Comparing the Onkyo NR & SR Series AV Receivers

Featured image for Onkyo AV Receivers: the NR & SR Series Compared. Volume control on an AV receiver.
Updated: October 15, 2019

If you want to buy an Onkyo AV receiver, then the first thing you will need to do is narrow down which one is right for you.

Onkyo release a number of new receivers each year. So, it can be hard to find the right model that suits all your needs.

There are three main series to check out when researching an Onkyo AV receiver:

  • RZ Series: high-end models
  • NR Series: mid-range AV receivers
  • SR Series: entry-level receivers

On this page, I will be comparing the models from the NR and SR series.

If you want to take a look at the higher-end Onkyo AV receivers, go to Onkyo AV Receivers: Comparing the RZ Series.

I have grouped these receivers by their year of release - and then by Manufacturer Suggested Retail Price (MSRP).

You will often be able to find a receiver selling below the MSRP. However it is a good guide to an AV receivers place in the market.

The specifications are from the US models and you may find these vary around the world. But, they are often very similar.

If you don't understand all the features, and why they are important, you might want to check out my buying guide to the best AV receivers.

Onkyo SR Series

The Onkyo SR series are for those of you with limited space. They are a slim design which will be easier to install if you don't have much room to play with. Also, they have less features than the bigger models, which can keep down the cost. The SR stands for surround receiver. A great choice if you want to keep the cost down, but still have the advantages of an AV receiver.
