From the Atlas Hyper 2.0 web page ...
"The Hyper speaker cables are available in 1.5 sq mm, 2.0 sq mm, 3.5 sq mm and Bi-Wire options."
So which version did you buy? (I don't recall you saying.)
This (the cross sectional area of the conductor) is, possibly, the most important factor in making any real difference between cables regardless of brand.
Good quality copper and lots of it.
EDIT: Sorry - total numpty here - it's Hyper 2.0 so, of course, it's the 2.0 sq mm version! Duh.
Hmm. Maybe that's why it was so difficult to hear any improvement. Little or no difference - in the thickness of conductor - to your old cables. Did you try the 3.5 sq mm option?
Mmmhh, there are other factors, as important and perhaps more so.
It has been argued that for the average home speaker/amplifier interface anything above 1.5mm sq.mm is overkill and of little practical use. Dielectric (insulation) is also important and the differences in materials are measurable. PVC being one of the least suited materials with air (no insulation) being the ideal but hardly practical. Insulation being sometimes blamed for the 'smearing' effect.
Then there is the arrangement of conductors, also measurable. Spaced, parallel, litz etc etc.
Then there is the make up of the conductor ... stranded, solid core, stranded and solid combined, copper, silver plated copper, spacing of the conductors themselves ie. bundles, flat and solid, wound around an air tube or air tubes etc.
The naysayers will as always argue that none of the above is within the realms of the audible in normal home hifi length. The ones that actually have used different cables as opposed to use google searches as scientific evidence will probably be able to tell the accumulated effects such differences of construction can have.
Best to find out for yourself rather than take my or anybody elses word for it.
Why not make your own cable and combine some of the (reported) best practices?
Should be fun and much cheaper.
To put it all in context though, any changes will be very subtle unless you use the thinnest bellwire you can find which will have the archetypal valve amplifier affect at the frequency extremes will most speakers as TrevC recently pointed out (one of the few things TrevC often points out that I do agree with).
Still, if you have a well sorted system and possess acute hearing it is my humble opinion that playing with cables (both speaker and interconnect) can indeed provide very subtle tone controls except that any control will sway the minus (-) way with the exception of the lack of electrical control allowed by the amplifier on the driver due TrevC's example.
