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

great valves but one went noisy after a week.

Très bons tubes. Sonorité parfaite.

Beste upgrade

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!

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
