auxinput, I finally bought the Theta CB III HD. Got shipped. Opened the box, it's black. Looks good. Its about 10 years old, upgraded from CB III to III HD last year. Trying to determine if I should further upgrade ...
I am also looked at MINIDSP DDRC 88D/BM to have the room correction ability. It is not as powerful as DIRAC of CB IV or IVa, but good enough for the money. BM option give option to control the Subs as well.
