I am probably the least qualified of people here to ascertain sound quality but this weekend gone, I went to a HiFi Show in which Sony were demonstrating 4K HD Video. The sound was via 5.1 Sony Speakers that looked identical to these new ones being discussed. All I can say, is to me, they sounded really, really crap - I was quite shocked & remember thinking to myself, how such nice looking speakers & top end ones could be so uninspiring to even a noob like me. I was kinda hoping they would really making a statement of just how good top end Japanese speakers can sound but it this was simply not the case. Decades ago, I heard the Yamaha NS1000M's & even now, I remember that they were way better in every way than these new Sony Speakers!
