Just seen on Facebook that EBS have a new head put for NAMM - it's (presumably) class A/B, will be completely solid state and, for now at least, the only rack mount head in the range. I wouldn't be surprised to see a Fafner replacement on the horizon at some point though. It looks right up my street, particularly as I will need to replace my HD350 at some point, I just hope that as this us described as going back to their roots, they've voiced the filters like they used to. https://ebs
