I had the opportunity to upgrade my Onkyo 797 to the 898 due to an extended warranty issue that couldn't get resolved. I had to pay about $200 more for the 898 than what I paid for the 797 back in November. I won't be picking up the new unit until Saturday and it will be used for 5.1 only for the time (the 797 was being used for 5.1 only, no room for the rear surrounds yet ). My current speaker set up consists of five NHT SB-1's and a Paradigm PS1000 subwoofer. I am curious if anyone thinks I may have wasted the $200 on the upgrade to the 898 or should I have just taken a new replacement 797?
