SA30 volume issues

Hello all, recently purchased an Arcam SA30 to power my focal aria 926s. First few days it sounded great at lower volumes, loud and clear. Now I have to double the volume knob to get the same output. Curious as if any one else has had a similar issue, and if there was a resolution to it.

Thanks!

It may be helpful, if you describe whole path of the sound. Input may play at least as important role as an output.

In my case there is no problem with sound incoming from Tidal network, CD and phono inputs. It sound loud and clear. But level of sound from TV connected through the game input with optical cable is dramatically lower. To understand talking I have to pump up the volume at least to 30. It still sounds clear, but definitely something is wrong. I don’t worry about it, becouse I didn’t buy this amp to watch movies but maybe it’s similar reason.
