Confirmed. They are 805 Matrix horizontals. My SCM-1 Nautilus speakers are not D4’s or even Nautilus 805’s but should I save up for the real Nautilus HTM-1 or may I be satisfied with using the two 805 Matrix set together as a second channel. If anyone has had hands on experience please let me know. Sure the HTM-1 is going to sound better but $750 vs $1500, is there really, really a dramatic difference?
