not to sound like a broken record, but i've had my 170 mains for about 3 months now and i remembered reading somewhere someone listened to 2-ch music and the soundstage is excellent that the voice was coming from the middle. so i turned off my 340c and my 200 surrounds, popped in norah jones last night and sure enough, her voice is coming smack down the middle where the 340 is!!! i pulled my wife from the other room and she usually doesn't have ears for these things, and i asked her where the sound was coming from, and she said the same thing...omg. outstanding performance and value, 2 thumbs way up dave f & james!!! the 170s still surprise me
