Their analog circuitry around it is good and
Well, the analog frontend is in fact the most critical component and the
one that requires most knowhow and enables RME to put out rather
complete specification. In comparrison at least.
F.e. I have not seen too many soundcards around that provide frequency
response as data, at least for selected products, though I happily stand
corrected - I am not married to RME at all and welcome alternatives.
Lynx does so as well, but has no linux support afaik. Haven't checked
focusrite f.e.
Wether this data matters or not, may be up for debate and numbers make
no sound, but it should be mentioned.
