It used to be that picking up an entry-level receiver meant settling for the absolute bare bones and getting little in return for your investment. The latest from Onkyo buck that trend by offering much more than one might expect from low priced receivers. The TX-SR313 is the cheapest in the series ($299) and still packs a discrete-component output stage instead of an integrated amp.
$699 will get you the 7.2 channel NR616 network receiver, complete with THX Select2 Plus certification, streaming from MP3tunes and Spotify and Qdeo video processing that scales video up to 4K if you have a compatible display. The NR515 ($599) offers many of the same features but drops things like a third zone out. The NR414 ($499) is another networked receiver in the line that runs a bit cheaper thanks to the reduction to 5.1 channels.
