Whatever Volti that fits your budget should be a good starting point. It’s been a long time since I heard Cary so I don’t know how it sounds, but, you are looking in the right power range. You could go even lower in power, but don’t stint on quality. If you can stretch to get the Synthesis Audio A40 amp, you will have a terrific s tube integrated amp that has a first-rate built in DAC. It runs KT66 tubes that, to me, generally sound better than KT88, 6550, KT120, and EL34 tubes.
I like the 40.2 Harbeth speaker for its rich sound and large scale presentation. It is not as dynamic sounding as I like, particularly at lower volume levels. Volti speakers sound more alive.
Good luck on your search.
