You have too many variables!
From what I know, SACD technology has not changed a lot. It is still at 100hz, while cd players are easily at 24/192.
So, a high end older SACD would be fine, you have to use analog outputs on it any way. On the other hand, a new tube based cd could be tremendous.
What would I do in your shoes? Buy a really nice several year old SACD player for a really good price. Then, get a much newer tube based DAC to run the digital cd outputs to. You now have two completely different players with only 1 transport.
This is where you can save a small fortune on buying a modded SACD player...
