You wrote, .."all you are doing is puting in frount of the sound!" I presume by this you mean that adding the Rs to the filter is going to degrade the sound. To the contrary there are good theoretical reasons NOT to have a huge capacitance following a rectifier stage. The very small R does absolutely nothing to harm transient response (based on my listening), does have a small added filtering effect, and does reduce the massive current demands made on the rectifier stage by having only a single huge C for a filter (since the rectifiers "see" mostly the first capacitor and are to a degree shielded from the downstream capacitance). Bass response clearly got better after I made these changes. Of course one must use good quality high power resistors, and I used Mills 5W or 12W ones.
