I have never had the opportunity to listen to your amp but based on reviews it seems that your Hegel leans to the analytical side rather than warmth. If you are interested in making a moderate change towards a warmer sound, I would recommend looking at a different amp altogether. Something from Pass Labs perhaps. You would lose some damping in the bass, but their amps still provide ample bass. If you are looking for a subtle speaker change in the direction of more warmth, I would recommend looking at the new Vandersteen 2Ce Signature III ($3,279). I wish you the best of luck in your journey. https://www.vandersteen.com/products/model-2ce-signature-iii
