Best 845 tube out there?

I'm using a pair of the Shuguang PSVANE 845T's in my Art Audio Carissa for a little over a month now.
I have about 45-50hrs on them.

So far...I find the sound to be superior to either the 845B..or the metal plate variety.( i've only used the latest 845M or C...not real sure about that))

They sound remarkable!..very much like NOS!...I'm not kidding!
I'm VERY impressed!
I've not made any direct comparisons, I only have the memories of hearing NOS RCA's fairly recently.

IMO,The 845T's seem to combine the best of the B's with the best of the M's (without the plate dissipation issue).

Of course my observation has to be taken in the context of my system and my personal musical prefferences.

Thanks for posting, Davvie. Can you describe the differences between the PSVANE and the 845B?

The major difference seems to be that the Psvane is far more extended at the frequency extremes,but at the same time has a far more richer harmonic presentation. Much like the qualities of NOS 845's

In comparison to the others, the 845T, right out of the box, seems brighter. After about 10 hours I began to notice a difference. Compared to the 845B, they seem far more transparent but at the same time much cleaner. Bass tones and pitch definition are improved. String tone seems to be more open and extended even more than the 845M,but at the same time more relaxed and natural sounding.
I always thought the metal plate 845 sounded etched and
unnatural.The 845B seemed to be a good all- round well balanced sound.

The soundstaging qualities are improved as well. Front to back layering and placement of instruments is enhanced more than likely because the sound is more open. Your definitely getting more info without any added brightness,at least once they are sufficiently broken in.

Thanks Davvie. I think I will have to buy myself a set of those tubes now.

Don't forget to return here and update us on your 'post burn in' listening impressions, I'm sure many would be interested !
