I recently shot an email to Anedio about future plans, so I'll post here if I get any info. I do recall they were planning for an eventual D3 version, which they realized would have to support DSD. But I don't know where it stands. They were really focusing most on their speaker amp, to replace the somewhat short lived A1. If it comes to fruition it will be a beast, fully discrete with some unique design aspects.
Thanks. Please do keep us updated.
