Streamer suggestions with both wireless and wired connections

I am using a Blue sound Nide 2i streamer (not as a dac though) for already several years, sometimes I use my computer and actually I note no essential difference in sound quality.

This begs the question, what music service are you using and what’s in the rest of your system because this flies far in the face of the experience of the vast majority of members here.  Put another way and more directly, something seems really amiss here.  The more info you provide here the better and more meaningful help and recommendations you’ll receive, so please share more if you’re willing. 

Some time ago I bough a Chinese  clone of a very expensive Swiss amp. The clone is claimed to perform 99% as the original one and it costed about 15 times less than the cheapest amp I had before…According to the info I have, the parts are not cheap, however the amp is cheap. Does Aurender use extra super expensive parts to charge so much for their streamers, or does it have an exceptional design/patent that makes their streamers so expensive?

Well, good for you.  How can you confirm the internal parts aren’t cheap crap and will hold up over time?  You’re just gonna trust the word of some Chinese knockoff product company?  If something goes wrong how will you get the amp serviced?  Aurender has an excellent reputation and makes some of the best-performing streamers extant, which speaks for itself.  I suppose you can maybe try to buy a cheap clone of an Aurender as well, but good luck with that and with your cheap Swiss-clone amp.  You roll the dice and you take your chances.  To each his own.
