Schiit Freya + tube rolling


I’m really enjoying my freya+, I’d like to get into tube rolling. It comes with 6sN7 but I believe it can host a variety of others. Is anyone having sexy results with aftermarket tubes?

This test compared tubes using using Sagas rather than Freyas, but I thought it was interesting: https://audio-head.com/double-blind-a-b-schiit-shootout-tubes/
thanks y’all !  Keep it comin 
When I want to roll tubes at reasonable cost, I go to Brent Jessee recording, aka, http://www.audiotubes.com. Here is his 6SN7 page: http://www.audiotubes.com/6sn7.htm. Over the years I've gotten RCA greyglass 6V6GT, mil surplus ultra low noise Philips EL84WA, and many others including RCA 6922, etc. You also might benefit from a conversation with Kevin Deal, proprietor of https://www.upscaleaudio.com/pages/about.
I've had great luck with both of these vendors.
