Feedback from a recent customer Denis who purchased Psvane 12AU7-TII (GF grade A):
“Bonjour at Grant Fidelity
My Psvane 12Au7 are in, and as soon as i put them in my Italian hi fi preamplifier i loved them immediately, i mean not the tube themself but the music coming out of them.
i own NOS Amperex 12AU7 that i found amazing but lacking top end absolute clarity and transparancy, and i also tried the new Northen Electric 12AU7 that a friend borrowed to me , but with them i feel an evident tonal inacurracy in the mid-range, especially in the piano and vocal.
The psvanes beats them a lot!! better musicality and clarity/definition
i am very happy with my purchase
Best regards
Denis”
