FWIW, 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 have a Lynx II that replaced an Echo Gina 24. The Lynx sounds much
better than the Gina ever did. However, I've owned two Echo cards and
they have been rock solid performers. Great drivers and support when
I asked for it. The lynx
just sounds better. FWIW, I use the Lynx ASIO drivers in Sonar 4.
Lynx doesn't have a production WDM driver yet.
