Sigma-delta DAC, FPGA platform

Thanks for reply.

Ok, I've looked at this DSP kit with Cyclone II, but I have another questions...

Why DSP kit with next generation of Cyclone (Cyclone III) costs 1000$ more? And what main differences are between those two kits? Workflow, usability, features? Maybe someone of You have used those two platforms and can say "empirically" about differences in use.

Another issue are those Altera's partnership platforms. I was looking at Altium Nanoboards and Terasic DE2/DE3 with HSMC converters. What do You think about it in comparison with Altera's Cyclone II/III DSP Kits?
