If you click on the products, it tells you what they are. Icarus I is the DAC/Bluetooth amp, II is a high res DAP with dual memory card slots, III is a multi BA iem and IV is a "Quad Drive" design (no idea!).
If these are related to Bob's previously announced project with Sagaris Acoustics, I think the price will be a bit higher than the previous Trinity offerings. Will be very interested to see the pricing and details on these in due course!
