I have used the previously model of Sony, the XB820, for near 9 years until now, and it's a good player,with delicate treble,great midrange and decent bass.
Good the detail too, but not so much.
A warm and full body soundstage.
The three filters change the sound in a almost inaudible way, thought the filter nø3 is the "warmer", and the first one is the "more open".
It's still working, but from 2 days ago i repleced it with a new player, the Nad c565...
I could not believe to my ears...it's like night and day...the Nad is 10 times better than old Sony , in every music-aspect...
Simply stunning player, for detail,presence, voice,bass,dinamic...maybe just a little less-thin body...but great soundstage anyway.
And is pratically "out of box", just 3 hours of burn-in from yesterday...
But structurally Nad is obviously more delicate and "fragile" than Sony,that is really a tank...in 9 years never a problem... never.
So...If you like a delicate,no tiring and full sound, take the Sony, it's still a good player.
But it's correct to let you know that today there are many players ( more expansive, of course) that outclass the Sony.
