Christian, your system looks and must sound great!
Congratulations on your DIY speakers, I followed your earlier thread
I have the Burmester 911 on my shortlist, maybe as a pair of monos
I noticed you had an Aurender streamer before (which model?), how does the Burmester 151 stack up?
And seems you added the Esoteric LS, assume that must make quiet a difference
Enjoy!
