Mullard CV4004


Hi,
I'm thinking upgrade de stock 12AX7 of my Primaluna Two for two Mullards CV4004. I would like to know opinions about these tubes.

Regards,

...and don't forget the NP GrooveTube 12AX7M, an intended duplicate of a Mullard ECC83. They sure sound good in the frontend of my poweramps. Probably they'll be less expensive than the old ones recommended above.
