8th Nerve came to my house and did a complete room test with thousands of dollars of equipment. I bought a couple hundred bucks of their stuff but to pay someone to do the same thing would cost twice as much as the product. I'm not saying they always do this, it worked out for both of us but... clearly 8th is my choice.
Since there's clearly some kind of lawsuit issue, I would imagine the essential design and construction are similar. Otherwise, the products would be different enough not to have a dispute.
Based on MG's behavior on this forum, I wouldn't do business with them but it's your dime, not mine.
