Yep. Most of your comments are correct. Though you can open up the Sbooster and can have a look what's in there. The Sbooster is pretty basic, that's correct. Though it's not a "simple cap filter". That would be a first order filter. It's a 2nd order lowpass. It's pretty much the same setting as John's setup. The Sbooster IMO is not expensive. And best of all -- it works. Howard mentioned "large improvement". And yes, John is always careful to avoid not to bet put into the snakeoil-fraction corner. And that usually happens over here immediately as soon as you can't show "measurements" or scientific explanations. But meanwhile we know that even if measurements are made and effects are proven quite some ignorant people around here tend to spread the "old" snakeoil message. I don't have a problem with that. I know what I hear.
