From what I have been reading, Denon does not have as good of sound as Marantz, is this true?
The AVR-1913 Can be had at macmall for less than $300 refurbed..it's 7.1ch.
However..on amazon, it has 11 1-star ratings.
The AVR-1613 has 5 1-stars, and the AVR-1513 has 0 stars,
Reading the reviews on the 1713, it has many issues with the HDMI boards going out, others say it went bad in less than 6 months.
The next cheapest 7.1 is the AVR-E400....but it's $500 everywhere.
So it sounds like to me that the 15/16/17 13 line was pretty crappy with the HDMI.
So far, I've settled on marantz.
