I agree they are the same company but each uses their own internal components and design which makes them different. A Marantz receiver cannot be the same as a Denon receiver or even a McIntosh processor since Mac is also owned by the same company. Im not trying to start a war over who is better, I have owned all 3 brands and have my own preference but I have always wondered if the cases were opened and examined closer what percentage are the same parts used in each make? 30%, 60%, 90% because the prices for all 3 range from hundreds to $15,000 for the latest MX-152. But I wonder how many denon/Marantz parts are really inside that expensive Mac. Just thinking aloud.
