You might want to compare the 4806 with the lower end of the '06 line, that being the 3806 and 4306. While the 4806 is very spiffy (little brother of the 5805), it's a lot of cash. If you can get the features you want in a less expensive Denon, then you can have the extra money left over for an external amp(s) to fulfill your need for more power.
