Doug Schroeder Method, Double ic

@ozzy I’ll defer to @douglas_schroeder to address that question. 

A couple thoughts interjected... 
No one as of yet knows why the Schroeder Method works, least of all me! I claim no pedigree, only curiosity leading to the discovery and implementation. Speculation would be expected until such time as a cable manufacturer would chase down the explanation, if measurable.

Yes, I have done it with both RCA and XLR with analogue signals, as well as AES/EBU (XLR) in one setup from transport to DAC. I also have successfully done one RCA  setup of Schroeder Method between preamp and amp. NOTE: ALL PREVIOUS WARNINGS AND CAUTIONS APPLY; this is a "do at your own risk activity". It should be avoided with certain amps, as has been forewarned, as well as some DACs that output from the chip (ie. No opamps) etc. Again, check with your equipment mfg. Or designer as regards safety.

Imho, the Schroeder Method is a system cost saver, not a money waster. Double the price of the materials and 4 splitters is a gift given the result in every instance I have done. Others who have tried thus far seem to agree. I certainly don't mind a perceptual $10K component upgrade for the cost of one more pair of interconnects, or doubled pair. :)

Finally, funny how everyone, even designers find their pet reasons for cable performance. My most consistent benefit in cables across prices and brands has been, aside from conductor material, heavier gauge. Consequently, the idea for the Schroeder Method grew out of many years of pushing heavy gauge cabling in rigs and getting what is to my ears better sound. Ymmv

Ozzy, please pay heed to the recommendations in my article and notes. While it may work, I do not recommend mixing the cables. I'm not saying it won't  work, but i am not publically endorsing it. I would think that might be a concern best avoided.

If anyone is familiar with Morrow Audio cables, he adds more runs of his special wire to achieve higher resolution, etc., as the price goes up. I have a pair of MA3 with 12 runs of wire and a pair of MA5 with 36 runs of wire. The MA5s are quite a bit better in every category of music and sound. Is this a similar thing to what is being discussed here ? Thx, Enjoy ! MrD.

@mrdecibel I think the MA assemblies with the SSI tech wires are “conventional” in nature (think Canare Starquad but only at a much higher level with respect to one type of conductor).
