I am looking at purchasing the Martin Logan Dynamo 800x or the SVS SB 1000. They are almost the same price. Which would be the better sub? My room is 18 x 12 feet, acoustically treated. I am running a Rogue audio Sphinx amp with an anti cables level 3 power cord, Martin Logan ESL speakers, Audio quest William tell speaker cables, Blue sound vault streamer and an Arcam DAC. Thanks
