Though I have no experience with it, but the price and specs look interesting enough for the money. However, if I search to Axas E4HD 4K Ultra HD review, it seems like a bad buy to me.
Nowhere, but when I see/read some reviews and ratings, it doesn't seem like a good purchase in my opinion. Nevertheless, that is my impression of it, I do not own this receiver to give a good impression of this receiver.
