Have you considered using active speakers? I have set up a 5.1 HT system for my mom in 2011 as Christmas gift. It included a Marantz AV7005 processor, five Focal CMS-50 active speakers, and a Focal CMS sub. The connections from the processor to the speakers were all fully balanced cables. The whole package costed about $5600 new at that time. After adjusting the room correction in the Marantz, the result was quite spectacular. If your budget is limited, you can replace the two real speakers with the smaller Focal CMS-40. Or if your budget allows, you can add two more CMS-40 to the side to make it 7.1 and/or add an extra CMS sub to make it 7.2 or 5.2.
7.1 SETUP
LOOKING FOR THE "BEST" SPEAKER PACKAGE MAINLY FOR HT USE. WILL BE USING BIG BOX RECEIVER BUT LIKELY WILL ADD GOOD AMP IN TIME AND USE RECEIVER AS PROCESSOR ONLY. BUDGET FOR SPEAKERS IS APPROX $5000 PLUS SUB BUT THAT'S NOT SET IN STONE. LOOKING AT APERION, ASCEND, ETC. INTERESTED IN USER SUGGESTIONS. ROOM IS RECTANGLE 20L X 13W X 9H. WILL USE FOR 2 CHANNEL AS WELL BUT ONLY WITH SONOS SO SUPER REVEALING ISN'T HUGE ISSUE. LOOKED INTO SALK AS WELL BUT PRICING ON THE WEBSITE IS TOUGH TO FIGURE. THX IN ADVANCE.
