Not an endorsement of this CAD, but I do like this company's iFace; it is economical and works great for cabinet IRs. I know you can load IRs by using other tools including Reverbs like Cakes Perfect Space; still the iFace is handy and well thought out. I would suspect that the CAD will be decent, but right now I am still saving for other toys.
Do let us know what your think of this new CAD.
