I just heard that driving some Avalon's - it's a different sound to the old Krells at least the FPB cast series. It is smoother on the top and more open sounding and resolving with slightly more body but it doesn't have the bass slam. There is more bass texture in its place. I think nothing I've heard has the bass slam and grunt of those old Krells.
Lucky you! I haven't heard it yet, how does it look? I see, well thanks for your short review.
There's also the BSC amps from Dan's son Bret if you like the old Krell sound. I'd like to hear those too.
