Sony XA5400ES lack of bass when new?

"Nothing" below 100hz was an exaggeration but meant insufficient.
The bass is better after 24 hours but will check my connnections.
Otherwise I had a SCD-1 for 9 years & the 5400 is tighter + more musical.
Like a window into the recording session

Are you using HDMI outputs or analog outputs, or a digital output? If HDMI, check that your Priority switch is in the 2 channel position.

Like many others here, I have found the Sony 5400es to have appropriate levels of deep bass right out of the box. However, its bass definition is not as good as that of my Cary Xciter DAC (using the Sony as a transport via a 0.5 meter coax cable). I suppose my Sony is still in its break-in period (thanks, Metalla and Bigtee, for hope that the Sony's bass definition will improve). But it's an excellent RBCD and SACD player overall, and a bargain.

Analog outputs in 2 Channel position.
I checked the back

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.
