I have the Scala Utopia, which, offers somewhat similar challenges as the Stella Utopia (albeit on a smaller scale). It sounds harsh and revealing with some equipment.
After a lot of experimentation, I’ve settled onto this for musicality:
1. A basic $5k R2R DAC (Holo May)
2. (Very important) a musical, euphonic preamp (I’ve had McIntosh tube preamps before but nothing beats my current Hegel P30. Feels like I am using tubes but with none of that noise / distortion at higher volumes)
3. (Very important) ‘warm cables’. I moved from silver-based power cables to copper based ones (AQ Hurricane)
4. Hegel H30 amp to match my preamp
Very musical, with ‘meat on the bones’ type presentation.
