It is with great sadness that I report this is proving to be 100% true.
I've been testing normal CDs and SACDs for the past couple of days using my old Wadia CD player from 1998, along with a friend's 18k Esoteric SACD stack. The results aren't even close; SACDs, and in some cases regular CDs, seem to destroy streamed and locally stored digital files quite handily. The staging and imaging in particular are so much better and things tend to sound a bit "tighter" overall. Streamed files especially felt quite "flat" and 2-dimensional by comparison.
The obvious problems are that SACD seems to be a dead/dying format, while streaming is quite the opposite. Streaming is also infinitely more convenient. Are there any SACD lovers out there that can speak to sourcing and availability of modern releases? Do labels still make SACDs? Buying into SACD as a format seems more than a bit foolish at this point, but the bump in both quality and performance is undeniable.
Needless to say, I'm going to stay far away from vinyl. CDs seem to be a better "middle ground" choice.
