You are correct - the higher the impedance of the plate load, the better the sound. I've done the experiment in a preamp, with four different values of plate choke inductance plus a current source.
As noted below, electronic current sources for power amplifiers have some practical issues (of which I feel the safety risks of high voltages are the worst). So I elected to increase the plate choke inductance instead. It is nearly doubled from the previous design. That pushes the parafeed cap/plate choke resonance down to 7.5Hz.
