As we all know, we base our purchasing decisions on our own experiences as well as our friends'.
And how we feel today may not be the same as a few years ago or a few years from now.
1. Currently, it seems Yamaha might be the most reliable major big brands (Yamaha, Denon, Marantz, Pioneer, Integra, Anthem, Sony, etc.).
2. Yamaha also appears to be the only major big brand to extensively tests for HDMI compatibility.
@M Code might elaborate on Reliability and Compatibililty.
3. The Yamaha WiFi remote app and WiFi music streaming app (MusicCast) is the best I've ever seen compared to all the other brands.
4. Service and Warranty. I think Yamaha's customer service is better than the other brands. For warranty, usually if you have a problem with your electronics, you look for Authorized Repair shops near you. For example, for Denon/Marantz, there are 20 authorized centers listed in the USA (some are closed now because of COVID19). But if there is not local center, then you have to ship to Panurgy in NJ. Or if the local shops cannot repair your Denon/Marantz, then they also have to ship to Panurgy. But Denon/Marantz will not pay for shipping to Panurgy. The customers have to pay for shipping to Panurgy even under warranty. I'm not sure if the local shops will ship to Panurgy for free or will make you pay. But the DM websites say the customers are responsible for shipping to Panurgy.
In contrast, Yamaha will pay shipping BOTH WAYS for both brand new and refurbished components.
5. I believe M Code also mentioned that Yamaha keeps everything or most things In-House, instead of Out-Sourcing to other companies. Other brands will out-source most things.
Of course, like all brands, there are pros and cons depending on what's important to you.
1. If you MUST have a certain Auto Room EQ (Anthem ARC, DM Audyssey, Dirac, Trinnov, etc.), then you should go with the brands that have these features. Yamaha has YPAO 64-bit, but I think some people consider this inferior to Audyssey and other auto room EQ. I don't care about ANY auto room EQ. I only care about MANUAL Parametric EQ (PEQ), and Yamaha has a 7-band manual PEQ for each speaker, which is great for me. So if you don't care about Auto Room EQ, then it is not a factor.
2. Downsampling of music files when using Auto EQ. Most brands (Anthem, Denon, Marantz, etc.) will Downsample music files to 48kHz. But Yamaha will not downsample and keep at full 192kHz. I don't care about this, but some people do care about it.
3. Pure Direct/Direct Mode. Some people want Direct Mode, but also want to use their Subwoofers in Direct Mode. You can do with Denon/Marantz, but you cannot do this with Yamaha. With Yamaha, using Direct Mode will not allow the use of Subwoofers at all. So Yamaha' Direct Mode forces you to use FULL RANGE Large towers. I don't think there is a difference in SQ between Pure Direct vs Stereo or Straight Mode.
Since none of these "cons" affect me and the SQ is second to none, my main focus is on Reliability, Compatibility, WiFi Remote Apps (very important to me since my components are in a closet) and WiFi Music Streaming (MusicCast). I love Yamaha MusicCast. It is so easy for me and works 100% for me.
But again, this is the CURRENT state. Things may change in the future.
