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?

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

Orpheus10

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.

"Serendipity", there is an interesting word. It's so unique that the definition is insufficient; therefore, I will illustrate serendipity.

There is a problem with my sound-stage; the right channel is louder than the left. At first I thought it was the equipment, after a lot of troubleshooting, I discovered that wasn't the problem.

The left side of my listening room is composed of a huge sliding glass door to the patio; that was the problem, a glass wall is bad news. That wasn't the only problem with that glass wall.

The sliding glass door is single pane glass, (no good for the winter) and I want double pane glass. For reasons I have yet to understand, contractors can't replace the door.

I was listening to music, and at the same time, I could feel the winter chill coming right through that huge single pane door; unpleasant, and bad for the heating bill, something had to be done.

I went to Home Depot, bought some foam insulation, came back and taped it all over the door. Now, I can't get to the patio, but who needs a patio in the winter.

Covering that huge door with insulation was work; time to settle back in the sweet spot and do some serious listening. Is it my imagination, or does my sound-stage sound balanced. Wow! I can't believe it; that insulation over the glass door corrected the channel imbalance.

Now that's "Serendipity".
