I think both rectifiers you mentioned are good. For filtering caps i tried RIFA but not good. Now I am using hypex stock power supply with BHC slit foil. I also tried Sikorel and is really good. I already have 2 mono UCD400AD with linear power supply. I am now building a HT system so I want to use SPS80.
In fact, I have 2 x 1500W transformers already for (UCD400) but it is too big for me. If you want I can also sell it to you!
BTW, I think it is safer to use bleeder resistors.
