If you don't have facts it would be a good idea to stay silent -- you are fully entitled to your own opinion, of course, but if you share it in public then expect to be disagreed with by those with facts. Fact is... Sundown Audio hasn't been growing significantly every year since we started because we make junk products. We spend almost zero dollars on advertising so guess what keeps the growth moving along ? Word of mouth from satisfied customers.
If you don't like the product that is more than fine with me, though, plenty of good choices out there on the market. But I'd suggest not making erroneous and ill informed statements such as that "all" of our amps break.
PS: "S" shaped surround has been done. A.D.I. has a technology called RevSurround that also flattens the compliance curve.
