Cyrus quality audio is now available to everyone.

4/5
,

Although the DAC chip has been upgraded to a much more expensive one ($25 vs $10 in sample quantities), there is little, if anything, to show for the effort in terms of measured performance.

I see it a step up from $9 dongles but the $99 price is hard to swallow.
