Power DAC for KEF LS50


Need advice : I bought a pair of LS50s. I want to stream my large Apple lossless library using my Sonos Connect. Need advice on powerDAC under $1000. What is the best option for these speakers? Peachtree Decco, Nuforce DDA-100, Parasound Z series, Wadia mini, other ideas???

I had some LS50's and had run them at various times with the DDA-100 and little Wadia 151. It worked well with both, but I think the Nuforce was a little better having a bit more power.
I thing the ls50's will do best with 100w/ch or more from a more beefy amp with good current delivery capabilities.

A quality Class D integrated from a reputable maker is probably where I would look for most bang/buck.

Rogue Sphinx hybrid Class D integrated might be the the first option I would consider were it me.

Parasound is also quite highly regarded for performance and value as well. PRobably could not go wrong there either if a pure SS integrated is preferred.
The KEF LS50 is affordable but I am always amazed at how good it sounds even when paired with components outside its price range. I have heard improvements going from a Bel Canto REF500M to a Plinius SA-Reference.

But for me, the sweet spot would be something like a Bel Canto C7R or a similar mInt from Wyred4Sound - if you need an all in one DAC and power amp.
