Sony XA-5400es player...Giant Killer or just Ok?

As mentioned, this has been hashed over many times but if you're going unmodified and listen mostly to redbook, I'd go with an Oppo 95. The Sony is probably better on SACD but I'm guessing redbook will be your main diet. Of course with the Oppo, you also get video.

If you're considering the Modwright route down the road and audio is your main concern, I'd definitely go with the Sony.

Missioncoonery, JWM owned both the Sony & Oppo. I currently own both. Alpha3 was asking for opinions on the Sony and JWM was just trying to provide a bit more info on a competing player that is often chosen over the Sony; so what's your problem?

As for resale value of modded players, there's some truth to what you say, but Dan Wright isn't just a modder. He manufactures a very good line of equipment and has a great reputation with his customers. I'd wager a Modwright player will hold it's value far better than most of the other "crap" listed on this website, particularly the mega-buck players that plummet in value almost immediately and often sound mediocre compared to one of the Modwright players.
