I have heard the new "lossless" formated true hd formats and they are quite good but I think the only way I will get them is by maybe hooking a Oppo blue ray player to my Yamaha with analog cables, that will be enough for me. I just mostly listen to music and watch Dish network programs that don't have Dolby or DTS encoding. For me I think my money will be better spent on the music reproduction side and keeping my theater for the occasional movie or blue ray and keeping that part of it simple.
