Congrats. Welcome to the HG club. I'm at around 40 hours on mine. They have definitely opened up since first listen. The best purchase I've made yet. Mind=blown. Lol

Welcome to the 6N23P fan club!
 
The '75 Rockets are a bit different then the HGs.  The HG's are '75 Reflektors - a very, very rare version with a single wire getter post and silver shields.  The "75 Rockets are from the Voskhod factory - they come in two version one with the plate post and the other with the wire getter post.  Both are excellent and were my #1 6N23P - until I stumbled on to the '74 and '75 Reflektor SWGP Silvers.  They took the throne.
 
They are all excellent tubes with slightly different characteristics.
 
Here was a review I posted comparing them, if you want read about my take on the differences: page 134, post #1999

Cheers to both of you!

I still can't thank you enough for letting me have the pleasure of purchasing these. I don't think I've said "WOW" so much in my life , while listening to tunes. I feel like I'm in church when I put my cans on these days. Lol

Guess that's your wallet on the right 

 
I keep a text file on the desktop of the PC that ultimately feeds the Lyr, noting the tubes, cans, start times, and hours run in a session.  Sessions can end abruptly, as with the 30-min. power outage this morning.  It's more for the tubes, but I figured I'd add cans, since it's trivial to update both.  Fortunately I started that system early on, so only a few of my first pairs are "best guesses" for their first runs through the Lyr.  Since I was pulling them at around 100 hours, I can get in the ball park re: total time used.

 
Lol...or what's left of the wallet.
 
Thanks for the advice. I started using my Mac's 'Notes' app to track tubes burnin time. Actually, using iCloud, for those that use Macs and iOS devices, makes it easy to list tubes, build wish lists, etc and review them from other mobile devices and other computers as it updates in near real-time.

That what it's all about - glad I could share it
 
The HG's are really special

Thanks guys. I am excited about sound development as the tubes burnin.
 
I had a hiccup with Audirvana+ that stopped the app and the music piping to the Lyr. I was away from the setup so did not notice until I came back. A better burnin option seems to be a recommendation by satwilson to use a CD player on a loop for the burnin stage to minimize the possibility of signal interruption.
 
Enjoy the music guys and thanks for all the great advice on this thread.

Don't worry, your tubes were still burning.  As long as the power's on, they're burnin'.
 
I have a playlist in foobar2000 that will play for 2+ weeks

Gosh, I am starting to feel old. My paper and pencil system works fine, but then there is the file cabinet just for tube logs!!! Gotta digitize, plenty of room on the hard drive, thanks Thurston!!!!!

For handling the tubes. Should non-powdered medical gloves be used? Or a sock over the hand?

I use this IsoTek Full System Enhancer CD for part of the burin process - I have it burn't to my music servers and run it from time to time.
 
It will help de-magnetize some of the components (like resistors) that build up over time.
 
It also presents full audio frequency spectrum sweeps and pure white noise.  Worth the $30 bucks.
 

OVERVIEW
A variety of tracks featuring specially developed algorithms, which create a unique set of signals to reduce burn-in time and ‘run-in’ equipment. The disc can also demagnetise audio and audio-visual components.

1. Perfect burn-in disc for all new components.
2. Full system demagnetization.
3. Simple, cost effective solution, which is considered an industry standard.

 
PRODUCT DESCRIPTION 
The Full System Enhancer CD is an intensive ‘workout’ for your audio system. The disc includes specially developed signals to help ‘run-in’ new equipment, as well as demagnetising existing hi-fi components and rejuvenating your entire system.
It is important to exercise an audio system across the full range of frequencies and amplitudes it may encounter in real life, and to this end the tones on this disc have been devised to cover the complete audio band from top to bottom, also ensuring that, for instance, high-amplitude signals are combined with high-speed ones.
In electronic terms, the required signals feature lots of high-speed activity coupled to some high-amplitude excursions. All of these signals have been produced according to strict mathematical criteria, so as to place the greatest stress on the important parts of a system – without, it is important to note, endangering any part of it.

I just got some new vintage Siemens E88CC tubes in Lyr 2.  Sometimes I get microphonic noise when the Lyr 2 is turned on.  But when I turn it off and turn it back on, I no longer get microphonic noise. Is this normal for new tubes getting burned in? It didn't happen when I initially got them, but now it's happening couple of times. 

 

[htr2d2]

  Ok folks here we go, after holding out for a few days on the 75s HGs from Bob, and after a quick exchange over private messaging with him, I have taken the plunge and rolled in the 75 rockets into my Lyr2 a few minutes ago. Here are some photos...fresh out of the oven:

Listening to a few tracks right now - initial impression is amazing sound! Much better than the 72s I had a few minutes earlier. I will have to give them the recommended 50-100 hours burn to let them fully open up, but let's say the journey has started. 

 
Will keep you posted!

Congratulations.
 
Nice photos! They look professional. Off topic but what did you use to take them? Beautiful lighting, too.

This thread is costing me some hard earned cash, first good quality tubes, then a tube coating and maintenance kit, and now the system enhancer, but I still gotta thank you Bob and the rest of you guys

I know it seems like it never ends - but you could maybe go in with a few friends and share the disk.  It only needs to be used every 6 months or so - once your tubes are burnt in.  Or just use music.
 
I'm an insane audio tweeker - I've tried it all...

OK. I admit I am clueless, but I have got to ask. How does playing a CD "demagnetize" a system? Not being a jerk. I really do want to understand.

 

[astark]

Well....I could spend my extra cash on a whole lot worse and I did recently get the wife a new deer rifle.
Got the IsoTek on the way from the United Kingdom as we speak
