Those EML 45's range in price from ~ $500-700 a pair!! Not saying if they are or aren't worth it...but that's a lot of coin. 2A3 and 300B are even more! 
The Psvane and Shuguang are more affordable (but still far from inexpensive).
Hopefully, Vinnie will be able to get some and let us hear for ourselves.

All,
I have EML 2A3 mesh plate, and EML 300B. Some 45's, some SV811 and SV572's, a pair of 205-D's (I think Psvane), a
pair of SR-71A's, and a few others. I'll be getting more.
By the end of this month, I'll start the road tour of tubes to LIO DHT PRE customers who want to try, and then they can
pass on to the new LIO DHT PRE customer. We'll get a list going in a few weeks.
Right now I need to stay focused on getting orders out!
Vinnie
