Wavelength Cosecant or TwinDAC+ or ???


I'm sure that there will be lots of USB DACs on the market very soon. For now, however, it seems that the Wavelength Cosecant or TwinDAC+ are the two best options. Has anyone A/B'd both in the same system?

I had the Wavelength Cosecant DAC in my system but it was out performed by the Audio Logic, Chord and a few others in the same price range. It lacked the dynamics and deep base of the other units I compared it to.

Happy Listening.
There is also now the Chime USB tube DAC. Takes regular input too, volume control.
