I used to have a set up just like yours except different CD player, I tried different ICs. and speaker cables but nothing helps the Thiels current can drop very low so I suspected the MF-2300 is not a good match for them and at the time I don't have the budget to upgrade better and more powerful amp therefore I changed speakers with easier current 6-8 ohm
from then on my system sings the soundstage open up wider, deeper, more details, better bass, better everything hope my tip helps, good luck.
