You have one of the best speaker on earth.
Among all the reasonablly priced solid state amps I have tried, McCormack DNA-2 was the best with Confidence 5. For higher price solid state, I have heard Pass X600 are wonderful match with C5. I had Pass X350 and it better Rowland 8TiHC.
The longest amp I had with the C5 was Sonic Frontiers Power 3, but I did clip them occasionally when I played loud. Tubes are magical with C5, really brings out the Esotar midrange dome, but there are not too many tube amps on earth that can push C5.
