yeah... sort of
a couple reasons
the E9 I got a steep discount +$40 off
and I have a T-AMP that lacks headphone out..so I was having to use a 3.5mm splitter which was not ideal (cause I had one more cable in the mix and had to unplug the headphones or live with a loss of signal level to the speakers when I wanted speakers
now going XonarDG to E9 and Line out to SA-S3
may be my imagination but my AD700s and the RX700s seem to benfit sound wise from the amp to my ears.
meh.. more convenient and super low price on teh E9 == WIN! (granting that I didn't really entirely need it for my current headphones.)
