Does a lower input RMS level (1vRMS) worsen the performance?

[LJHR]

Hello everyone. Over the past few weeks, I've been very confused by this question.

I have three dongles based on cx31993. For a long time, I used them as dedicated DACs, connecting to my speaker AMP and headphone AMP. Because I think dongles based on cx31993 have average performance, low price, and low heat. The volume can be controlled directly on the computer.
One day, I suddenly discovered that they could only produce 1vrms RMS at max volume. If the lower output voltage significantly reduces the performance of other devices, such as SINAD, dynamic range, distortion, and more, should I replace them all with desktop DACs?

Thanks!

There are two ways in which a 1V signal source can impact performance:

It can limit loudness and can require higher gain settings on your Amp, which usually means more hiss.

If your current setup plays loud enough for you, and without audible hiss, then upgrading to a higher voltage signal source would not increase sound quality.

Thank you very much！！
