Honored Contributorthe Cyclone III DSP board is much more powerful FPGA wise is probably the biggest difference. it also has ethernet, a display, 8x more SRAM, and supports HSMC daughter cards
EP2C70 vs EP3C120 LE: ~70k vs ~120k mult: 150 vs 288 RAM: 1.1Mbit vs 3.9Mbit i don't know much about Altium's offerings. the DE2 doesn't have HSMC, but they do offer the ADA-GPIO for adding ADC/DAC to the DE2 and DE1. i don't know what the frequency response of their converter setups are. with the DE2 you're down to a EP2C35 device, ~35k LE, 35 multipliers, etc. the DE3 moves up to a Stratix III device with an HSMC connector so you could use the ADA-HSMC. the board doesn't feature an audio CODEC and i don't know if there's a solution available to add it (via GPIO headers or HSMC). this might be something you have to make.
