Nasaman, Jeff Rowland uses switching power supplies (including Capri) for low noise. He also uses switching power supply in his latest designs Model 625 and 725 that are class AB amps. He explains technical reasons here:

Transformer doesn't have to be large to carry a lot of power - it all depends on frequency. His power supplies operate at 1MHz (easy to filter out), zero voltage/zero current switching, have power factor correction that presents resistive load, and are line/load regulated. In comparison linear power supply is in reality a primitive switcher that operates at 120Hz and produces high current spikes (since it is switching at max voltage). It is also unregulated in power amps (providing power to output devices) because of poor efficiency.
You can easily find really bad switchers (often in computers) but you can also find really bad linear supplies. Don't discard new technology just because is called "Switching Power Supply". Linear in spite of its name is also a switcher.
Have you seen this review:http://www.audioenz.co.nz/2007/rowland_capri-102.shtml
It suggests that Capri is better than 102. I use model 102 in combination with power factor correcting conditioner. Second generation class D amps from Rowland or Bel Canto have power factor correction built in.
