Sony XA5400ES lack of bass when new?


I just recieved this player from American Theater & set it up.
I know it has to break in of course but the lack of bass is surprising. (Nothing below 100hz)
Is this normal for a new unit and approx.how many hours to hear an improvement.
Other than that it sounds pretty good.

I also had an SCD-1. The 5400 outclasses it in every way except cosmetically. The SCD-1 is one of the finest looking pieces of audio jewelry I've yet to lay eyes on. Is anybody running XLR interconnects on their Sony 5400es? Was wondering if this player was a fully balanced unit. Don't see it advertised as such. I guess it would be a no brainer if it was. Just curious if anybody could give a little insight.
It appears that your unit may have been defective. Why didn't you return it for another one?
