My living room is all SVS kit: a single SB13-Ultra (their older generation 13" sub), ultra center, 2x ultra towers, 2x ultra surrounds, 2x ultra bookshelves in the rear, powered through an Outlaw 7700, eq'd with a MiniDSP DDRC-88a, which is fed by the multichannel analog output from my Oppo UDP-205 at the center of the system. I feed a cheap aliexpress HDMI switch into that as my source selector, and have another headphone amp (a Gustard H20, which is a little too large to ship to Amir, unfortunately) hanging off of it for late-night 2-channel listening lest I get evicted.
I'm incredibly happy with SVS' stuff, particularly the towers; it's well-built and gorgeous (I love me some piano gloss black), and all of my dealings with support have been phenomenal. I ordered everything direct from them, so I don't have a clue what support looks like when buying through best buy (I had no idea they were selling through another channel now).
That said, my "I'm happy with it" is purely subjective, and I have no measurements to share. (I can make one comment about the amp though: there's no gain control, and the noise floor is clear as a bell in all speakers with the DDRC-88a connected to it, without additional attenuation. That was a fun discovery after plunking down on shipping it to the US.)
