The Yggy can have a direct coupled analog output and still have its SQ changed with replacing those WIMA caps.
R2R DACs requires a post anti-imaging filter to remove the oversampled garbage from intermodulating the signal. That filter would use quality caps in either shunt and/or NFB positions to perform this task. Technically, not in the signal path, but would still influence the SQ to some extent.
I have an email of inquiry into Chris at Parts Connexion and may be trying this mod myself soon.
