Frequently Asked Questions
What makes Amp Ultra Unique vs. The Ultra and Vibelink Amp?
The Amp Ultra is WiiM's all-in-one, integrated solution for simplicity and performance. Compared to other offerings, it features a dual-amplification architecture and a premium DAC, plus advanced streaming features like room correction.

It is the ideal choice if you prioritize a minimalist setup with top-tier features.
