Sorry for the urgency but I am anxious because I think I had an error. I have boughtHarman HK-TS 9 speakers https://www.amazon.it/gp/product/B003S9VW84/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 and Sony STR-DH550 ampl. https://www.amazon.it/gp/product/B00HRW0HR0/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 Can I connect those speakers? Please help me to take away the anxiety. Thanks
