PSVANE - Let’s Talk All Things about Vacuum Tubes

My sincere apologies, everyone.

Due to an unexpected cold, I wasn’t able to respond in time.

I will be replying to each message individually shortly.

Thank you all for your kind comments and patience.

@audiosaurusrex 

For audio vacuum tubes, the hierarchy of our product line is as follows:
Basic：HIFI、UK
Selected：HORIZON、ART
Premium：WE、ACME

The HORIZON Series is our latest line, featuring a more neutral sound compared to the Art Series and incorporating the latest technologies, such as HPC coating.
The WE Series pays homage to the classic Western Electric sound.
The ACME Series is our true flagship, offering a neutral and well-rounded sound profile.

Currently, the Horizon Series and ACME Series are the only lines sold directly by us on Amazon.
All other series are sold by other distributors.
 

The official warranty policy is consistent, offering a 12-month free replacement.

What no pics?

I have a question.

How do you pronounce Psvane?

Thx in advance....
