2 preamps connected

I would have thought you could use the Eversolo as a source component into your preamp, surely the Eversolo must have an output that bypasses its preamp?

Thank you, I was just finding there is a beta firmware update that fixes this, should have the full update soon I would think.

You need to find what the unity gain setting is on the EverSolo.  It’s frequently setting the volume on it to the max but you should verify.
