Indeed I believe the bottom line runs something like:-
Shit in = shit out.

There is nothing objective or in the slightest bit scientific about claiming one valve sounds better than another.

There is a lot of production spread on mass produced radio valves, and then there are almost no circuits which were ever specific in the demand for one parameter or another,-

(Unless of course you were an OEM like Mullard and nobody else made the valves, transformers and components specified, - eg. Partridge, Gardner, Woden, Parmeko to name some quality names).

Today this impossible because the market for millions of units evaporated in the 1960s, so what you have left is, nothing better than mountains of hearsay.

If you produce millions of valves (in 1960) cheap enough, you can afford to reduce the spread, then farm the sub standard ones to anyone willing to buy them dirt cheap (like some OEMs always will).
That is how they make money, and of course why there is so much demand for stuff from Asia.

As an example:-
Yesterday a simple power cable on my notebook PSU failed.
Most people would go and buy a new PSU.
Because we can, we investigated the cause and it came from sub standard wire from China.
I've had microphone cable from China which didn't even conduct electricity.
They sell that because it means they sell more of it, just like say a badly designed bottom ball joint on the front suspension of a car...

Sub standard stuff is great for the retail market because it enables you to generate failures and to make the customer pay for putting them right.

I don't know of any mass production industry that operates any different, cars, computers, you name it.
It's designed to FAIL, so that you can sell them more at inflated price.

The current fashion 6SN7 marketplace is just another version of the great capitalist waste generation program.

Production rejects are what makes mass production what it is.

The reject rate is usually what makes the difference between good, bad or ugly, ie. like the difference between a Lada an Opel or a Mercedes.

The old adage is;- you can't make a silken purse from a sow's ear.

Finally, not opinion but medical fact.

Women of 55-65 have much more acute hearing than men.
By the time men reach 35, their hearing is already going down the drain.
-10dB at 8khz.
By the time they are at 45 it's -20dB.
At 65 years of age sounds of over 4khz are just lost in the background mush and SN.

And you try to convince me you can hear things which are either masked or inaudible?
That's a joke.
