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!

 

Treasure 6SN7-SE Globe – TNT Audio review published

Treasure 6SN7SE pair in foamHere is what reviewer Mark Wheeler said about these globe shaped tubes:

“If your 6SN7’s are on show and there is space for them, there is every reason, sonic and aesthetic, to install the Shuguang Globe 6SN7-SE. In a high resolution system, especially of the low-to-no negative-feedback persuasion, these Shuguang globe 6SN7-SE bottles are the state of the new-wave-of-valve-production (NWOVP). So far Shuguang have not put a foot wrong and we can hope they continue to innovate new versions of those classic valves we all love.” Read the full review here.

Treasure KT120-Z: “I could live with this tube for a long time.”… “it is a steal”.

treasure KT120 quad boxIt is official! The Treasure KT120-Z has been reviewed by Stereotimes and here is what the reviewer said – “I could live with this tube for a long time.”… “It is a steal!”

The review was done with a high end Ayon integrated tube amp which uses KT88 and KT120 type tubes.

“On various cuts the Shuguang Treasure KT-120 tubes sounded more interconnected across the entire frequency spectrum. The Ayon Audio tubes seemed less controlled and transparent by comparison almost lacking in headroom and while the Shuguang Treasure KT-120 tubes were more illuminated in the midrange and high frequencies displaying a more live sound. I clearly preferred Shuguangs it to the Ayons.

Over the course of this review, some cable and system grounding changes were evaluated and based on the transparency of the Shuguang Treasure KT-120 tube, it was always easy to hear even the subtle differences each system change displayed.  You know what I really like about this tube in this application?  It’s the reliability.  I’ve power cycled my Ayon Audio Triton MKIII many times over the course of this review and have never once had a tube failure but I have almost a dozen tube failures with the stock tube.

Conclusion

After hearing the Shuguang Treasure KT-120 tube I can declare my search for the best KT-88/120 tube is over.  I have no desire to reinstall the Ayon Audio KT-88SX tubes if that tells you something.  I wouldn’t hesitate to recommend these tubes and at the price of $349 a quad they’re a steal. ” Read full review here.

New ‘affordable and most reliable’ rectifier tube added – Psvane HiFi 5U4G

psvane 5U4G single - largeThis Psvane HiFi series 5U4G is claimed by factory as ‘the most reliable and affordable rectifier tube ever made’. It is a replica of NOS Phico black plate 5U4G rectifier, but maintained a very friendly price tag.

Rectifier tube is probably the most ‘consumed’ tube on a tube rectified amplifier. It will need to be replaced more frequently than a power tube over time, so reliability and price are both sensitive factors for tube amp owners. Now Psvane is offering a new option for tube amp owners who are not only cost conscious, but also sound driven. Click here to order yours.

“Hi Rachel,

I just thought I would drop you a note having put the 6SL7-Z tubes into my monobloc amps.

The only word I can think of to use is WOW!

I have never heard bass like that from ANY amp, never mind a valve amp. What a difference it has made to the music.”
