Amperex tubes questions

Hi,
I am about upgrading my SFL-2 tubes and got an offer of Amperex :
1. 6DJ8, orange labeled, made in holland, PQ, A-getter, non-gold pin.
2. 7308, white labeled, made in USA, no "PQ" marking (no shield mark too), gold pin.

Does anyone knows differnces between those tubes, sonically, lower noise, etc? Thru my search on the internet, I rarely found the information regarding the white labeled but no PQ mark amperex.
Thanks so much
Regards,

I have a pair of Amperex 7308 USN-CEP's that I sometimes use in my Audioprism Mantissa preamp...very nice from top to bottom!

The 7308's are for someone not wanting to much of a good thing IMO...if your looking for lots of color, it's not there.
