As far as I'm aware, it's still the Storm and Trinnov processors. Of these the Storm is a bit cheaper but the Altitude 32 is the one to go for IMHO. You may be able to find ex dem units but you would still probably be looking a prices north of $20k.

Main system - Sources (Kodi-HTPC, Vero 4k, FireTV, Sat) into Trinnov Altitude 32 (8-16) (+Roon), Trinnov Amplitude 8 amp & Vivid Audio (Giya G3, V1.5) and REL Stentor III speakers. Others: F80 + Raspberry Pi and other Pi systems.
