I was included in the pre-release review of this new line of tubes by Psvane and I'm super impressed with my initial testing of the EL34-AT tubes I was sent. Punchy, detailed and has a sound that reminds me of a KT120. They also sent me some KT88, 300B and 12AX7 tubes to review, which I haven't gotten to yet. Linked is a video on my impressions of their EL34-AT.

Here are the other tubes they plan to release this summer:
