Doug Schroeder Method, Double ic

ketchup. I understood your Q.

The only way to evaluate the SM complete assemblies without splitters is to compare them against the same IC’s used with Y-splitters. I did that with the HAVE, Inc. Canare IC’s (separate IC’s with Y-splitters vs SM integrated dual Canare IC assemblies).

It goes without much consideration that reducing 12 discrete external connections involving 4 separate connectors to only 4 connections will be a benefit for SQ.

I am very pleased with the continued success of Schroeder Method (And why wouldn't I be pleased, if I say so myself!) in systems that I am assembling. One terrific outcome is the Small Green Computer sonicTransporter i7 4T AP with the SONORE Signature Rendu SE; Exogal Comet DAC - the Schroeder Method cables employed in this setup are here, between this integrated DAC (NOTE: for this setup you MUST have an integrated DAC with preamp/volume control function!) and they are Clarity Cable Organic XLR using the Audio Sensibility XLR Y-Cables; Benchmark AHB2 Amplifiers in Mono mode; TEO Audio Reference Liquid Speaker Cable doubled up (used precisely parallel) with the LIquid Standard Speaker Cable to the PureAudioProject Trio15 Horn 1 Speakers. 

Very, Very pleased with the sonicTransporter and Signature Rendu SE combo as source. 

The Comet and AHB2 is a fabulous combo with Schroeder Method and Clarity Cable Organic IC. These products are capable of so much more than even the manufacturers know. If they have never done double IC they likely do not know the capacity of their wares. 

This is a stunningly pristine system that has breathtaking sound field depth and nuance. I do not often recommend a complete system, but this is one that an enthusiast could move into a horn hybrid speaker and be assured of a remarkable outcome. Note: I also use the Legacy Audio XTREME XD Subs with this setup, as the open baffle PAP Horn 1 can use a bit of extra LF. I have gotten used to very clean LF at about 16Hz +/-3 dB in reference rigs, so 30 doesn't cut it. YMMV 

All these items are reviewed by me at dagogo.com, and none of them performed close to the level they are now with Schroeder Method. In comparison systems set up with single IC are significantly compromised - as are all components with single IC typically. 

As long as the user understands the do at your own risk nature of it, a person who successfully utilizes Schroeder Method is all but assured the sense of hearing an entirely different/upgraded system. 

Sorry if this was already covered in this thread, but instead of building ICs with double the conductors in parallel, can you get get the same effect by using the normal amount of conductors at twice the gauge?  Meaning, instead of parallel runs of 12 gauge wire, just use one run of 9 gauge wire.

ketchup, I would suspect a lot of the benefit is from heavier AWG. There is no point in denying that is a major contributor to the success of Schroeder Method. 

However, the use of a second distinct ground may also play into the change sonically. The method is so fresh that there are more questions unanswered than answered. 

While use of a splitter or Y-cable is obviously not advantageous in comparison to a manufactured double cable, the advantage is in potentially mixing ICs of different brand/models to obtain the "flavor" of sound one wishes. Some users have already started to mix and match, and it seems with excellent results. 

And, as in speaker cabling, within reason if someone makes a lower AWG speaker cable, that, too can be paired, and what will the result be then? It sounds insane, but that was the thought that crossed my mind why I paired two interconnects in the first place. Knowing what doubting speaker cables does for the sound, I wondered what would happen if two ICs were paired, obviously doubling the conductor material. That is the kind of exploration I love in audio.  :) 

Correct, larger gauge won’t get you what you are looking for. I tried a standard 12 gauge set vs the DS method with 16ga and the DS method with 16 gauge was certainly better in every way.
