Hi...Raspberry Pi has two i2s inputs (header, HDMI). You could potentially delay the data with a simple FIFO written in a tight real-time loop in software after reading in the data from an i2s input board.
The TAS3251 is an interesting chip but the bring-up on it is heavy. It's a very complicated device and requires a lot of heavy lifting to get something basic working. Unless you're planning on making a ton of these devices, you're better off with the pricey evaluation board just for basic DSP/DAC hacking.
