In my personal system i use both the 938 and the Talon Raven C (well this last one has been modified with external crossovers rebuilt with top quality components).
The midrange transparency and imaging of the Hyperion is clearly ahead but the Raven have incredible bass, deep and quick, and the Accuton tweeter has very low distorsion, i couldn't choose between them...
I just received the 968 this morning, it's one of the first time i'm so impressed by a speaker just taken out of the box, not even broken in.
The 968 bass seems to be nearly as deep as the Talon, the treble adjustement is very useful and the overall sound is a bit fuller and more natural, transparency and air seems to be a bit above the 938 too.
The speaker just worked for 5 hours... i wonder what will happen in the coming days / weeks
