Those Lorenz SEL labelled ones are not the original Lorenz tubes made in Stuttgart, West Germany. I wouldn't spend my money on them if I were you.

Selling my Lyr. These were purchased from tubemonger and have about 100 hours on them. The brown Lorenz label and Made in Germany are faint but readable. Aussie Head-Fiers get priority. PM me if you're interested.
Thanks!
If you don't mind explaining to me, how did you know that? I'm pretty new to tubes

Can anyone point me in the right direction as to a tube that would really lift a veil as compared to the tubes I've tried. I mean when I went from the JJ's to schiits GE's I thought they were pretty great, I also thought the Sylvania's were good too but I figure that it just because I haven't tried other higher tier tubes.
I've bought a couple pairs from musculitohifi, and they both tested NOS and were genuine (correct and proper date/code etching, unique Siemens riser crease, etc.) Sonically, they sounded identical to other CCa's I've had. I don't believe the newish boxes were genuine issue, but they were authentic Siemens & Halske boxes (or at least seemed to be). He does a fair amount of volume, so it's virtually impossible to not collect any negative feedback. A lost package, is generally enough to cause some to give negative feedback. On affiliation or alliance - just sharing my experiences, which overall were good.
......There is also something called a getter: while I can't say whether getters affect sound quality, D-shaped getters are somewhat more expensive than O-shaped or halo getters because they are older and rarer.
Hi songmic, first of all, your summary is FANTASTIC!
BRAVO to you for your efforts!
As for the getter, IMHO, the getter itself does not affect the sound quality.
However, it can be used as an accurate gauge of the age of the tube and hence the sound quality.
The oldest vacuum tubes had the D-shaped getters.
This applies not just to the 6DJ8 family but also to other tubes.
This can be considered to be a General rule to vacuum tubes.
Another general rule to vacuum tubes is that the oldest ones (within each brand and line) tend to sound better than the newer ones.
So that is why many tube rollers make the statement that D-Getter tubes sound the best!
I have done this comparison myself and I find that it is very true in general.
E.g., the D-getter tubes in the 6DJ8 family have a 3D effect which is less pronounced than their O-getter siblings within the same family.
Too many PMs to respond to individually. I've now listed the Stuttgarts in the FS section. Please refer to responses there.

Looking for a tube:
Primarily concerned with: Resolution, Imaging, Soundstage
What would you recommend?
Right now I'm using a Mullard CV2493 in the front stage and using Telefunken PCC88 tubes for the L and R channel with a Tung Sol 5Y3GT rectifier. It sounds very nice but you know how this audio thing works... always chasing something better! Recommend me the best tube that you can find! I know the Lorenz is awesome but you can't find them anywhere...
Thanks in advance!
I second that - good job Songmic! I third what Lord Soth said re: getter. For the sake of clarity and reinforcing tube facts, the 'getter' is actually the reflective 'flash' usually inside the top of the tube (their are some exceptions to the placement depending on the tube type/design - an example would be the RCA clear tops). the 'o' or 'd' is often referred to as the 'getterer' by old timers. It's only useful period is during the construction of the tube, after a vacuum is applied to the tube and a charge is applied to 'flash' the minerals to the inside of the tube. After flashing, the getterer serves no other purpose (other than as Lord Soth noted, in helping us identify tubes of a better 'vintage'). Older tubes tend to be better because of 1) liberal use of rare earth minerals that are either not used today, or are used more sparingly or more diluted, and 2) construction techniques that seem to not have been handed down, are lost, or are too time consuming to be with recreating.
