"Why not look at the analog section of the dac as well? I think you’ll find all the players mentioned use dac data textbook I/V stage and output stages, which are just opamps."
I’ve owned 3 of the players on the OP’s list and I have a fair amount of time with 2 others. They all sound different. Audio is hands on. If you want good sound you have to be proactive. That means listening to as much gear as you can. If you make buying decisions based on spec sheets, that’s what your system will sound like. A spec sheet.
This is why most of the one mentioned have text book I/V and analogue stages, nothing special.
But if you really want to be hands on and have the ability, you can do a far better feedback free I/V stage and better output buffer than these text book ones that OP is choosing between.
Here is a link I started over at DiyAudio on a better I/V stage for dacs and cdp's which gives a far better sound than the text book stuff.
