Well, I've come full circle and purchasing the Sophia SET Princess Carbon Plate. I had placed an order for the EML 300B but Tube Audio Store didn't have stock. So reluctantly (explanation coming...), I tried ordering from the only other US dealer; George Lenz at TubesUSA. I soon gave up on that. He has these extra fees/charges (PayPal higher then 3%, packing material costs,..) and he's very evasive with any questions. It's no wonder he has stock - no one buys from him. Arrogant, rude. Don't buy from TubesUSA. That forced me to rethink which tube to use, but after speaking with my amps dealer, who felt the Sophia was better then the EML, I took his advice.
Charles1dad: I was being sarcastic with Tvad.
Rodman99999: Too much.
