User Experiences on Sophia Electric Aqua II 274B Rectifier Tubes

Hello Sue,

Thank you. I'm also going to order another Aqua II 274B as a backup. I never want to be without that amazing sound quality.

Best wishes,


Hello Folks,

Just a quick note to say that this new tube is absolutely sensational. I was happy with the first Aqua, but version two is substantially better and I am a very happy customer. Thank you.

Best wishes,


Greetings Richard!

Upon receiving your recommendation some month backs regarding the improved 274-B Aqua II, I finally found the “go ahead” funds. My reaction after two nights of enchantment? DIVA! 🎉

This has proved to be a very satisfying purchase. Using the Aqua II inside 6SL7 Battery biased phono preamp fed by a Hana MH cart. All Shindo Laboratory electronics via Magnepan LRS or HiFiMAN HE-6 headphones to speaker taps. I’m really diggin’ this tube! 

Kind regards,
