I've owned the CW IV, for solid state the Naim Uniti Nova was an excellent match. The Uniti Nova provides a ton of value as an integrated amp, DAC, and streamer.If budget is an issue you'll save on components and cabling.
For tubes, I really liked the Audio Note Cobra and Triode Lab 2A3. The AN Cobra also had a capable built in DAC.
Solid state had the advantage for tight bass, tubes win in the midrange. Voices with the 2A3 were scary real.
