An update to my original post.
I purchased the Small Green Computer SonicTransporter i7 for Roon DSP (thanks david_ten!) to solve my Zenith MKII Roon DSP issues. And just recently, I purchased a tube preamp, a used Herron VTSP-3A (r02). It pairs well with my NAD M22 v2 poweramp and Tannoy DC8Ti speakers.
Adding the Herron made a huge difference to my system and I am very happy with it.
My MyTek Liberty DAC works well with my system - but, I want a better one. I'm considering the newly released Audio Mirror Tubadour III Statement tube DAC. It's gotten excellent reviews, and with their 30-day return policy I figure I have nothing to loose.
