SACD Player/Transport Choices

I am planning to acquire a McIntosh MCT500 to go with my C53 (proprietary MCT connection).  But I am wondering if there are other good SACD transport choices that will send a true DSD stream to an external DAC on a non-proprietary basis, either through USB or I2S.  I’m trying to research this, but it’s difficult to find definitive answers regarding the actual digital stream from SACD - often I discover that the stream is converted to PCM.  I do know PSAudio has a scheme similar to McIntosh.

I realize simply purchasing DSD and streaming from an SSD is probably more practical these days.  But I am sort of fixated on a physical disc player.  Budget-wise, most interested in transports around or below that of the MCT500 (~$5K). Thanks for your thoughts and advice.
