Digital coaxial advice needed

I just found 2 digital aes/ebu sets i used back in 2002.
One brand i don't remember, the other one is signal cable.
I also found 2 custom made Krell cast cables.

Perhaps i should try and see how these two digital cables work first.
If i don't hear much difference, i probably should skip my urge for better (more expensive) ditos. However, i am curious of Inakustiks 2404

I contacted the reseller of the Nuprime combo, he actually suggested to move up from CDT-8 Pro to CDT 10 instead of more "exotic cables".

Btw, how does Nordost Heimdall 2 sound?
Are they thin in lower mid and bass?

I remember the older Nordost were good match for bass heavy systems

Cullen digital cables are outstanding

This is weird that i say now. I had Audioquest Raven aes/ebu. I feel that my Supra IS2 cable sound better, so i sold the Raven. But i ain't to keen on skipping aes/ebu anyway since i don't use DSD needed upsample bandwidth. I like the lower settings if i can generalize!?
That means that even 354kHz often sound unnatural.So the DSD upsampling rate is not for me. As i have understood, right or wrong, this is when the high bandwidth of IS2 is better?
Anyway, i have just ordered a Cardas Clear aes/ebu. I really hope it is way better than what i have now. I still don't know if i can come further with this system. Maybe i would need more resolving speakers than Micromain27!?
Worst issues that i experience is still bass peaks. I dropped about 50% of my absorbers and got two Svanå V-6 bas absorbers set at 40-45Hz. But to be honest, i could use two more + a set of V-4 for 70-75Hz.
