Will a preamp help in this scenario?

[Scuzi]

I have an Amazon Echo plugged into a Yamaha R-N602 using a 3.5mm-RCA cable. It works, however I’m guessing the input signal is markedly weaker than the other sources, meaning I have to adjust the volume significantly when switching sources. E.g. I’ll be listening to music through the Echo, but when I switch to playing FLAC from the network drive, the volume is too loud, and vice-versa.

If I wanted the volume from the various inputs to be more consistent, would connecting the Echo to a preamp do the job? If that’s the case, would a fairly basic (read cheap) preamp be sufficient without having a negative impact on the sound?

Thanks.

Thank you for the replies. I’ll have a look at the suggested devices.

I have tried Bluetooth but it suffers the same feature. It is also susceptible to noise with noticeably poorer quality.

Is your echo at full volume?

Yes, full volume. I have been caught out by that a few times now!
