300B tube recommendation for SET amp?

Vu, of Deja Vu Audio, recently sent me a pair of his custom 300b monos with his best rare vintage transformers. He chose EH Gold Grid for that amp. My Art Audio sounds best with the Sophia Princess and with my Welborne DRD I like the EH. Point is in some circuits one brand may sound better than another and of course, it's all about your own individual taste. I will add this, the WE sounds fantastic in all of mine.

Hi Larryi,
The trannies were the Acrosound, not sure of model #, and the amp was pushpull. Vu's amps have a beautiful sound to them. He told me he does make single ended but the price jumps to 20k or more because it's much harder to make a transformer for SE so they are rarer and much more $. I wish I could of tried the WE in them but I only have 1 pair.
The first time I spoke with Vu, I told him I had Apogee Duetta Sigs and he offered to send me a one of his 2a3 pushpulls. I thought this was a bad idea but I had some other speakers I could try them on also. Well the 2a3/Apogee combo put out some of the nicest music I've ever heard within of course certain spl's.
