Onkyo's TX-NR838 receiver offers an impressive list of features, not the least of which is support for Dolby Atmos surround sound up to a 5.2.2 system.
Yamaha's A-S2100 is built like a tank, but as nimble as a ballerina. What it lacks in modern day features, it makes up for with impeccable performance.
With high-current amplification, outstanding versatility and the best room-correction package we've ever used, this receiver belongs on every short list.
