I suspect that reflections and resonances are a larger reason for the low-ish null numbers.
Plus it’s raining today
Better to ignore. DSD is like MQA, only less lossy and just as inconvenient
As the owner of the SA-10, my recommendation is as follows.
1) Do you have an existing SACD library?
No —> stop. You are done. Do not buy a SACD player.
Yes —> is your current SACD player broken? If not, do not buy another SACD player.
2) Do you enjoy physical media and “unplugging” over a local DLNA server?
No —> stop. You are done. Buy a used Sony Blu-Ray player and extract your SACD collection to a network attached storage
Yes —> you might want a SACD player
3) Are you OK listening to your physical SACDs on your home theater system?
Yes —> stop. You are done. Get a Sony BD or UHD disc player which will transcode DSD to PCM over HDMI with “Sony approved” algorithms
No —> you might want a SACD player.
4) Do you like vinyl LP playback?
Yes —> you should probably get a SACD player because you enjoy anachronisms and experience more than pure sound quality.
No —> You should sell your SACD collection. You won’t miss it.
