@M Code has been saying for years that Yamaha is #1 in reliability and HDMI compatibility.
I recently switched from being a very long-time Denon/Marantz user to Yamaha because I wanted to see if Yamaha is #1 in reliability.
Well, alright, I've had some bad experiences with D/M and especially their repair services - Panurgy (they SUCK).
The very last straw for me was when Panurgy could NOT repair my $7500 Denon AVP-A1HDCI - not once, but TWICE. And this was under
100% Best Buy Store Warranty!
I've only been a Yamaha user for 2 years now. But so far, my impression:
1. My Yamaha CX-A5100, MX-A5000, and RX-A3080 operate so much COOLER than ANY Denon/Marantz I've ever used in my life.
2. The Yamaha WiFi remote app works 100% better to me than the DM remote app.
3. HDMI has been more reliable to me with the Yamaha.
4. WiFi Music Streaming has been more reliable to me with the Yamaha.
5. Yamaha will PAY for shipping BOTH ways for any warranty services - Brand New & Refurbished via Authorized Dealers.
6. D/M use Panurgy repair service in New Jersey as their MAIN center. You have to pay for shipping to them even under warranty if your local D/M repair shops cannot repair your component (if you have a local D/C repair shop). I wouldn't touch Panurgy with a 10ft pole based on my multiple experiences with them.
So with only 2 years experience with Yamaha, I can't say much about long-term reliability, although the MUCH COOLER operating temperature might be ONE indicator.
BTW, I used THREE 120mm fans on my $7500 Denon AVP-A1HDCI. Still broke after about 8 years. So there goes the hypothesis about how using FANS (THREE 120mm fans) should extend reliability.
But.....there are people who have NEVER had any issues with Denon or Marantz products. BTW, most of us group Denon and Marantz together. They are under the "D/M" group now owned by Sound United.
As an authorized dealer for both Yamaha and Denon/Marantz, I truly hope that Sound United will FIRE Panurgy and (please for the love of gods) use somebody else much better than sorry Panurgy.
D/M does have the very awesome Audyssey Editor App (which is NOT free and SHOULD be FREE). This app is great for people who love to use EQ for their sound.
So
Sound United - please FIRE Panurgy, make the Editor App FREE FREE FREE with all D/M users, and give all D/M users Free Shipping BOTH WAYs for Warranty service like YAMAHA.
