Not really. This design has been carefully optimized to give very low current spikes through the diodes and transformer secondary. Most modern linear designs will just use a large cap after the diode bridge. For a 1A load that will produce somewhere between 12 to 20A current spikes depending on what capacitors you used. Even if you go with a standard PI filter out of the textbook and design it the standard way you will still get current spikes in the 3-4A range, alot better than 12-20A, but this design gives you current spikes in the 1.5A range.
I never stated that this was a new unique never seen before power supply design, just that it was a carefully optimized design targeting parameters I have found to be important for audio purposes.
