Very good intention! so everyone will be able to start experiments by themselves but even beginners could build the Paradise by guidance of the chief engineer!
Hurrayh!

It could start with this transformer. Simply rectified it has too much voltage. We can drop the voltage in resistors or we can use coils. One transformer is enough for both channels but 2 can be used for double mono.Transformateur R-CORE à fixation sur châssis 30VA - 2 x 24V - Transformateurs R-CORE pour châssis

This rectifier diode is hopelessly over dimensioned but hyperfast and soft recovery.
Other like Fairchild make similar products.http://www.hifituning24.de//downloads/hfa08tb60.pdf

Damn, the 4 poles are expensive, the two poles are ok but there are more affordable alternatives.http://www.mundorf.com/deutsch%201.1/kondensatoren2.htm

These might be very nice on a Power Amp and surely work great on the phono as well.

Why not. My vote goes for CLC with Hammond chokes or, maybe even more economic, with gyrators as choke replacement (good reading - sry, german only: Spannungsregelung mit elektronischer Brummsiebung (komplementär-darlington, LM350, MJE2955, MJE3055)).

I would vote for a passive solution with coils.

Good alternative ? Seems to me they have quite same specs.
