Over narrower band width, to color, "spice," "flavor" more? 
It would depend how the Fundamentals Channel is used. The YO186 has phenomenal lower MF, not the “amount” but quality. The attention and personalization with which YO186 portrays the regions of tonal unfocusness are just stunning. So it might be fantastic candidate for Fundamentals Channel and I have written about it. However, it might be a fantastic candidate ONLY if a playback uses a fully developed Fundamentals Channel and the channel is use at 0dB within one or two octaves.  For instance if the Fundamentals Channel is used as I do in Macondo then I think that it does not make scene. In Macondo Fundamentals Channel is too narrow and runs at ~ minus 6dB, so it provides juts filing of weight for MF. I did tried different amps in there and I feel that it was not worthy as it more about the lower MF “fog” then the actual sound. I still use in there a single stage-amp. If my upperbass would roll off sooner with low-pass or if my MF would roll off sooner with high-pass then I would consider DHT on fundamentals. I intentionally do not want to roll off upperbass sooner as I need more reductively from upperbass. Do not forget that in Macondo the upperbass servers also as the vertical imaging anchor.

Where I would LOVE to try the YO186 it would be the upperbass channel – this would be VERY interesting. I would load it to 12K-14K to do so, but I afraid that it would not have power to drive upperbass in A1
