I don't know what CDP you have and its output voltage and impedance. 3dB of attenuation would halve the output. 10dB is a lot and could well explain your results. If you have done this because you don't like that the volume control only gets turned up a little attenuate the output of the pre to power amp connection instead.

What pre is it? What CDP and what power amp? Are you actually overdriving the input of the preamp to distortion\clipping that you connect the CDP to? Which input is that? Modern CDP's and sources have a much heftier and most often SS low impedance output of two volts or more. Vintage tube sources were usually lower output and definitely a lot higher output impedance.

Again since it is so easy try the Rothwells between pre out and power amp in. Good luck.
