++++1 on redbook as I've written above.
OTOH in my experience higher rez takes a step up from there depending on the native resolution of the file. I have likely 12 terabytes of higher rez (PCM and dsd) and it is 'better' than redbook in general. but I've not done enough comparisons to get specific quite yet. and you can throw MQA into the mix and there are many truths to uncover.
maybe the hype part is that redbook is deficient in some way; it turns out the that it's the implementation of the hardware when playing redbook that can be deficient, not the format.
I also thought that the 'dsd Optimizer' is a no-brainer. Vince demonstrated it at the L.A. Show and it was easy to pick up on as an obvious step up. my Select II came with the Optimizer selected and I've not yet got far enough to even try it 'native'. maybe at some point I will and then will try to quantitate the differences.
By the way, I notice you got blue LEDs. I got yellow, I guess to go with the gold parts. After we both have our systems dialed in, we will need to compare blue v yellow. Just kidding.
