Tubes questions

Can anyone tell me is the art audio diavolo with the discontinued KR vv32 tubes can be use with the KT 300BXL tubes?. also any input about the sound of the VV32b tubes Vs other tubes like 300B or px25? thanks
Did you ever get an answer to this? Some of the professional reviews suggest that you can just pop in the 300BXL tubes. I have a used Diavolo on the way and it's coming with the 32bs but I was wondering about trying 300BXLs to compare.

And how do you like the Diavolo?
