I am not familiar with the SACD players you mentioned. I am aware that newer SACD players out there do have some bass management functions that earlier SACD players didn't have. And I believe the newer receivers especially from mid-to-flagships models from Onkyo, Denon and Yamaha, do have bass management for DVD-A and SACD.
But I've seen some work-arounds on earlier SACD players and HT receivers that don't have this feature. Either they use an Outlaw ICBM or a dbx sub-harmonic crossover unit to bleed out the bass from either multichannel (outlaw) or stereo (dbx). I don't know how the Outlaw works but the dbx sub-harmonic crossover takes the stereo analog signal from your SACD player, extracting the bass data at either 120hz or 80hz crossover point from both channels, and routes them to a powered subwoofer. You then connect its high-passed L and R channels to your receiver or preamp.
