Hello Bear123 and thank you for your kind reply! Speakers are connected to the nad and i get no hiss. However, i noticed while playing some bass heavy tracks at high volumes (~ -10db in stereo mode, no sub, speakers set to large) it clips on some bass tones. I think its clipping and i do not believe the buchardts are to blame, its not "that" loud really. It sounds like an "oomph", like the woofer is hitting a wall. Or maybe thats the maximum for the speakers? That would be really disappointing
.
For movies, im ok with the receiver and after a lot of tweaking with dirac it sounds reasonably well for my not so ideal living room so as far as movies go, im ok with it. Im also using 2 opposite subwoofers and i managed to get as even as possible bass response in my room using dirac and test tones.
Everything works as expected with the nad but i wanted to also see how the buchardts would perform in stereo only with a better amp+dac and run them without subwoofers. Actually, my room helps the buchardts to easily hit 30hz and with more power i figured i could have a better music experience as well as removing the subs.
