I'm currently running simple set up of Yamaha HS5's through a DOUK Audio Pre-Amp (Link below). I've just bought a second had pro-ject debut 3 to add to the set up, and the volume is very low even when everything turned to the max, which I'm assuming is due to the pre amp not having enough power to convert the sound enough.

Please can someone give me some advice on whether there's an easy fix for this, or whether I will need to invest in a more power pre amp/amp?
