FYI, every XT 32 box also has Sub EQ HT.
So far, I believe you're correct, although the
Products with Audyssey Technologies site does show the Integra DHC-80.2 to have XT32 but not Sub EQ HT (probably in error). They're not necessarily mutually inclusive technologies, however... there are indeed several AVRs with Sub EQ HT but "only" MultEq XT.
I want both.
