I’ve tried a large number of 300Bs over the years and the Psvane ACME were my favorite, even over the Elrog and EML 300B-XLS (which were more dynamic and tipped up just slightly) and Takatsuki (which are a tad more romantic and less resolving). I know the ACME has been on the market left due to some of the leads moving over to Linlai. The Linlai Elite line is apparently also very good, but I do not have first hand experience with them.
Has anyone bought the Psvane Acme 300B Vacuum Tube?
These are on my radar but I really know little of them. I had contact once with a fella that re-tubed his VAC Renaissance 70/70 amp with them and said they made a big difference in a good way. It would take about $4K to re-tube my amp with these. I am not in a hurry, just doing research. I can have VAC re-tube it for less than half of this. I think tubes will last a very long time in my amp, especially after I get the MK III upgrade on this amp when I take it to VAC this October. I can also get Gold Lion PX300B tubes for half of this, any one use those? I've had this amp a long time, I plan on keeping it until the grave so I want to do this right their first time even if I have to be patient and wait to afford a re tube. I am retired so disposable income is vastly reduced. I am just thankful i have so many fine audio pieces to enjoy now that I bought many years ago when I could.

@wrm57 I would say that the tone of the EML 300B-XLS is largely dependent on how much they are overdriven. Most 300Bs are supposed to be have a plate voltage at around 60mA, but the EML 300B-XLS requires between 90-110mA to sound its best if I remember correctly. I was able to do this when I used Cary 805AE monoblocks a few years ago and the EML were very close to the ACME. But in other amps where increasing the plate voltage was not an option, the 300B-XLS tends to tip up and not bloom the way you mention. That said, I’m unsure how the Taks were more resolving, I’d never felt that across the 3-4 amps rolled my 300Bs around with. Perhaps it is system dependent as you say!
