Also Masimo kept far too many product brands. There absolutely needs to be some rationalization especially in the speaker lines. There also needs to be some rationalization between Denon and Marantz or may be one of them disappear.
I don't know about between Denon and Marantz... you really should be calling it between JBL, Arcam, Denon and Marantz...
JBL have just launched a completely new AVR series (the MA range), the Arcam shared JBL's seem to be in a phase out stage, with the Trinnov based model as the flagship but the rest.... and there really has not been any new developments in the AVR space at Arcam for a long time either.
So JBL flagship... Arcam perhaps will drop its AV range, and revert to a stereo/audiophile brand, Denon and Marantz already share a lot of components, boards, transformers, etc... within their ranges, which makes it relatively efficient - Lexicon is already pretty much dead as an AV brand.
Both Denon and Marantz seem very much alive in the marketplace, with buyers having a higher awareness of those brands, than they have of JBL, Arcam, or the others in the "library".
If they have to cut somewhere... D&M wouldn't be where I would be logically focussing.
On the other hand, those sort of cuts often have an internal office politics component... and economic logic is not always the primary driver.
