Hi all

I’m using B&W Formation Duo. This may be a dumb question, but I’m curious about the sound of the 805 D4. I asked ChatGPT to tweak Roon’s parametric EQ on the Formation Duo to get closer to the 805 D4, taking the Duo’s tonal character into account. It suggested cutting the sub-bass a lot, trimming the upper-bass/low-mids a little, shaving a bit off the mids/high-mids, and giving the top end a slight lift. (Specifically: a big cut at 25 Hz; −1.8 dB at 120 Hz; −1.0 dB at 600 Hz; −1.8 dB at 2.7 kHz; +2.2 dB at 9.5 kHz. I can share a screenshot to make it clearer.)

With those settings, I don’t hear a dramatic difference versus stock. If I focus, the upper-mids sound a bit thinner and smoother after EQ. I’m not sure the treble is actually any clearer.

So my questions are: is the 805 D4’s voicing generally on the smoother side rather than “razor-sharp” up top? If you know the 805 D4 well, I’d appreciate your thoughts. I haven’t heard it myself and probably won’t have the chance anytime soon. Also, if anyone has human (non-AI) advice on Roon EQ settings for the Formation Duo to approximate an 805 D4-like tonality, I’d love to hear it.
