SACD

I am one of those who went away from SACD. They sound good when the whole recording chain was done via SACD. Unfortunately, there are a few audiophile records, most is unimportant.
The Majority of SACD use the 44.1 master and it is converted to SACD. Most sound clear but sterile/boring.
Maybe (or for sure) I am a minority, had SACD Player, sold it and the one in use is for regular CD only. From my experience, the best sounding CD’s are those which were made in the 90’s, at the beginning of the Digital Hype. Most Studios still had - some - analog units in the mastering chain (AAD).
There are endless cheap 2. hand CD’s available, you can buy a dozen for small money and when you really like one or the other you can look for the expensive SACD. I did it that way at the end.
What is generally very good, imo better, is XRCD from Japan.

@jimmycg,Sorry for your loss. I can very well imaging what you must be going through. A few days back, a pipe from the mains to the whole house humidifier developed a pinhole leak and an unfinished portion of my basement had a bit of water. That was scary enough for me.Like most of the posters said - it depends on the mastering process. I have a few SACDs that I enjoy. Whenever possible, I try to get the SACD instead of the CD. Acoustic Sounds produces good SACDs and new ones keep coming. Get a player that plays SACD as well as acts as a DAC for DSD files. So you now necessarily have to buy SACDs. Instead download the DSD files. I like my SACDs and enjoy them. If you like your SACDs and can get a SACD player, got for it. Let the other posters not detract you.
A tip that I would like to share - when ever you go on vacations, or even a 2 day trip, shut off the water mains. Then drain all water from any one outlet in the sink, bathroom, kitchen, wherever.

Was just researching the same...

Out of 350 discs I have 42 with layers that won't play on a red book only CD player. (That number may go up sharply now that I've found Dutton Vocalion, who sells SACDs for $20 here https://www.duttonvocalion.co.uk/ and on Amazon) Of those 42 there are perhaps 5 that sound no better to me than the red book layer and only one that actually sounds better in red book. That makes a universal player a must for me. On some, Beck - Sea Change, Norah Jones - Come Away With Me, Jennifer Warnes  - The Hunter, Neil Young's Greatest Hits (DVD-A) for example, the difference is breathtaking.

I am using an Oppo BDP-95 in my main system. I still have my first UP, an Oppo DV-980H. They are quite good for the money. I replaced it in my smaller system with an Oppo DV-983H, which is awesome for the money; but only come up rarely. I'll be selling the 980 now, but I wouldn't post it here, where people post asking "What's the best DAC for red book in the $15,000 to $20,000 range." I don't think many would even read an ad for a sub-$100 UP. I am not judging; I'm just not in that league....yet. ;^)
