I have both the Elroy 300b and Tatsuki 300b along with XLS, mid eighties WE 300b, Psvane WE300b 1:1 and Shunyang WE300B, as well as EH300b, Shunyang Treasure, Genelex Gold Lion reissue 300b.
I have bought the Elrog 300b tubes from the new Elrog owner and let’s say after comparing them to the Tatasuki and the WE 300b’s I bought another pair as these are my new standard. I use the tubes in my Manley Neo Classic 300b Preamplifier. They are a modern 300b and not even based on the original WE design at all. Transient response and slam are beautiful and yes they even maintain just the right amount of euphonics across most genres. I can not say the same about the orig WE 300b’s for sure. I have ~500 hours on the Elrog 300b’s. It was hard to best the Tatasuki 300b. Until the Elrogs they were by far my favorite. They did take a while to finally break in. Not so with the Elrogs they were pretty much perfect from the first power up. h and they look amazing very tall and not at all like a standard 300b bottle.
Oh and they were nearly half the price of the Tatasuki's. I love me a "bargain"
