@dentdog et al How has your tube rolling gone? Which of the Sylvania chrome domes did you try? Came across a head-fi thread that says you have to be careful with the GTA and GTB models - https://www.head-fi.org/threads/the-6sn7-identification-guide.209782/. Not sure what to make of it re the Chardonnay, which I have on order. Also note in one post he says the term chrome dome is incorrectly used for some models now. There are also some 6SN7 reviews/shoot-outs posted (see below). Looking around the Grant Fidelity/Psvane site, they found the Shuguang WE version and the Psvane one’s to be very close. One pays more for the better versions partly because of the warranty but also because they are found to be the best of the best, upper 10%. Same type of thing that Upscale Audio does. The ones costing less at eBay or Chinese store sites are made out to be part of the rest. Don’t know if the latter is true, as it may be a matter of luck of the draw, or maybe the stores are just not getting the cream of the crop. But then there’s the WE Plus version with the carbon fiber coating that’s been lauded. Lots of choices, and some not necessarily dear.
