Understood. I just did a bunch of reading over the past few days, including right here in the Sound Science section. Indeed, your assertion is correct and I can see the information and research that speaks to this topic. Very fascinating and clearly, I can save a ton of money by sticking with 16/44.1 ALAC files that I already own. Reading up on this thread and the sound science topic has been quite illuminating.
That being said, look what Mr. Fed Ex man brought me this afternoon:
I'm typing now and getting my first dose of the RME ADI-2 FS, listening to some prog rock. Whoa, I'm beyond impressed right now. No real words to quantify this initial voyage, but I'm absolutely loving the detail and clarity.
My next quest is to upgrade my headphones. I used to have some HD800, but sold those a while back, not caring for the treble response. I'm currently listening with headphones that I normally use for recording musical instruments which I think are simply just OK. Based on what I've been reading in the Headphones section of the forum, the Focal Clear sound like a good contender. Others have recommended Audeze LCD-2 and 2C. Looking forward to headphone recommendations, if you've got 'em. Back to listening and reading the manual...
