What was the best addition to your HT in 2009?

[Fors*]

I think the title says it all. With the year winding down, I'd like to know from everyone what addition to your HT had the largest, most positive impact on either your PQ or AQ in 2009. This is not to be defined by money spent, but in terms of how significant of an improvement the new addition contributed for either your PQ or AQ.

IMO, my Pioneer Elite SC-05 had the biggest impact on my HT this year. I used to have the Onkyo 605, but the Elite gave me additional power, a more dynamic sound, pre-outs and the ability to do a ton of tweaking to satisfy my needs. I did have a lot of new additions this past year, but I think everything else in my audio feeds off of my SC-05. I did add a projector too, but I simply don't use that enough to justify that as having the largest impact for my HT.

How about you guys?
