Bob - That's funny, most people I have heard from feel the opposite from you...
My vote goes to Denon & Yamaha. Either, they are an even 50/50 in my book and I won't choose one over the other until I find how much I can get it for. Work for a Denon dealer now.... But it was Yamaha when I had money.
Anyway, why I rule companies out: Piss poor total engineering system combined with lousy customer service. Since I work with Crestron & integration of systems serial control is very, VERY important to me. The following companies have shown beyond a shadow of a doubt that they don't know how to make the serial port work correctly, and have no interest in fixing engineering problems within components that exist to make their receiver better, but insist upon advertising it as a feature despite KNOWN problems with it....
1. Marantz - Marantz has long been my number one complaint. Zero customer support, half their products aren't designed/built in house, and when put in serious tests their power is severely over-rated to what reality shows. Their base logic for building high-end receivers is just stupid on the engineering front.
2. Integra - My phone call went something like "Hello, you have a problem with your receiver, I can't turn it on via serial control." "Okay, if you are aware of this problem, where can I get firmware to fix it." "You aren't going to fix that problem... great, nice doing business with you." So simple, yet they screw it up OH SO BAD!!!
3. Rotel... Can someone please tell me how you are supposed to use the serial port of their receiver AND listen to anything? Because as soon as we plugged in their serial cable (included with the receiver) the speakers started hissing and making noise? Cripes! It's like the speakers hissing as soon as you touch the remote control, except constantly. Talk about something that wasn't tested before release.
Other companies I hold optimism for, but haven't tested. I am strongly of the belief that a company that is serious about its engineering will provide a good all around product and support that product or make it so that product does not even need support. Yamaha and Denon are a step ahead... Let me add McIntosh to that list who I called when the MX-134 came out and did not work via serial control.... Within 1 week they sent me an email with new firmware to fix the problem and it actually worked perfectly. They dove through hoops to make their product better very quickly.
Just a few opinions with reasons behind them.
