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?

Curious to hear from Psvane WE 845 owners how their tubes are holding up now that they have some usage?
Thanks
Keng,

Thanks.
We actually refunded 100% less shipping to our customer.
On the other hand, we have yet to receive our money in full from the distributor but that is our problem. :)

On another note, we are waiting to receive some new Shuguang 845C-1 and our understanding is they are rated at 100W so we are excited.
Are there any updates regarding the performance of the Psvane WE845 from people who use them? Thinking of purchasing them.
I need to correct an earlier post where I recommended the 845T tubes. I've been using various 845 types for at least 12 years and these are the only ones that ever failed -- two of them. Silver lining is that I was "forced" to use my back-up metal plate 845C (which I once said sounded "metallic") and find I like them so much better than the 845T types that I have put off replacing them. Sometimes things do work out :-)
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
