Why is top quality expected here? These are mass consumer products. They will never achieve high quality. It is produced quickly and has to be cheap.
I personally don't think that at its initial $6000 price tag this is a mass consumer product. It might be engineered that way, but for that price I would at least think I buy an upper mid-fi, audiophile product.
In my mind a mass consumer product would be something like the Yamaha HTR-2071 for 199 pounds.
Thanks to this website we all know that there is probably not a big difference between the two.
