Thanks for all the great feedback here. I have a lot to research based on this.
I already have Roon Core running on my network so nothing to change there.
As a couple of you mentioned I might be moving backwards... I've thought about that too. so many options, like do I look at just upgrading my Lumin u1, or possibly taking the next step up in R2R/discete DAC's.
I don't need to change anything, so why I'm looking mostly used, so I can try a ton of stuff and resell if it doesn't work. The Meitner and t+a do intrigue me though
