In conclusion, the Onkyo TX-NR5100 is a versatile and feature-packed receiver that delivers excellent sound quality across various types of content. Its focus on enhancing the gaming experience, compatibility with multiple streaming platforms, and seamless integration with smart home ecosystems make it an appealing choice for those looking to upgrade their home theater system. While it has some minor drawbacks, the overall performance and capabilities of the TX-NR5100 make it a solid choice for anyone seeking a future-proof and immersive audio-visual experience.

When looking at the lower levels of the performance ladder expectations should always be at check. Onkyo had so far managed to impress us with a couple of their latest releases and we had high hopes for the TX-NR5100 being a great solution in its more affordable market. And although it did manage to tick most of the required boxes such a model has to, to be considered a worthy purchase, it was not without a few missteps.

The TX-NR5100 does have its positives -- excellent sound quality is one, alongside its comprehensive streaming suite. If you really must have 4K 120Hz, then go, have at it -- the Onkyo TX-NR5100 offers features that few other competitors can match. But be aware it's a model poorly suited to the enthusiasts it's trying to cater for.
