I owned the Watt7's/WATCH Dog and moved to the Maxx 2 with amazing improvements in scale, life-like imaging and big as life dynamic contrasts. The scale of sound took on dimension. Orchestral music thundered and had presence I never heard before etc...
The Watt7's painted images with great detail and monitor like specificity. The Maxx 2's filled in those images with tremendous weight, dimensionality and pitch articulation that was beyond the 7/WATCH combo. The 8's seem a warmer, more liquid and linear version of the 7, but still..... Maxx 2= True to life Watt 7/8 life-like..
As always IME
