It has been brought to attention recently that one AudiogoN member attempts to resell his Shuguang Treasure tubes by claiming they were purchased from Grant Fidelity as Grade A quality. He even further lied to a potential buyer that his tubes come in packages same as how Grant Fidelity identify Grade A tubes. However he wasn’t able to provide pictures as proof.

We have requested the seller to provide his purchase receipt from us before he claims that his tubes were from Grant Fidelity, immediately this particular seller removed his wording of tubes bought from Grant Fidelity as Grade A.

We strongly suggest consumers to use good judgement when purchasing tubes from individual sellers. If you have found anyone pretending to sell tubes from other source as from Grant Fidelity, please report to us immediately.

Please also take time to read our Test Method and Quality Control section to understand tube quality grade and protect your own interest before any purchase.

We also have compiled a list of unauthorized tube sellers – their selling status has been confirmed by factory as ‘unauthorized’ and their tubes were not purchased from factory directly.
