yes. This is documented at:
http://eca.cx/ecasound/features.php#what_worst
""Bitwise File Conversions
Before processing, Ecasound converts all input data to its internal
format (defaults to 32bit-float/44100Hz). This is not optimal if you want
to perform bitwise conversions from one audio file format to another.
Work around: Better tools for this kind of work are Sox and
libsndfile tool sndfile-convert. ""

So the differences should not be audible significant, but if you need
bit-accurate conversions, better use other tools.
