DAC and power supply much more important determinants of sound than anything @jasonbourne52 cites.
I’ve heard both SACD players, and I’ve heard the OP speakers. However, I haven’t heard them all together, nor have I been in the OP listening room. Although I disagree with everything else in @jasonbourne52 post, he is ultimately correct in that both SACD players will sound good. I agree with poster who said the Denon will sound a bit darker than the brighter Yamaha will sound. Personally I would prefer that, but ymmv. The speakers aren’t particularly treble happy, so even the brighter Yamaha won’t lacerate your ears.
