How important is it for you to attain a holographic image?

I’m wondering how many A’goners consider a holographic image a must for them to enjoy their systems?  Also, how many achieve this effect on a majority of recordings?
Is good soundstaging enough, or must a three dimensional image be attained in all cases.  Indeed, is it possible to always achieve it?

The NOS lasted longer than any tubes I ever had, so there is something to be said for quality control.

How long these new tubes last remains to be seen.

Quite a price increase on the NOS 12AU7’s since I bought them less than a year ago.

This is a description from the Brent Jesse catalog of what I bought:



MATCHED PAIRS 12AU7/ECC82 Telefunken smooth plate, diamond mark, VERY RARE! 

New Old Stock in white box or original boxes. These wonderful vintage tubes are vanishing at an alarming rate. A fantastic, long-lived tube with unequalled sound quality. These are a mix of Artisan, or Mazda labels, some are blank industrial stock, but are Telefunken made diamond mark tubes. These are hand selected and matched to within 2-3 percent transconductance. The cream of the crop, better get some now! CLIENT COMMENTS: "The CD player received two Sylvania labeled Mullard 5AR4s plus two matched pairs of 12AU7 Telefunkens.� We started listening after 30 minutes of tube warm up, and we stopped 2 CD's later after saying WOW many times or even laughing since the improvement was almost unbelieveble. Thanks! W. R."�

$200.00 per pair

In Stock

Newbee, "All" of the tubes I mentioned were Telefunken; they were NOS and brand new tubes, that had identical numbers.

There is a thread here where knowledgeable people discussed this very same thing extensively; comparing NOS tubes, to identical brand new tubes; maybe it could be looked up. I don’t remember all of the conclusions they came to, but from what I can recall the difference was one of quality as opposed to sonics.

I bought the brand new tubes, and I was delighted, now I'm buying some more.  Since quality is a long term thing, that remains to be seen.
