Just guessing I suspect Monster amps were designed by Richard Marsh who also has something to say about their power conditioners. Imo they're overpriced but to each their own. For those who don't know Richard Marsh has been a highly respected engineer for decades.
One thing you also have to remember that after all the attention Monster received regarding their lawsuits against small companies that they lost alot of their respect. I will never buy anything from Monster again no matter what the deal is, even free.
