Durability is another important aspect I look for. A VU meter should withstand regular use without compromising performance. I pay attention to the materials used in the construction of the meter, as this can indicate its longevity.

Price Range

Price is an essential factor in my decision-making process. I found that VU meters come in various price ranges, depending on features and build quality. Setting a budget helps me narrow down my options without sacrificing quality.

Final Thoughts

In my search for the perfect VU meter for my audio amplifier, I realized that understanding my specific needs and preferences was crucial.
