Has anyone bought the Psvane Acme 300B Vacuum Tube?

Based on my extensive research, and not having heard in my amp. Taks generally have rep of being on more romantic side, I've seen rare failures. EML, more on cool side, never seen a single failure,  Elrog, seen perception of sound quality all over the place, I tend to believe bit more on romantic side, many failures with previous iterations, haven't seen a documented failure of latest iteration.  Acme, lean just a bit warm of neutral, rare failures, mostly seen in some Line Magnetic amps.

Keep in mind these are generalities, YMMV. Above from observations over many years in any number of forums and reviews. My choice for 300B were based off Western Electric and EML for reliability and durability, Elrog, Taks and Acme for richer sound. I'd expect the Linlai Elites are another top contender.

And then there’s this about the Tak from "The Quick and Dirty 300B Shootout" in Stereotimes, which included the Elrog but not the EML:

This was definitely a crowd favourite and elicited plenty of excited superlatives. The Takatsuki is a very clear and open tube with the widest and deepest soundstage. The top end has incredible amounts of air, which created the most realistic acoustic space among the tubes on test here. I found the staging to be slightly forward, with noticeable midrange projection, contrary to the findings of one of the participants who felt that it had recessed soundstaging.

It had less tonal density and heft compared to the Elrog, and careful matching is required to avoid excessive brightness. Otherwise, it was the clear leader in terms of detail retrieval, imaging and soundstage precision. The crowd begged for the Valvo Heerlen 12AX7 to be put in place of the Telefunken (more details below), but I politely declined to maintain a consistent test base for our shootout.

Here are the comments from the other participants:

"Big soundstage, airy, good extension of highs and lows, slightly colored compared to elrog. Suitable for vocals and recitals."

"Open, lit, detailed. Excellent soundstage and so holographic sounding."

"Voicing "behind" the speakers, incredible microdetail and filled out the space. Extremely holographic, clean, and refined. the Takatsuki opened up the sound and removed the ANJ flavouring."

By no means definitive but more in line with my experience vis a vis the open top end and resolution. FWIW.

@blisshifi , So I went and inserted the EML 300B XLS back into my amp, just to check the sound after putting them away for 8 mos. I have to say, you are correct about the brightness, even slight edginess on top. Interesting that this is because of being under-driven at 60mA in my amp. I also noticed how much more robust they are through the whole spectrum, especially the bass and lower midrange. I think this bottom robustness is what I was recalling as romantic. The Taks have a gentleness that is nonetheless quite resolving. And because they are more electrically "correct" in my circuit, they have a rightness of sound that gives greater depth and precision to the presentation. At least that’s my interpretation, and it’s what I was hearing as "more resolving." I can also understand how this aspect could be heard as more romantic, as you say. Anyway, just wanted to clear this up. I appreciate your knowledge and insight.

@wrm57 Thanks for your report back on the EML - I would agree with your assessment and understand what you mean by the Taks being more resolving. Sometimes there is just more there in the midrange, even if it means being more relaxed at the frequency extremes!

Good comments! These premium tier 300bs are all excellent In my experience. Yet, each will match better with some amplifiers/circuits than others. Very individualistic process.
