Santa obviously didn't deliver a sense of humour!
I've tried Zilplex and Mooks. Both are useless.
I am afraid I get very tired of these lets slag and take the piss out of comments put forward by folks who haven't actually tried the thing they are taking the piss out of. Yes on the face of it looks like a nice piece of art, rather than something that might effect sound, but I haven't tried it so can offer no opinion. However I have heard something that might share a similar design ethic and it did make an improvement.
Oh no no no.... can't be doing anything like that :D
Obviously no matter what/how it sounds one thing it isn't is adding to the accuracy of the reproduced sound and so it is a bad thing.... even if it sounds "good".
It never ceases to amaze me the crackpot ideas some will try and foist on the world of audio... maybe that Buddhist bowl could hold snake oil though... a dab behind the ears before listening....
It's not a piece of Hi-Fi equipment and there's no way it can add 'fidelity'!
I would think all it can do is react with/agin the soundwaves from the speakers. either adding to or transforming soundwaves. Fair chance its audible, although I am thinking its unlikely to be in a good way on paper. Might sound enough different to give a pleasant effect though to some.
It's a bronze bowl on a stand and it costs over two thousand dollars. Even if it does 'do something' it is still priced outrageously. And I don't want to hear any bollocks about paying for the R&D. Someone who is loaded buy one and we'll pass it around, I'd give it a go. Thing is, even if it does work all it can do is alter the room acoustic and there are a million ways to do that that don't cost the thick end of two large.
