Because your room geometry (large, L-shaped, sloped ceiling) introduces modal and reflection asymmetries, digital correction can bring substantial benefit, but the key is choosing a DAC or front end that balances musicality and room-adaptive precision without trading away tone.
To start with I'd recommend testing DACs that combine musicality with correction capability. Keep D’Agostino, WB, REL, Aurender.
Your system already performs at a high-end level, so the next improvement lies in tonal balance and room integration rather than component resolution. The L-shaped, sloped-ceiling space emphasises brightness and bass unevenness, which makes the Chord DAVE’s analytical sound more apparent. To achieve a fuller, more natural presentation, the best path would be a DAC or front end that adds harmonic richness and allows controlled low-frequency correction.
The Weiss DAC502 Mk2 is a very balanced option, offering natural tone, fine resolution, and built-in DSP for subtle room shaping. The Trinnov Amethyst is ideal if you want full 3D room analysis and correction.
An alternative approach (personally my preferred option) would be to do DSP Room Correction analysis with REW and then upload the response into Roon. This method lets you correct the room digitally at the source while keeping your DAC and amplification performing at their full natural character. That way you can address any room issues via Roon MUSE, without the need for a DAC with DSP capabilities, but rather focus on true high-end DACs perhaps with R2R, True1Bit, PCM+DSD etc.
Hope this helps
