I can't understand all this hype about Wyred 4 Sound. I have tested the Dac 2, quite good but nothing exceptionnal for the price.. Amps like the Wyred 4 sound SX 1000 are just boring, flat, undetailed, lacking of everything. In one word: uninteresting at all.
I have compared them to two sono amps.. Sono amps were a lot better.. If you want to know what sort of sound you can get from a Wyred 4 sound SX 1000 in comparison with a sono amp, just take a pillow and put it on your loudspeakers.
So when you speak about high-fidelity, please stop mentionning Wyred 4 sound.. Even entry level sono products make better.
