Problems with the IFI Zen Stream.. What's a better Alternative?


I own two Zen Streams  and use them in different systems. I have used them for approximately two years. On the positive side they both deliver excellent sound quality. The problem is, as of the last few months, they both drop the network signal frequently for seconds to minutes. The red light comes on, then goes back to green. They are both running through ethernet cable, not wirelessly. After hours of trouble shooting, I have concluded that the problem is with the streamer, not something else. I suspect they might be failing due to the heat they generate. That's just a guess. 

My question is: what produces of similar or better sound quality with better reliability new or used? I would like to stay under $1,000.

@cagma7 First I used the upgraded ifi ps. Later, in my Florida system I upgraded to lps unit I bought on ebay. In the summer house setup, that I have been comparing with the Ultrarendu,  I use a Topping P50 Linear Power Supply. The Ultrarendu uses the lps currently  supplied by Small Green Computer.
