Marantz SA-10 arriving Monday!

Thank you, Elizabeth and Blueranger! I know exactly what you are talking about. However, in my system, the only two new changes are the SA10 replacing the XA5400ES and the addition of an aluminum/carbon outlet frame on the main outlet. I installed the dedicated line 7 years ago and terminated it at the time with an Oyaide R1 cryo outlet. That outlet powers two Furman Reference PCs, one for the amp, preamp, and CDP, and one for the subwoofer and some video components.
The other thing I can think of is that the SA10’s output level is higher than the Sony’s, so the preamp volume is now in a different range than it used to be (and that may mean for Luxman’s LECUA that it uses electronics/paths that have not been used much); still, I do not remember this type of brightness when the preamp was breaking in.

Thank You for the updates- astru
blueranger and Elizabeth.  Hope you guys are well and enjoying your SA-10.  Happy Listening!

It will be the last SACD player I buy.

With the Oyaide frame (bought on eBay from Japan and possibly fake) out, most of the brightness is gone. Jacintha's Moon River and Here's To Life became enjoyable again, for example. However, I hope the SA10 still needs break-in because her voice is not as in-the-room/unplugged as with the Sony. Everything else is arguably better, from pinpoint imagining to instruments being more fleshed out and more natural sounding, with better decays. I just need female vocals to become a tad more natural sounding to love this player.

I have had mine a month and yours will continue to resolve more details and place more air around the instruments. Enjoy
