flowbert69I always use optical. In addition, you can buy old DVD audio players with really good DAC's built in. I got a Pioneer Elite from ages ago for like $50 and the DAC is amazing. I just use the optical out to CD/DVD audio player, then connect that to my amp. It is amazing. I am debating whether to buy a couple of these and have surround sound for my TV. Do you know of anyone using a bunch of these with a pre-amp/singnal processor? It seems reasonable. These things have more than enough power.
