Review: Best value AVR available. - I've been listening to CDs, streaming music, and watching movies for about a month now and have the unit figured out and dialed in. This is a very nice AVR because of its powerful amplifier, pre-outs and overall sound including two independent sub pre-outs. Has the typical features of all the other quality AVRs out there. Onkyo did a firmware update which made it possible to power off the unit's amp in 2 ch mode and then also all channels off. Powering off a unit's amp in pre-out mode and using strictly as a pre-pro prevents signal interference which translates into better/cleaner sound from the pre-outs. Plus, virtually no heat generated from the unit in pre-out mode. This unit runs barely warm with an inaudible fan--not sure if it has one or two. Navigating the on-screen menu is easy and straightforward. One can download the manual onto a PC or flash drive from Onkyo's website which then provides the option to have it printed into a hard copy--which ever pages you want. The manual doesn't explain certain things as well as it could so occasionally I had to google something for additional clarity. However it didn't take long to learn Onkyo's language for set-up and tweaking. Onkyo's customer service has been good for me the few times I called prior to purchasing. Haven't called since owning. This is my first Onkyo AVR. See Gene DellaSala's comprehensive review with all his measurements on Audioholics website to understand what a solid piece of equipment this is and what makes it a great value relative to the competition. Gene measured two channels driven at 170w/ch and was quite impressed with the measurements overall. He also said this unit is a good competent pre-pro. It's quite good for 2ch listening and powerful enough to adequately drive surround speakers during movies because of its great amplifier which is why the unit is nearly 50lbs. Both the RZ-50 and RZ-70 come with upgraded ESS Sabre DACs. The Sabre ESS ES9026PRO is the new DAC. For those who prefer not to go the route of separates; this is the AVR to have in the budget range of 2k. The biggest complaint with AVRs is having to make the trade-off between convenience/features but inadequate power. With the RZ-70, Onkyo created a feature rich and also powerful AVR for two grand. I've had two Denon AVRs and like them but have always been disappointed with their internal amps. Presently, the Denon X6800H is the exact equivalent to the RZ-70 and it retails for $3800. It weighs 34.4lbs while the Onkyo weighs 48.5lbs which has me thinking the Denon amp is inferior for considerably more money. I've run the RZ-70 strictly as a preamp processor in pre-out mode with an Outlaw 5000 power amp and everything works as it should and the sound is very good both ways. I'm driving a 5.1 array of old Polk 70 Series ll speakers which are 90dB sensitive but still require A LOT of power to drive them properly without distortion at medium high volume which is all I can tolerate. The Onkyo's beefy amp also provides for good articulate low volume listening which is important to me. The RZ-70 occasionally goes on sale for under 2k here on desertcart. Manufactured in 2023. Happy listening.
Review: Feature‑packed flagship receiver with real power, elite room correction, and unmatched value - UPDATE: If you’re even thinking about upgrading your home theater, stop waiting and buy the RZ70 while it’s around $1700. At this price, it’s the best value in home audio — in my opinion. Nothing else in this class offers this combination of power, features, and room correction. --- Power & Performance This receiver is a monster in the best way. Onkyo didn’t exaggerate the specs — independent bench testing measured 170 watts per channel (2‑channel), which is rare honesty in this industry. Real‑world performance backs it up: • Effortless dynamics even with demanding speakers • Clean, controlled bass without bloat • High headroom for action movies and orchestral peaks • Excellent stereo performance for music listening Whether you’re running a full Atmos setup or a simple 2‑channel system, the RZ70 has more than enough muscle. --- Dirac Live Included (Huge Value) Dirac Live is the star of the show. It’s included at no extra cost, and it transforms the sound: • Tightens bass dramatically • Improves imaging and clarity • Smooths out room‑induced peaks • Makes even modest speakers sound more expensive Room correction is where many receivers cut corners — the RZ70 does the opposite. Dirac alone makes this unit worth the price. --- HDMI 2.1 & Gaming All HDMI inputs are full‑bandwidth 40Gbps HDMI 2.1, which is exactly what you want for: • PS5 • Xbox Series X • PC gaming • 4K/120Hz • VRR, ALLM, HDR10+, Dolby Vision No handshake issues, no dropouts, no nonsense. It just works. --- Features & Connectivity This is one of the most complete feature sets in the entire category: • 11.2 channels with processing for 7.2.4 • Pre‑outs for external amps • Dual subwoofer outputs • Roon Ready • Chromecast, AirPlay 2, Bluetooth, Spotify Connect • IMAX Enhanced • THX Certified • Excellent app control You’re not going to “outgrow” this receiver anytime soon. --- Sound Quality The RZ70 has a clean, neutral sound signature with excellent detail retrieval. Movies have weight and impact, while music playback is surprisingly refined for a receiver in this price range. With Dirac engaged, the soundstage becomes wide, precise, and immersive. --- Build Quality & Size This thing is big — physically larger than most receivers in its class. It’s deep, tall, and heavy. Make sure your cabinet or rack can handle it. The upside is that the chassis feels solid, well‑ventilated, and built to last. --- User Interface & Setup Setup is straightforward: • Clear on‑screen menus • Logical layout • Easy speaker configuration • Dirac calibration is simple if you follow the prompts Even beginners can get great results. --- Value At the current price of $1,700, nothing touches the RZ70. You’re getting: • Flagship‑level power • Full HDMI 2.1 • Dirac Live included • 11 channels • THX certification • A feature set normally found in $2500–$3500 receivers It’s the rare product that feels like you’re getting more than you paid for. --- Bottom Line If you have the space for it, the TX‑RZ70 is one of the best home‑theater purchases you can make. It’s powerful, clean, future‑proof, and loaded with features that genuinely improve your system. At this price, it’s the best deal in home theater.

