SACD or not

SACD can be great but BluRay audio is better I believe, if done well.

Even if you don't plan to purchase SACDs, if you get a deck that supports that format, the built in DAC will probably need to be of higher quality, in order to decode the DSD content on the SACDs.  When I was early in my journey to the higher end hardware, I purchased an NAD player and the detail I heard extracted from that unit, on "regular" CDs, was noticeably better, as a result of having a better DAC chip in the unit.

Agree that Cary 306's or Pro's are still great players for Redbook CD. PS Audio Directstream may be the best value in two box systems for either SACD or Redbook CD for the money else you start venturing into EMM Labs or Esoteric costs(>$10K). 

I do not know what type of music you like. I think that most albums is with classic genre.
But having a player that supports the most formats is maybe a wise decision.
There is the optimal and the best format HRx.

All the different formats as CD, HDCD, SACD, HRx, DVD-Audio, BD-Audio. All the albums may have any but are not on all of the formats. Let that be the limited factor..
So if you have a player that is playing all formats then you can pick the best sounding format that is available for a specific album. 

That will certainly sound better than a little better player that you are forced to choose a suboptimal format become your new player can not play the best sounding format that were available for that album.

In other words a standard player that play a album on SACD. Will sound better than a super duper player that can not play SACD and force you to play CD..

There is the optimal and the best format HRx.

I believe there is even better PCM, that’s DXD but you need a good R2R based dac to extract the best from it, not a DS based dac (that will do SACD which is flagged DSD)
