The KRELL K-300i, if it has the internal DAC is great for TV and Bluray via HDMI. The DAC itself is just OK for music but I loved the HDMI on those 2 sources. The video is supposed to get some benefit to on the ARC return. I do not know enough to say if that was true.
The streaming on the K-300i gives you the option of saving money on a DAC and streamer. You can improve upon both but that can be done slowly in the future. The K-300i can be a 1 box solution.
I ended up getting a higher end KRELL XD stereo amp because the KRELL K-300i was so good.
