Seems like you haven't been over to the ER forum and read about how the product works. It is not a buffer. But go see for yourself. -I wondered if this product could make much of a difference in my system but it is a pretty amazing change. Can be heard by anyone. BTW, my streamer fully buffers each and every track and wow, what a difference with the ER. Natural, 3D, musical, etc. Across the board better. Just a massive positive difference. You can see my review over on AS. I couldn't imagine listening without it now. It is easily the best $640 I've spent in audio after three decades of being involved in this hobby.
