I have used the standard ceramics in everything I've built over the past 10 years. Not as much stuff as most folks here, Im sure. But all the recent Bottlehead gear and a couple amps as well as another phono stage. I havent had any problems with any of them yet. But they dont get tube rolled often after I settle on tubes. Im sure the better sockets, are, well, better or atleast more durable in terms of standing up to rolling and maybe the long haul. But with my having no issues, I havent found any reason to replace them or use something more expensive. I guess it's an if it aint broke, dont fix it kinda thing for me.
