Hi Jcarcopo,
I had my Elrogs replaced twice under warranty. I had the early version of this tube and apparently my amplifier ran them too hard. Your Art Audio amplifier could be a better match. The company has new ownership and reportedly has solved the problem with these tubes. I'm hesitant to step back in and besides I'm just very happy with the EML XLS which is very stout and a wonderful fit with my amplifier. In my opinion you currently have two superb sounding tubes. I hope the Elrog proves reliable for you.
