Best 845 tube out there?


I am running a pair of Cary CAD-211AE monoblocks with the standard no-name Chinese tubes shipped by Cary. Whilst I am happy with the sound, I think I should buy a pair of 845's to keep as backup in case something happens to these tubes.

Because I will need to buy FOUR of them, this rules out any tube that sells for stupid money (e.g. vintage RCA 845 tubes).

The only current production 845's I am aware of are:

- Shuguang 845 "standard"
- Shuguang 845B
- Shuguang 845C
- Shuguang PSVANE 845
- KR Audio 845

I have found reviews of the Shuguang 845B and 845C, but there is virtually no information out there on the new Shuguang "psvane" 845. Has anybody heard this valve, and is it a noticable improvement over the 845B and C? Also, what do people think of the KR?

I took the plunge about 3 months ago and purchased a pair of WE845
replica's from Grant Fidelity.
Excellent tube. Much better then the Shuguang 845B tubes I had been useing
Read Tcscata's 3/13/14 review which is spot on.
Enjoy

If you don't mind to share, what amp and speakers do you use?

Of course your source and pre are extremely important as well as wires room,power, anti vibration tweeks and on and on and on
Goldeneraguy, I have Melody m845 mono amps and Meadowlark Shearwater HotRod speakers.
i have about 100 hrs on my 2 matched pairs of Psvane WE 845s. they are getting better every day. much better soundstage then the Shuguangs they replaced.better vocal realism…better PRAT…better piano reality.i had one of the designers of the amps i have..Chalice Audio 'Grail' SET monoblocks over saturady night and he could not believe how great the tubes sounded…i will be replacing my 300bs in the next month and have not decided whether to go with the Psvane WE s or the Elrogs..is there synergy among tubes..?..
