Regards,

1) minimum Z will be 3.5 ohm, maximum Z approx 20 ohm? maybe? (same speaker)
2) up to 200 W
3) SE
4) probably not, but if you can tell me where to find a turnkey Class II (no earth connection) PSU for not too much money, I would use one

- What power output do you want? 225 & 450 *
- Do you plan to run differential or SE input? Differential or SE is OK **
- Will you build a higher voltage regulated supply for the front end? Yes


* I only need 150 and 300 max, but I have 60V supplies so...
** I'm using MiniDSP which has differential and SE outputs. Differential output impedance is 560 ohms so may have to use SE which is no problem in my application.

150-200wpc

- Do you plan to run differential or SE input?

differential, not interested at all if the diff input is scratched, can get plenty of lme49830-fet amps without it all over the web, its the main reason i would build it and all of my gear is balanced, its what sets the build apart, good layout and compact too and i know the pcb will be high quality, but if you dont do it i'll probably get my own boards done at golden phoenix of the bal option if you would be cool with that.

yes
