In general I have always liked the cd layer of SACD's better than the SACD layer. Just my opinion
I have not heard the SA14S1 but did have its little brother SA8005 in my home for a demo recently.
If you are worried about midbass and a slightly rolled off top end then I'm not sure Marantz (assuming the 14S1 and 8005 have the same house sound) is the right answer.
It was those very qualities that prevented me from buying the Marantz. I'm running KEF104.2 (tweeters restored) with a Modwright integrated.
Many others would disagree so I recommend trying a Marantz (or any other player for that matter) in your system first to ensure a satisfactory match.
Right out of the box the Oppo 105 is the player to have modded, the Oppo 95 does not have the direct audio path circuitry designed for high end 2 channel sound, using the ESS sabre dacs in dual configuration going to either specific XLR or RCA outputs. The 105 is the only OPPO for high end audio consideration. So to clarify, the Oppo 105 costs $1200 new and sounds way better right out of the box than any of the suggestions given hear so far. You can’t buy a better sounding player used or new for $2500. Then when you really want to raise its performance up several levels more, you can have it modded by Modwright (around $2000). The 105 uses the same dac’s as other way more expensive units do. It is the best deal in universal players for yesterday, today and tomorrow.
I would work with speaker placement before I did anything. Maybe get them a bit further from the wall or change the stands or the way they are coupled to the stands. A harder footer could clean up the midbass and a bit more toe-in could result in more treble energy reaching your ears. I don't think an SACD player will fix what your are describing.
Thanks for your response. Perhaps my question was a bit unclear. I am not looking for a SACD player to fix anything. I am looking for a player that has CD and hopefully SACD playback that has sonic characteristics unlike the Saturn. SACD playback would be a bonus. The Saturn is a very fine player, just not the best for my system, to my ears. I have worked with speaker placement, toe in, and stand set up.
How do you know it is the Saturn that is causing the sonic issues you claim to be having? Have you tried another CD player? That's what I was saying. It's an unfortunate thing that, IMO, based on owning a Sony 5400, 9000 and an Esoteric X-5, the Redbook is not up to the level of similarly priced dedicated CD players. Maybe if you're getting up to the higher-end players in the $10k+ range, the CD playback is better, but it's been lacking in all the ones I've tried. Maybe you should just look for a used Sony 9000, which has excellent SACD playback and use it only for that. The 5400 has better CD playback than the 9000, but it's not nearly as nicely made and the CD playback is not all that great either - just better than the 9000. Good luck.
