Latest Psvane WE300B-Plus Tubes - Any Feedback?


Hey tube heads, any sound quality feedback, comments, or comparisons on the newest version of the Psvane's WE300B, known as the WE300B Plus? I think it came out in fall, but I can't seem to find any reviews or anything on these newer tubes.

I would love to know how they compare sonically to their Psvane WE300B standard version, or the EML 300b-XLS, or the Sophia Carbon Princess tubes, or any other higher level 300b out there (Elrog, true WE, Tak, etc.).

Thanks!

On the recommendation of Israel Blume at Coincident, I upgraded my Shuguang Black Bottle 300Bs to the Psvane Acme Supreme 300Bs for use in my Frankenstein monoblocks a few months ago.  It’s the best 300B I’ve ever heard.  Out of the box they were superior to the Sophia Electric Royal Princess.  Unfortunately the Princesses never had a chance to break in because they failed in the Frankensteins after about 2 weeks.  If you have Frankensteins don’t put Sophia Electric tubes in it.  Anyway, the Acme Supremes are dead quiet, with the most refined treble I have ever experienced in my system.  Midrange is spot-on, not overly projected or prominent and not recessed.  Detailed and colorful, much more so than the Black Bottle Shuguangs which are great sounding and reliable, but totally outclassed by the Acme Supreme which they should be at the price.  Before break in the bass sounds a bit light, but after about 2-4 weeks that goes away and the bass comes on like a ton of bricks, but in a good way.  Excellent balance from top to bottom, but for me the high frequency reproduction was the real ear-opener.  I pre-ordered a pair of the new WE 300B’s so I’ll be able to compare the two.  Western Electric has their work cut out for them.  The Acme Supreme is as good as a 300B needs to be.  I haven’t heard the Takatsuki, but it’s $1500 just like the new WE.  I got my Acme Supremes for $1000 but they might be a little more expensive now. I’ll compare it to the WE, but I just might be done with 300B upgrades.  They’re good.  IB was right again.

I had been using Acme 300B for 10 months with satisfaction.

Since I have a vintage WE300B made in 1940’s, I had done comparison between them.

My conclusion is vintage WE300B has slightly more tight bass and wider soundstage but the difference is not big.

Acme 300B sounds slightly sweeter than vintage WE300B

if you are listening though an output transformer, you are comparing artifacts that are not music. A great amp has no output transformer to muddy the sound. If you use a resistor type attenuator, not a  TVC or LED, you are listening to distortion. An upgrade before  expensive tubes would be those two.. so just grab a JJ300B, forget the WE types, and be more concerned which performer of the Bach Solo cello performances you prefer ..or which singers you prefer on Decca of a Bellini opera. You do listen to music, don't you?
can't say anything about the WE 300B, but the WE KT88s are excellent. they are my favorite KT88 now.
very organic sounding.
