PSVANE EL34-Z
I bought these tubes based on reviews and ...., at first after the first connection I was disappointed, the sound was quite rich, but only in the upper range, there was no bass at all, overall no dynamics, such a listening experience from transistors, but .... today they have been played for about 46 hours and the sound? It's great, the tubes have settled in, they have gained really beautiful dynamics, the bass line is not oversized, it is exactly as it should be, the mids are wonderfully rich, the highs are brilliant, I listened to the album Corvengence by Maila on the Cayin CS 88A amplifier and I really enjoyed it. All sound bands are fully occupied, every detail is wonderfully audible, so from the initial disappointment there is really a lot of enthusiasm. The tubes are really the tip of the iceberg from PSVANE, I haven't heard anything better yet and I have about 10 different sets at home. So whoever buys them should put up with the initial not-so-pleasing sound, it will get better over time after the burn-in, it really takes time. I believe that after 100 hours of playing it will sound excellent. Don't worry about it, I can really recommend it :)

Review: PSVANE EL34-Z
A Truly Audiophile Experience.

I bought these tubes on a recommendation and with some slight hesitation, but my expectations were absolutely exceeded. They sound fantastic, and after only a few hours of burn-in, the sound started to open up and improve. After about 30 hours, the sound is completely stable and amazing.

Sound Characteristics:
Unlike other EL34 tubes I've tried, the PSVANE EL34-Z has an unusually transparent and precise sound. They don't impose their own character on the music but rather reveal details I hadn't heard before. The bass is deep and controlled, the mids are beautifully clear, and the highs are delicate and accurate.

Conclusion:
If you're looking for an upgrade for your amplifier, you definitely won't go wrong with the PSVANE EL34-Z. They are some of the best tubes on the market.
