"has anyone bought tubes for the Rhea (or anything else) from Upscale Audio???"
Yes, this past fall I bought 5 Telefunken E88CCs for my Symphonic Line pre from "Uncle Kevin." He was extremely informative about what the various 6922 family tube flavors would provide when I spoke with him about options.
And when one tube died within the 90-day warranty period, he replaced it without issue. So count me as a happy camper.
