I have (3) different systems....

* 1 for just music in the den
* 1 for movies in the family room
* 1 for music in my home office

My favorite is the music system in the den, Marantz 2600 the most powerful stereo receiver ever built. 400Wx2, quartz-lock tuning, scope. Plus we have an extensive collection of audiophile vinyl and CDs..
Since we do product development/sourcing for certain major clients, plus AV install for home automation we have access to a lot of awesome products...

Just my $0.02...
