Congratulations! Wow those are some speakers.
I would not blame you on swapping the DAC. It is often described as ruthlessly revealing. Something more natural sounding might enhance the musicality of the presentation.
My new speakers
After owning Monitor Audio PL500 II speakers for 10 years, I’ve purchased my last speakers, YG Acoustics Sonja 3.3s. They are definitely different than my Monitor Audio PL500 II speakers. In my opinion, Monitor Audio PL500 II speakers offer a great value and do many things well. BUT, the Sonja 3.3s are clearer, tonality is improved, more dynamic and instruments/singers are more palpable. I’m not suggesting a night and day difference, but easily discernible differences. Unfortunately, Incremental improvements are very expensive in this hobby. I would say that I’m done, but I’m sure I’m going to change my Chord Dave DAC.
