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???

"According to Wadia, it was designed to be left on all the time."

Try leaving it on for a few days. It will sound better.

I leave it on most of the time. I turn it off when cleaning, electrical storms, etc.
I am driving my LS50s with a NAD d7050. I am not very experienced in audiophile systems but what I can say is that my system is sounding better than ever. In addition, although the d7050 does not have any analog inputs, it is very versatile when it comes to connectivity to digital sources. I find it a great option for one shopping for a power dac.
