Hi Sushi
I have one HT/music system driven by a Toshiba SD9200 DVD Audio player and another by a Philips SACD 1000. These multi channel (direct) formats are pretty dramatic and work especially well for rock, blues, celtic faery folk. I haven't found any classical orchestral multichannel recordings which work for me.
For kicking back and enjoying music, my favorite is a 5 watt per channel tube amp driving a pair of M50 like speakers and an 8" Velodyne sub (just received my partsexpress.com Vance Dickason 10" Titanic Subwoofer kit which I will swap for the Velodyne this week end). This system is sourced by an Ah! Njoe Tjoeb tube output CD player. Enormous soundstage, high and wide, beautiful, beautiful music. Getz/Jobim's CD sounds like someone is singing in my living room. Jazz? Sounds pretty darn realistic. But orchestral/symphonic music? Nice to listen to but no mistaking it for the real thing.
Maybe someday!
