SACD vs. Redbook with NOS DAC

Silly question? Maybe not. I've been really enjoying the SACD format for some time. Relatively recently, I've been exposed to NOS DACs and have found there are a LOT of similarities: smoothness. They both sound like analog!!

So, now I'm at a point where I'm considering dumping my SACDP for a computer-based system with NOS/filterless DAC. I was just wondering if others have gone this very same route and have thoughts to share?
