User reviews

Review highlights

  • The vast majority of buyers are enthusiastic: the TX-RZ50 delivers powerful, precise, and dynamic sound, both for home theater and stereo, and represents a clear upgrade for many compared with their previous Yamaha, Denon, or Onkyo amplifiers.
  • Dirac Live calibration is unanimously praised as a major differentiating asset, especially as it is included free of charge whereas some competitors charge for it as an option.
  • Several buyers consider the remote control too lightweight and lacking backlighting, including some who gave the product a 5/5 rating.

A very good amp in terms of specifications and supported audio standards; Dirac really adds value for home theater in an attic room, which is therefore complicated in terms of sound reflections. The sound is lively, detailed, and dynamic in both home theater and stereo (without Dirac).
BUT the software side is simply outdated, and don't expect to connect it to 5 GHz WiFi without tearing your hair out, because the thing disconnects pretty much whenever it wants and it's impossible to reconnect it without unplugging / plugging the power back in.
You've been listening to music on Spotify and decide to watch a movie on the TV? eARC doesn't automatically switch to the TV input, but it works on the Blu-ray input (non-eARC), as well as between the TV and BR inputs. But from the NET input (Spotify, Tidal, etc.) to TV, no way. So you have to switch manually with the remote control; that's the final straw: this thing is simply unworthy of a product in this range. Small, plasticky, unlit, with tiny buttons—it looks like they finished with this and there was no budget left.
As for ergonomics, well, it's Onkyo. You need bionic eyes to use the buttons on the front panel; leave the interface in English, there will be fewer approximate translations from Japanese, and this front display is the same as that of Onkyo units from twenty years ago. Unworthy, I tell you.
In conclusion, if you want to make this amp work the way you like, you have to earn it (Japanese concept), set it up - ah, it disconnected, hard reset: Dirac settings to redo - set it up again, assign it its own 2.4 GHz WiFi network just so it stays connected (more than enough for lossless audio), and then you'll love it like I do and won't want to put it back in its box.

Un très bon ampli du point de vue des spécifications et des normes audio supportées, le Dirac apporte vraiment un plus pour le home cinéma dans une salle mansardée donc compliquée au niveau réflexions sonores. Le son est vif, détaillé et dynamique en HC comme en stéréo (sans Dirac).
MAIS, la partie logicielle est tout simplement hors d'âge et ne comptez pas le connecter à un WiFi 5Ghz sans vous arracher les cheveux car le bougre se déconnecte à peu près quand il veut et impossible de le reconnecter sans débrancher / rebrancher l'alimentation.
Vous avez écouté de la musique sur Spotify et vous décidez de regarder un film sur la TV ? L'eARC ne bascule pas automatiquement sur l'entrée TV, mais sur l'entrée Blu Ray (non eARC) ça marche, de même qu'entre les entrées TV et BR. Mais depuis l'entrée NET (Spotify, Tidal, etc) vers TV pas moyen. Donc il faut basculer manuellement avec la télécommande, ça c'est le bouquet final : cette chose est tout simplement indigne d'un produit de cette gamme. Petite, plastoc, non éclairée avec des boutons minuscules, on dirait qu'ils ont terminé par ça et qu'il n'y avait plus de budget.
Côté ergonomie ben, c'est Onkyo. Il faut des yeux bioniques pour utiliser les boutons en façade, laissez l'interface en anglais il y aura moins de traduction approximative depuis le japonais et cet écran en façade est le même que celui des Onkyo d'il y a vingt ans. Indigne je vous dis.
En conclusion, si vous voulez faire fonctionner cet ampli selon vos goûts, vous devez le mériter (concept japonais), le régler - ah il s'est déconnecté, hard reset : réglages Dirac à refaire - le re-régler encore, lui attribuer son propre réseau WiFi en 2,4 Ghz uniquement pour qu'il reste connecté (suffit largement pour l'audio lossless) et là vous l'aimerez comme moi et vous n'aurez plus envie de le remettre dans son carton.

Great amplifier with (too) many possibilities. Installation is easy, with the choice between a quick menu and an extensive menu. The latter takes some time but is recommended.
Setting up the speakers (Focal Theva 3D set) can be done manually or with the microphone (Dirac Live). I am still experimenting with the latter. I connected the rear speakers to the back-surround, but DIRAC recognizes them as surround speakers. The preset option to set them as back-surround is missing, and I have not yet figured out whether the surround (Atmos) comes across properly this way.
In any case, DIRAC takes some time, and I am still working on it.
Furthermore, an excellent and user-friendly amplifier with many useful shortcut buttons on the remote control and separate settings for vocals and high and low tones, on top of the wide choice of presets. The latter is standard with many brands, but I prefer to adjust things myself.
Homecine Solutions recommended this amplifier in combination with the aforementioned Focal set, and I do not regret it.
Very happy with it.

Mooie versterker met (te) veel mogelijkheden. Het installeren gaat makkelijk waarbij je de keuze hebt tussen een quick menu en een uitgebreid menu. Die laatste kost wat tijd maar wel aan te raden.
Het instellen van de speakers (Focal Theva 3D set) kan handmatig of met de microfoon (Dirac live). Met die laatste ben ik nog aan het stoeien. Ik heb de achterspeakers op de back-surround aangesloten maar DIRAC herkent deze als surround speakers. De voorkeuze om ze als back-surround in te stellen ontbreekt en ik ben er nog niet uit of het op deze wijze het surround (Armos) goed uit de verf komt.
Hoe dan ook,DIRAC vergt wat tijd en daar ben ik nog mee bezig.
Verder een prima en gebruiksvriendelijke versterker met veel handige sneltoetsen op de afstandsbediening en aparte instellingen voor vocal en hoge en lage tonen bovenop de ruime keuze aan presets. Dat laatste is bij veel merken standaard maar ik regel liever zelf bij.
Homecine Solutions heeft deze versterker geadviseerd in combinatie met de eerder genoemde Focal set en ik heb er geen spijt van.
Erg blij mee.

This Onkyo TX-RZ50 is fantastic: it has incredible power and crystal-clear sound. When I watch movies, it really feels like being at the cinema, with amazing effects and voices that are always clear. The automatic calibration works wonders and adjusts the speakers on its own according to the room. The only thing I’m not crazy about is that you can’t keep the type of audio signal currently being transmitted permanently displayed on the screen. Apart from this small detail, it’s very easy to use and rock-solid. Extremely happy with the purchase, highly recommended product!

Questo Onkyo TX-RZ50 è fantastico: ha una potenza incredibile e un suono pulitissimo. Quando guardo i film sembra davvero di stare al cinema, con effetti pazzeschi e voci sempre chiare. La calibrazione automatica fa miracoli e regola le casse da sola in base alla stanza. L'unica cosa che non mi fa impazzire è che non si può vedere fisso sul display il tipo di segnale audio che sta trasmettendo in quel momento. A parte questo piccolo dettaglio, è facilissimo da usare ed è una roccia. Stracontento dell'acquisto, prodotto consigliatissimo!
