Thanks. According to the GF website the Linlai tubes are made by Psvane "defectors"
845 Tubes
The Grant Fidelity website lists Psvane & Treasure "special edition" 845s , they have larger bottles and black coating. Has anyone tried either of these and can offer impressions? Also, they are now carrying 845s by prior Psvane personnel manufacturing under the brand Linlai. Has anyone had any experience with the brand - sound, reliability, etc?
