I have one unit available. Very low mileage, essentially lived in the shop as the back up DSP when everything else was in use. The unit has the T version firmware installed and can be computer controlled with the London Architect software. It's in good operating condition with no fading of the display. $800 or trade for an Ashly Protea 4.24C DSP. Yes, the BSS sounds better but I have twelve Ashlys and the one BSS and having all the same would make life easier.
