I sold the original 804N's for years and have to agree with above .If you going to go HT with these the rare Due might pop up for rears but you'll have a great HT timbre matched set with the $1200 Gallo center.Would suggest you look at the Class D amps sold here by Underwoodwally.Great reviews and much cheaper than other Class D.Always thought the 804's gave up imaging and you'd be better off with 805's and fast sub or go to 803's (used for $3K either N or S are great speaker and work well with different amps.Great Soundstage too).Go for Gallo's.SF's are great for piano and concerto music but given what you music described not forward enough.I am thinking of same issues but thinking Usher,Totem,or Dali since I tilt toward tunes and HT is much less an ambition.But if you look at price Gallo's HT is hard to beat.
