You do not want to take the saturation down before converting, that is compressing the gamut range of the image prior to conversion.

Edit>> Color Settings >> Settings: US Prepress Defaults (this will chaneg your other settings, especially good to have Adobe 1998 for RGB.

Then convert RGB to CMYK If you still need more saturation and detail.

Float a copy of the layer.
Change top layer blending mode to Soft Light
Change transparency to between 30%-60%
If image is slightly to dark do a curves correction and take the 50% midtone dot for all channels to about 42%.

The problem of going from RGB to CMYK you lose saturation, by your post are you experiencing the inverse????
