Cost and product are immaterial. Amir’s point is being made regarding all such devices. Until or unless you post something more meaningful than links to Amazon reviews and more conjecture videos or personal subjective experience, nobody here will take you seriously.\nSo, yes, we will continue to disagree.\nI, along with many others, will continue to look at the science of it and rely on the words of true engineers rather than any random person making such claims.\nWhile there are sites you can get accolades for preaching the amaze-ball differences you think you experience, places like AH and ASR really don’t cater to that crowd. Not when we have actual engineers showing us what happens when similar items you have espoused are inserted into the chain (be it from wall outlet or wherever).\n\nThats it. It is that simple. If you bring something meaningful to the table you will find a different experience here.\nIn fact, since you have such an interest in these items and have recommended them in many threads, why not send them to Amir to test for you! They are your claims and the burden of proof is on you. So try it: beat us at our own game. ;)\n\nCheers.\n\n\nIt seems you have made up your mind and that is fine. I, along with many others who actually try different products, keep the best and return the rest. If you choose not to why would I possibly care?
