I've had the Sony XA5400ES about 7-8 months.
I've been using it with an Onkyo 876 HT receiver.
I used it for some months with a Cambridge 840W/840E combo
before selling the Cambridge.
The Sony has a problem starting discs from 00:00 unless you leave the disc tray open and press the "Play" button on the remote control. It skips a second of the program if the tray is closed when you press play.
The remote is cheap and, despite having plenty of free "real estate", they make the play button the same size as pause and stop.
Another thing I don't like is that you must press the power button before you can use any functions.
My previous (Sony) SACD player ($215) would power-up automatically when you press the "Tray Open" button, etc.
The sound is very dynamic (CD and SACD) and certainly does nothing "wrong", but does not have the "cut above" Blue-Ribbon sound I remember from my Rega Apollo/BAT 300X-SE system (lacks soundstage pecision and the feeling that you're getting 99.9% of what is on the disc. Musicallity also comes up short).
I'm doing my best to re-acquire the BAT and I'll give you an update when this happens.
