I have just checked with Pathos Acoustics directly in reference to the possible release of the new Classic One Mk IV integrated amplifier and they have no idea such a version was even available.
The current version is the Mk III unit, which is only three months old, since its initial introduction to replace the older Mk II unit.
I hope the above information is of assistance.
