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 Amazon. Manufactured in 2023. Happy listening. ### ⭐⭐⭐⭐⭐ Onkyo tx-rz70 é um receiver M-A-R-A-V-I-L-H-O-S-O!!! Melhor, impossível!! *by on Reviewed in Brazil 8 November 2025* Não poderia ter escolhido receiver melhor. Ele vale cada centavo do valor. Por 16 mil tenho o top das galáxias da Onkyo e que tem mais recursos e tecnologias de outras marcas (Yamaha RX-A8A) que custam mais de 25 mil reais. O Onkyo tem o Dirac que é um programa fantástico que ensina onde colocar as caixas acústicas e subwoofer além de equalizar o som como um todo para eliminar distorções, vazios (locais onde o subwoofer não é ouvido/sentido). Antes dele, tenho um receiver Yamaha que faz bem menos e custando bem mais. A Yamaha é uma marca de excelência mas cobra preços absurdos sem razão pois oferece menos tecnologia e recursos que o receiver tx-rz70 da Onkyo. Estou muito feliz com ele. Vale super a pena. ### ⭐⭐⭐⭐⭐ Onkyo txrz70 tope de gama *by on Reviewed in Mexico 25 March 2026* Onkyo txrz70, es el mejor receptor que he tenido, pase por technics, Yamaha, Pioneer y un primer onkyo en el 2010.
