I disagree, I find the TX-6 and OB-4 at least highly functional tools without peers. There are no mixers with the function of the TX-6 and the next closest comparables are still near the same price with several major gaps.
OB-4: The only other one I found which isn't just a bt hifi and tries to be an actual studio monitor is the iLoud, there is a new product from Fender as well. I also have the iLoud and stopped using it (worse sound, fewer useful tools). I don't think these 1-2 alternatives are clearly superior value.
