How do Mark Grant interconnects compare to the following?

I am thinking that Impotentially have a "weak" interconnect in my system that by replacing it may give slightly more sound quality.

My basic system is as follows for headphone use.
Sl1200 Mk2 connected to Graham Slee Reflex M with the Audio Origami Van Damme cable.
Reflex M connected to Arcam Alpha 8 with a Mark Grant Canare LV61S.
Alpha 8 connected to Graham Slee Ultra Linear Solo with a Van Den Hul "The Source".

For speaker use, it's obviously the same to the Amp, but I have an Alpha 8P connected with a Van den Hul D102 MkIII, and from there I have a pair of Cyrus CLS70's connected with Van Damme Tour grade 4 x 2.5mm speaker cable.

If I was going to replace any one cable I think it would be the cheap Mark Grant cable, with a G1500HD.
I don't think the rest of my system merits spending much more than this.

However, what I am wondering is if I should replace all of my cables with G1500HD, and if that would give me a better sounding system than the Van Den Hul cables currently give.

Even the basic MG cable does a fine job and may or may not improve on the Van den Hull. I think at best you might get a small difference but it all may come down to synergy. What area of sound reproduction do you suspect is lacking that you can attribute to certain cables? The only difference in the various Mark Grant Cables is the plugs.

I have went up through Marks hierarchy of cables as funds have allowed. Improvements come with every step and fortunately Mark lets you trade in as you move along.
