I've run my CW IV with a Naim Uniti Nova, which is a really nice match for the CW IV. SS & Tubes each have their own unique strengths, which is better would be a matter of personal taste.
For me, bass performance was better with the Naim but not by enough of a margin to keep me away from tubes. My preferred amp with the CW IVs is an Audio Note Cobra. It's a Class A PP EL34 design that puts out 28 watts, mid-range is fantastic (superior to the Naim) and it's dead quiet--even at idle.
