Default cryod 6922s

Hi all. Just got a pair of both the JJ and Philips Jan cryod 6922s in a few days ago and wow, they are really great sounding.

Will report later, probably in January, on which is the best sounding, the JJs or Philips Jan as I need more time for testing/listening.

To all, the best Christmas ever.

I have a 6922. How are they? Any good uses in music as far as anybody is concerned?

It's pretty much a 6DJ8 / ECC88 / 6N24P. SQ version IIRC.

Hi,

Colt45, forget the 6N24P...It's the 6N23P you mean.

BTW, what's the point in having NOS 6922s cryoed?
I mean once they're, say, 15 to 20 years old shouldn't they have settled by then?

Anyone else having experience with cryoed tubes?

Cheers,

Default cryod

They are absolutely exceptional sounding.

JJs are much better sounding than the 6dj8 counterparts.

Cryod pair is extemely good for audio. Inner detail makes me drooooool and hard to sleep at night.

The crystaline structure changes with cryoing, as an engineer from a Chicago instrument company told me some time back, FD. He said he actually uses an electron microscope as they use the technique when manufacturing portions of their test instruments.
