“Hi Rachel,
I received the 12AX7LS super tubes and their performance is super!
Put the new tubes in and turn on, first 10 mins, comparing to Psvane 12AX7-TII…the new super tube has lower noise floor, sound is more dense and transparent, bass is deeper and better bass layering. Sound is richer and much more transparent.
I’m playing internet FM radio and it is finally making music now. Before that, I can hear it is digital and an inferior sound, but not anymore. I’m less critical of my internet FM radio through streamer and enjoying it. Vocals is more lifelike. No regrets buying this super tubes, high value and performance for the price paid. After playing 45mins, details are more resolved and soundstage is deeper. Seems to have better air around instruments. Overall, amazing, musical, without sounding louder. – J Pang”
