8351C
More powerful amps
Redesigned drivers
More power is always better but does not obsolete anything.
The drivers - I don’t know much about that. What parameters could be improved and for what purpose?
Off the bat the first thing I realized when reading the 8361a review is that the first thing to require protection was the tweeter. Given my recent experiences with the 8341 this sounds about right. I can get them to self protect on music without any bass.
I hate to say it but the mid/tweeter on these causes an SPL limit which a person using these for listening in a mid field setting might run into. However since I value quality over quantity I can accept that and just turn down the volume.
Also Amir published the graph and said it’s not audible. This mirrors my experience as well. That light seems to be coming on a lot well before any audible issues. I just covered that damn light.
Any day of the week I’ll take the limits of the mid/tweeter in exchange for that sweet large and forgiving sweet spot. Nothing is more important for me in a practical sense of listening to stereo music. Having a constrained sweet spot is annoying.
So yes perhaps like they did between 8351a and 8351b they will improve power handling.
