Cayin HA-6A Class A KT88/EL34 Tube Headphone Amplifier
Hi all, I'm glad I didn't buy the HA-6A, I'm very happy with my Feliks Euforia which doesn't make any noise, hiss, etc ... just music. My Cayin HA-1A MKII had a faulty power tube, but it still does a little zzzz which changes depending on the position of the impedance selector, I think I will...- IPMano

New tube amp: the Cayin HA-1A MK2
I understand cayin's policy and that's normal, I think that one of the tubes has a problem because it produced strange sounds (cracking, whistling, ...) and as soon as we touched it we heard noise.- IPMano

New tube amp: the Cayin HA-1A MK2
Hi all, I received my EL84 Psvane tubes, the difference is immediate, the bass is much more powerful and especially more parasitic noise, crackles, whistles than I had with one of the original tubes, the new ones are less sensitive to shock, the originals as soon as we touched the amp we heard...- IPMano

no, on the two channel, with the 12au7 original it's the same, when I turn it on the noise is loud after 15-20 sec it decreases I know someone who bought the HA-6A it has the same noise.- IPMano

New tube amp: the Cayin HA-1A MK2
@Andykong There is a snore like 50hz, the lower the impedance selector the less you hear the snoring, this snoring is due to what? there are also sometimes strange sounds (noises) like hissing, if I tap on the amp this noise disappears or reappears, what can it come from? I do not have this...- IPMano

New tube amp: the Cayin HA-1A MK2
I do not think that the choice of the headphone impedance selector on the smallest position hurts the headphones or the amp, I have a T90 of 250ohms and my selector is on the lowest position to not not have that background noise.- IPMano
