Hello Shahriar,
Niced that you want to built my amp! I'm sure you will be happy with the sound.
I am also using active xovers, at the moment a heavily modified Behringer DCX2496, see my website for details if you are interested.
You can lower the power supply voltage for lower power, but maybe 28V is a bit too low, I will check and let you know. I can give you the changed component values for a lower supply.
I will also see if I can dig up any measurements I have. I must say after designing amps for 25 years I know what to measure and what to listen for, and that numbers don't tell the whole story, so I don't tend to measure all of the things you mentioned.
Do you really need a balanced input stage? I can give you an example, but if you don't absolutely need it it is better to avoid an extra stage.
