That's the high-end version, yes. No complaints here, and they stand by their product.
Assuming you're just getting them to "save your sockets" and make rolling the standard Lyr/Lyr 2 tube types easier, you only need one pair. If you're planning on rolling non-standard types (6C8G and/or 6SN7 (Lyr 1 only) that require a much wider adapter, you'd need two pair of socket savers just to get above the level of the top of the Lyr chassis. If all that sounds like gobbledegook, just ignore it and get one pair of savers.
Nah, not gobbledegook at all, I get it. I appreciate your feedback and help. I figured not to go cheap and if I'm going to do it right, do it right the first time!
