Still nothing new on this one, but the project is definitely not abandoned.
The idea of building two low noise, assymetrical (+14 -28V) high current power supplies is not overly pleasant.
Transformers and caps are expensive, suitable chokes are hard to find (and expensive) and active regulation means more heat to get rid of.
Would SMPS be the answer? Ebay is flooding with cheap chinese SMPS units available in different power and voltage ratings.
The output voltage is usually adjustable +-10% and best of all, I already have a few 12V 100W units.
Buying two 24V 200W supplies wouldn´t break the bank, but my gut feeling thells me that feeding this brutal/delicate class A amp with switching power supplies would be like throwing pearls for the swines...

Size (they could easily be be hidden between the heatsinks)
Simplicity (just plug and play)

...would I ever be able to forgive myself for taking the easiest way...? The balanced follower should be pretty much immune to PSU noise, but anyway!

Before anyone suggests it: Buying six 12V 100Ah SLA batteries is not an option...
