I would certainly say that the non BE 718s are a bit. I rarely see anyone except Neil Gader even bother to point out that a component is a bit "darkish sounding." excluding His H(i)Pness, who routinely still does. It can be a bit frustrating to try to determine if something one might want to buy, but may not be able to audition is worth auditioning.
For my money, I want to know if a component hues strongly towards yin or yang, or slightly enough that the back wall does not disappear into the dark.
The older Usher 718s do seem to slightly disappear into the dark, but I don't know about the new ones. Too Bad they never released that kit they said they might for loyal owners of the original Ushers to upgrade their speakers to the newer level, like Dave Wilson does.
