OP,
I had a look at your system. Looks like you have about $10K in your preamp and amp or an average of $5K / base component. So, you should be looking at a Streamer and a DAC for that price range. Don’t worry about interconnects, those come after you have well matched components… maybe a year or two.
So, for a streamer, I recommend an Aurender N150… well, better yet an Aurender N200. Then a DAC for around $5K… hmm, I am having a problem in that price category. I like the Audio Research REF 9 and Berkeley Alpha. Too expensive. The Schiit Yggdrasil… to budget. I’ll have to do some research.
