12AX7LS – “Overall, amazing, musical, without sounding louder”

Feedback received via email:

“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”

Psvane 12AX7-TII: “fuller body, bass is deeper and punchier, highs are more pristine”

Feedback received from customer on Psvane 12AX7-TII via email:

” I was very happy with the Psvane 12AX7-T compared to the NOS Electrohome 12AX7 which is Canadian 1963 produced tube that closely resembles Amperex Buggle Boy. This NOS tube is quiet like Psvane 12AX7 but the NOS tube is roll off on top and bottom while midrange has that clarity and bite that makes vocals sounds crisp. But prolong listening, it sounds like typical SET amp that accentuate midrange. When switch to Psvane 12AX7-T, it is just as quiet but has fuller body, bass is deeper and punchier, highs are more pristine. This makes orchestra music more complete and musical, satisfying. When I watch movies, I hear more ambiance cue and soundstage is larger. ” – Jimmy P.

A new addition to high end KT88: Cobalt Blue Super Tube (KT88-Z CB)

Sometimes we wonder if there is a limit of high end… apparently for tube producer from Asia, there is no limit yet!

This new custom version KT88-Z CB cobalt blue Super Tube seems have “surpassed the current high end KT88 tube offerings, in instrument separation and frequency extension on both ends”, according to factory in-house comparison to competition.

Order yours now to experience the new limit of ‘high end’…. KT88 doesn’t have to be low resolution as some people perceived!

New feedback! “KT120-Z CB are definitely an upgrade over Tung-Sol… and very reliable”

I had the tested Tung-Sol KT-120. Installed on the Sonic Frontiers for quite a while. I installed these new PSAVANE KT-120 on the same amp hooked up to the top of the line Pathos «  In Control «  pre-amplifier. Speakers were the ProAc Response D20 R ( ribbon tweeter) and later, the new Martin Logan Electro-Motion hybrid electrostatic speakers.

Upon installing & biasing the new tubes on the D20R, I noticed a right away increase in transparency , detail in resolution. It became even more obvious when I upgraded the speaker cables to the new Cardas Cygnus.  Also, an increase in depth very noticeable with either set of cables.

Also with both set of speakers, there was no brightness at all with these new tubes. No forwardness either. Overall, these new KT120-(Z CB)are definitely an upgrade over the Tung-Sol. And so far, they have been very reliable. And they look good too.

Have a good day,

WE274B: “the difference between those and the WEs are night and day”

WE274B replica-1Feedback from customer Albert W. via email:

“Hi Rachel,

Like the previous review on the psvane tube website I would have to second his opinion of these tubes. My previous tubes were a Shuguang 274B but the difference between those and the WEs are night and day. From the first start up, I’ve noticed that the background was much more black. Without a doubt the definition was superior along with the soundstage. The tubes may be pricey but I believe they are worth the extra cost. Thanks. Best Regards,  Albert”

WE274B replica – “this tube is well worth every penny”

WE274B replica-1Feedback received from Thomas L. via email on WE274B replica:

“Hi Rachel,

  I just received my order of the WE274B last night.  I have to say I’m not sure what to expect, but hoping that the sound of my system doesn’t take a bad turn. The rectifier tubes that I had been using are Ken-Rad 5U4G and Amperex GZ34.  The 5U4G has a thicker sound where as the GZ34 seems to a little harder sound, better bass but less musical.

After plugging in the WE274B, without any music playing, my system seems very quiet.  It almost seems my system was not turned on.  When the music starts playing, music just emerged from the sound stage.  The Impression that I keep getting while listen to my system with this tube in my DAC was much better resolution, smooth, and punchier bass.  (Notice I said resolution, not detail.) Soundstage is more spacious and deeper.  Definitely less listening fatigue than when I had the GZ34 or the 5U4G in the DAC.  I have to say this tube is well worth every penny.”

1920’s True Mesh Type 50 Replica now available

Steve 50 amplifier

Instead of typical tech talk about a new tube launch, this time we have a story to tell about the type 50 replica tube’s birth… by Steve Berger, a long time audiophile and music lover resides in NY:

If you cannot wait to finish the whole story and wish to order right away, get to order page here.  

“Foreword by Steve Berger:

In the early 1990s I got a call from Vincent Gallo. He had seen an ad for a Gibson GA-50 guitar amplifier that I was selling.

When I walked into his apartment, performing delivery of the goods, Chet Baker’s “Happy Little Sunbeam” was playing on a system consisting of a Western Electric 91A 300B amplifier and a lone Western 757 speaker mounted on the wall.

I had never experienced such sound before: Chet’s trumpet was right there in the room!

This was my first introduction to directly heated triodes and my life would never be quite the same after that day.

Black Treasure 12AX7-LS: “They are absolutely great”

treasure 12AX7LXFeedback received from Peter in Germany via email:

“These tubes really needs time (120+hr) to grow.  Now, they are absolutely great. The best i’ve ever heard before, period……I’m very happy too with the big sound of the LS-type in my big amp. Even after 72 hours they sounds good, but now, after 120+hours, I’m in heaven. Tonality, detail (!!!) and room are just great. An absolute notably improvement to the Psvane 12AX7. The warm, precise, detailed and big sound fit perfect to my preference.

This new tube-setup let me discover several tones, noises, coherence in my musics I’ve never heard before, incredible!
