"Just wondering, what DAC are you using?"
A vintage Sony DAS-703 ..... circa 1985! Yep,1985! It's temporary until I find a replacement for it. Though, I was hoping to bypass the streamer side of Bluesound and use its dac to confirm in fact the vintage DAC is causing my ear fatigue and not the Aurrender N200.
For what it's worth, the vintage dac sounded fine when used with the Bluesound Node. I could listen to the pair for hours without ear fatigue.
