I haven't heard this particular Sony, but I have two thoughts to add: ONE, ModWright really loves this player and calls it the best SACD player he has modded yet. Unlike the Sony 9100ES, which is DVD / SACD, the circuitry in the 5400 is relatively simple (being audio only) and consequently lends itself to better sound quality. (I own the ModWright / Sony 9100ES Platinum Signature Truth mod and will use it until it's dead. By the way, the chassis for the two players is virtually identical, and is one Sony has been "re-stuffing" for some time now.) ModWright is the way to go for ultimate upgrades, IMO.
My SECOND thought is this: As good as Sony's best SACD machines are (modded or not), they all possess one annoying feature: VERY SLOW disc read times...sometimes a minute or more on certain discs! There are other fine players out there which use an entirely different transport--the Philips CD Pro 12 series, which is VERY FAST. Musical fidelity, Jolida, and Shanling are a few names that come to mind, if memory serves. And don't forget the Oppo SE, which plays EVERYTHING and is nearly in the same league as the new Sony for considerably less money...and its operation is LIGHTNING QUICK, from what I understand. (ModWright upgrades this player as well.) When I put a disc in the drawer of my Sony, I think about things like the preparation time for a good meal, which helps tame my frustration considerably... ;)
