Since you have 12ga and want an improvement then by all means go to 10ga wires. This will have lower overall resistance than your monster cables by about 30%....although 30% improvement on a very small number is still a small number and of only incremental benefit - hardly worth it. (Compare this to the fact that 12ga is more than twice as conductive as 16 ga, arguably a worthwhile improvement for longer wire runs)
The comments above are according to electrical engineering and ABX blind testing, which say that the differences are likely to be imperceptable in almost all cases - call this the rational view.
Testimonials from many audiophiles, cable manufacturers and Hi-Fi shop floor salesman often tend to contradict science and blind tests; call this the irrational or anecdotal view ( a view which makes people worry that what they have is not good enough). Going for big or better speaker wires would remove the irrational fear of degradation in sound from lesser quality "cheap" cables.
I don't think it matters which view, rational or irrational, is correct (who knows, there will always be debate), but it certainly matters if the irrational fear affects your listening enjoyment even when you know you have what should be rationally good enough cables, in which case it is probably worthwhile addressing. (This is akin to the sports athlete who carries Mom's letter in his sock and wins....it doesn't matter that the letter has no scientific basis for improvement if it works)
However, if you bring yourself to accept the rational view then you can save some money and put it towards an improvement elsewhere.
