DCS Scarlatti v the Spectral SDR 4000 pro

I use a Spectral system with the DCS three box Scarlatti system. I wonder if anyone has experience of the the Scarlatti system in comparison to the Spectral SDR 4000 pro.

A friend had the Spectral and sold it for the Meridian 808.2. He had than 861 before the Spectral and the dCS stack before that.
Suggest you give Goodwins High End (no affiliation) a call as they carry both.
