2 for 1 or the PS Audio upgrade route?

Thank you for the first hand experience. The Marantz seems to be a solid unit based upon what I’ve read. 

SACD, I suppose, is required. Currently own 2 or 3 of them. Listen to them once or twice a year. It’s tough to lay down 20$ and up for one SACD when cds are essentially being given away for pennies on the dollar. 

Thanks everyone for the responses. This situation took an odd turn as a Sonic Frontiers unit with PCX upgrades performed in 2103 and 2020 became available. So, without hesitation, I purchased the updated SFCD-1. It is a super good unit. The only downside to this unit is recordings that are awful, stay awful. It does not sugar coat lackluster recordings to make them listenable. 
 

Along the way another CD player became available. An American Audio Labs P-11. This is a modified Magnavox CDB-560. After some TLC, the unit is up and running. This P-11 is also an incredible sounding unit. 

So, for now, it looks like I’m standing pat with the units at my disposal. They may not be the best of the best or the latest and the greatest yet, to me, the law of diminishing returns has unequivocally kicked in. Perhaps in the future a mega dollar unit will be pursued. However, for now, the lower dollar units are here to stay.
