Thanks for your thoughtful reply. My digital sounds very good to my ears so I need to keep the AN DAC. It brought my digital so much closer to the musical enjoyment of vinyl. That in the addition of a six pack of REL subwoofers. I actually had a friend bring a Phoenix clock over and I heard it in my system with my Zen 3. It made a material difference that I really liked. So my plan was to buy the clock. But then when I add the clock and the cable and another power cord, it's not that much different money to just sell the Zen 3 and buy an Evo aeon or for a couple thousand more get an innuos statement. Given the improvement I heard with the clock, I'm sure the other improvements would yield some benefit. And my digital is sounding so close in terms of musical enjoyment to the analog now, that I may be selling my analog rig for now and using the money to upgrade.
So it sounds like you're saying that there are some benefits that would be better realized with a dac that can handle higher sampling rates. Given the above that I've said, does anyone think the Evo or the NUS are necessarily better for 16/44? Or is that not really going to be a factor in my decision? I'm going to be buying used so I probably won't get a chance to audition.
Thanks