- THX CERTIFIED: In 1993, Onkyo became the first consumer home theater electronics brand to be THX-certified, after thousands of tests. No matter what input is used, what combination of built-in features are used, what preamplifier or amplifier, there can be absolutely nothing added, nothing taken away from the source material. And the TX-RZ70 offers four distinct THX listening modes: cinema, gaming, music, and surround EX.

### ⭐⭐⭐⭐⭐ Great Power, Specs, sounds and price... a unicorn!!!!
*by I***Z on January 27, 2026*

I honestly couldn't be happier with this thing. I bought the Onkyo RZ70 to be the main "processor" for my setup, and it’s been rock solid. If you’re debating between this and those super expensive separates/processors, just save the cash and grab this. Audioholics measured it recently and said it had the best test results they've ever seen in this price class, which makes me feel pretty good about the purchase. Zero HDMI Headaches (Finally): This is usually where receivers annoy me, but the RZ70 nails it. My previous Denon was a total nightmare with HDMI handshakes and black screens, but I haven't had a single issue with this Onkyo. I run my PC through it to the TV, and it passes 4K at 120Hz without any flickering or handshake issues. My PS5 VRR works instantly too. Zero problems with my Apple TV and with any Atmos content. It has Chromecast, Spotify, Sonos...literally anything you can throw at a receiver it will accept...and everything just feels buttery smooth. The Audio Setup (It’s a beast): I’m actually using the RCA pre-outs to feed a pair of Hypex Nilai monoblocks for my front Revel F36 towers, while the Onkyo handles the rest (KEF Q250c center, Q150 rears, and Pioneer Atmos modules). The integration is seamless. It has two independent 12V triggers, so my external amps wake up automatically when I turn the receiver on—no weird workarounds needed. Note that I have tried the internal amps for the Revels and they drive with authority! One massive surprise was the internal DAC. I A/B tested it against my Eversolo DMP-A8 (which is a dedicated high-end streamer), and I could barely hear a difference. It’s super clean and detailed. Living with it: I use Roon for music, and the RZ70 pops up immediately as a Roon Ready endpoint. It switches from "Movie mode" to "Hi-Res Music" instantly without glitches. Also, the Web Setup is a lifesaver. Instead of dealing with clunky on-screen menus with the remote, I just opened my laptop browser to rename inputs and tweak settings. Way faster. Dirac Live was also great—it tightened up my dual SVS 3000 Micro subs so the bass is punchy instead of just booming all over the room. The "Meh" Stuff: It’s not perfect. The remote feels kinda cheap and plasticky for a flagship unit, though it works fine. And heads up—this thing is HUGE and heavy. Make sure your shelf is deep enough because it barely fits on mine. But I guess that’s the price you pay for the power. Verdict: Whether you use the internal amps (which are massive) or use it as a pre-amp like I do, it handles everything, it is built like a tank and it is an absolute bargain for the price (you will be looking at $4k at competition, did a TON of research before purchasing) .100% recommended, pull the trigger, you will not regret
