my car. Or naming the dog... wait, ain't got one - no cats-cows-chickens either! But anyway, having observed Glenn's custom builds, I just we could use a name or model number to make it convenient when conversing. Or "Slinging it around" while posting, as I originally put it. 
The story behind "Silver Hawk?" It's a play on the Black amp having a Silver face and "Kitty Hawk" for those who know the studio's location.
Are you going to commission a custom build (wicked?) later this Spring/Summer?

Sort of like how the engines are tagged on the AMG or Brabus Mercedes I haven't bought yet. A single Master Engine Builder puts the whole thing together by themselves and then tag it with their brass signature plate - "Built by..." It really is a nice touch!

This was my goal for 2012 originally - forgo new purchases but optimize the entire system. This is also why I let the Woo go, so I could fund the purchase without giving up new money. And the system has no shortage of areas to improve on. If anything, I'd be wise to improve on my battery sources - the rabbit hole is getting darker... and deeper!

Mercy! I wonder what the "Triple" sounds like in contrast to what's in right now. Does the extra getter influence the sound at all?

THat's a great photo, love the tungsten reflection on top.
And I do appreciate 2359Glenn, I don't have any of his amps but his tube adapters are top notch. Plus he is very knowledgeable re compatibility with Woos, is easy to work with and ships quickly.

It is a great photo! The way he staged it, The Chief looks very intimidating. I might have to buy it just to hear it. 
I currently still using the double halo getter in my current 3DG4 tube as my primary. If you look carefully on my night picture you can just make out the double halo hovering over the filaments. Having any getter on the top makes the tube a bit taller. It makes a small difference in the tautness of the sound far smaller than changing to the 5v rectifier tube. Having extra getters may help with the manufacture to have a better vacuum in the tube. Also I noticed that some 3DG4 tubes seems to have a bit less fatigue over longer periods of time in operation. I noticed that effect a bit more in the 5V3A tube. I do not have a tube test socket to see if I can point what I am observing out on paper. I noticed that Glenn has his "member of the trade" profile approved.
