PSVANE Horizon Series 12AX7-AT / ECC83 Vacuum Tube Preamp Tubes Amplifier Matched Pair (2 PACK)

I've been tube rolling my ProJect Phono preamp for a while now. I love it, but wanted to experiment with different tubes. I was wondering if I could hear much difference between tubes, and if so, did it really matter? Yes and YES! I've been down the Vintage Used, NOS, New Issue roads, and most were different, but mainly just different flavors of "That's Nice." Then I hit on the 12AX7 Horizons. Boom~! The sound jumped and everything I heard was just locked into place with a depth the others didn't have. I am an audio professional and I am picky enough to drive other people nuts at times. That's what I get paid for. Of course, everybody's ears different, but if you are searching for a unique 12AX7 sound, I'd suggest that you try these. Have Fun!

So far so good... With aesthetix Janus.

I am not a tube expert, I don’t “roll” a lot. I had one channel on my amp start being weaker sounding and looked on Amazon for a well rated solution. I can say, I am quite satisfied with the sound after replacing the originals. Thank you!

I actually had a totally different purpose for these tubes…I installed them in my Yaqin MS-23B phono stage. I absolutely hated them….way too bright and made records unlistenable. I then decided to try something…I swapped the vintage Tungsram 12AX7s out of my main amp, a Yaqin MC-13S, and put these Psvanes in their place, and the Tungsrams went into the phono stage. Bingo! These tubes, coupled with a pair of 1950s RCA black plate 12AU7 and a quad of Psvane EL34-UK, work well in my amp, the Psvanes add detail that the amp never had before, without being brash. My system sounds better than ever. I may try a quad of the Horizon EL34s to see if I can take my system to the next level. Great job, Psvane!!!

Great sound!

Work great in my tube amp! Put the supply Chinese tubes to shame. Was worried about overdriving amp but came out like crystal.

Some of the best modern tubes in their price range!

I bought these to replace the vacuum tubes that came with my amplifier. The ones that came with my amplifier were also made by Pscane, but they were the Art series tubes instead of the Horizon series tubes. These new Horizons were supposed to be better, but they were a bit harsh and thin sounding, so I removed them and put the original tubes back in. It sounds much better now.

Très bons tubes. Sonorité parfaite.

Beste upgrade

great valves but one went noisy after a week.

Ottime! Tra le varie 12ax7 di nuova produzione provate queste sono notevolmente le migliori, le adoro! Montate sul Pre Valvolare Aiyima T20 e sostituiti tutti i 5 OpAmp con i Muses02, sublime!!! Appena acquistata altra coppia :D Le consiglio per ascolto audiofilo. Saluti, Manuel

Buenas válvulas
