I can see the argument for buying an SACD player since there are more options on disc form but they’re expensive
Your DAC already has DSD capability, so all you really need is something that acts as an SACD transport, that is to say, no analogue output is needed. Sony make a universal disk player, the UBP-X700U, which you can probably buy new for under US$200. That’s right, only two zeros.
It only outputs over HDMI - one is dedicated for audio. So if your DAC accepts HDMI natively (not I2S using an HDMI cable) that’s all you really need.
This transport is not built like a tank, but it supports Blu-Ray up to 4K, SACD, DVD and CD. Apart from SACD, it supports other high resolution audio formats including Pure Audio Blu-Ray and Dolby Atmos.
If you are into classical music or jazz, Presto Music | All things musical… on your doorstep has over 6,000 new SACD titles listed. They also have a streaming service which offers downloads at no extra charge.
By the way, DSD on SACD takes samples 64 times more often that CDs, so it is often written DSD64. You DAC does even better at DSD256 while your transport is probably DSD128 capable. But for SACD you only need DSD64.
