Denon - Axioms - Rockets. Sounds like an equation more profound than E-MC2. No downside at all.

As a Denonite (is that a word?), I had an 1803, and have a 1905 and 3803. While I agree with John's assessment (I always do ) about the Debnon manuals, they stop short of being life-threatening.

Once you sit down and take it in sips, you'll be OK. Otherwise, it's like drinking from a firehose. In general, they are robust, dependable and hve all the toys/tweaking you'll need. If you have a MX-850 remote, there is also a stunning array of commands that can be used.

Enjoy the hunt.
