My experience with Sonos is that they are ok at moderate volumes, but when cranked up there is a noticeable "midrange hole" due to the smiley shaped EQ curve. OTOH, I doubt the Energy TC is that much better to begin with, given their small size.I currently have a energy take classic 5.1 in a small bedroom hooked up to a Marantz receiver. It sounds pretty good given the less than ideal arrangement of the room, but I've been toying with the idea of switching over to a Sonos 5.1 setup by adding the Sonos ARC and Sub. Reason for doing so would be to reduce wire clutter as I can't go in the wall and (more importantly) reduce the heat coming from the Marantz which makes my room somewhat uncomfortable in the summer.
Cost isn't an issue here. Even if I keep the classic 5.1 speakers I'll need to upgrade the Marantz to something that supports HDMI 2.1 as I have both of the new consoles and a Sony X90J that supports HDMI 2.1. That new receiver is going to be expensive. I can probably live without DTS since the ARC from what I understand supports LPCM 5.1.
The biggest downside would be having to find a quality HDMI switcher with HDMI 2.1. Also, while I like how the Sonos Ones sound with music, I can't find any reviews from sites directly compare how a small, well reviewed satellite speaker system like the classic 5.1 compares to the Sonos 5.1 for regular TV watching, gaming, and movies. I mean RTINGS does comparisons, but I was looking for something from a more A/V enthusiast perspective.
Any advice would be greatly appreciated. Thanks.
