I have the Lynx Two and previously owned the Echo Layla 20. That's
not really a fair comparison because the newer Layla is probably better, but
I certainly have been very happy with the sound quality of the Lynx Two.

I have had frequent problems with Windows drivers for both though, which can
really be maddening. I would rate the hardware for Lynx A+ and for Layla B.
I would rate the software driver support for both companies a D.

I bought my RME Digiface primarily for the quality of its drivers & support. I have not been disappointed.
