If you have just got the red fuses, do they have a 30day trial.
It might be more worthwhile to get the black fuse to try as it seems to suggest that they are much improved over the Reds.
As for HFT's, placement and knowing your room , effects of sound and room treatments will key to obtain the greatest benefits or notice not much. The HFT's are effective but a knowledge is required.
Not knowing how your room is, otherwise, changing the fuses might be a more greater improvement - more like changing up a to higher level cable of the same manufacturer.
