Doug Schroeder Method, Double ic

What do you think is being filtered that is improving the sound?  What other ways do you think you could achieve the same ends?

All: I’m adding to my last prior post here to provide more context to the Canare Starquad story and their wiring scheme. As one can see from their wiring diagram, their 2 hot conductors are sliced together in parallel.  Likewise, their 2 return conductors are spliced together in parallel. Note one common shield element, however.

@kingrex I don’t think anything is being “filtered.”

Some speculate that the improved sound qualities perceived during even casual listening sessions is attributed to the parallel configuration having nearly twice the bandwidth of their single-run counterparts, with the attendant reduction in internal reflections for electrical signals transmitted through the parallel configuration relative to their single-run counterparts.

I’m not aware of other ways of achieving this effect. If the “increased bandwidth” speculation is the correct attribution to the audible improvements in reproduced sound, then interconnect designers should devote their energies to designing cables having the greatest bandwidth possible. But even then, implementing the Schroeder Method to those cable designs should yield further improved sonic benefits over their best single-run counterparts.

@elizabeth A single cable assembly is certainly preferable to using 2 single-run cables with terminal Y-splitters at both ends. But using a set of Y-splitters (4 total for a stereo run with 4 IC’s) is inexpensive enough for one to tinker with the method in the short term.

Teo Audio makes a Double-Double version of their liquid metal GC-II Jr as a set of paralleled assemblies terminated with single RCA connectors at each end. (Alas, their A’gon listing expired earlier today, but I’m sure they’ll relist it.). Taras of Teo Audio (@taras22 here) shared listening impressions of that product compared against some of their pricier single-run cables. See one of the Teo Audio threads in the “Cables” forum for that post.
