Audio note 300b tube upgrade suggestions. Hello all. Thinking about upgrading the tubes in my Audio Note P4 monoblocks. I need 4 tubes. I have not heard other tubes other than the JJ’s that are in them. The new Audio Note 4300e's are too expensive. Spending $200 to $300 per tube would be fine. I have AN E SPE HE speakers.
