Doug Schroeder Method, Double ic

aolmrd1241, yes it is a most interesting thread, especially when the result is heard! The Schroeder Method became VERY interesting when it worked superbly well the first time I tried it! It continues to gather momentum among those who are trying it. (Please note all the caveats and warnings with certain systems). You would do well to refer to my original article at Dagogo.com; I believe it is linked here in this thread. 

In regards to a preamp having no room, I have yet to find a component where I could not affix the Audioquest splitters for the purposes of the Schroeder Method. I may have to orient them differently, i.e. with the cables approaching the post from the side or top, but I can get it done. 
I could care less if cables are protruding above the component, as the sonic result is what matters. And when this result is heard one quickly forgets about the issue of position of cables. 

Different preamps (and sources) have varying degrees of distance that separates L/R channel connections. The Monster-styled, solid Y-splitters provide the most challenging connections, whereas the AQ-styled, extended-tailed Y-splitters providing a bit more space. The plurality of paralleled IC pairs can be dressed by applying a loose twist to each pairing (or using Velcro cable ties as needed).

celander, yes, there are differences in spacing between L/R outputs on preamps and amps, but I have yet to use one that cannot accommodate the Audioquest RCA Splitters. The splitters are no wider than the standard RCA cable. 

If a person has challenges with splitters and spacing, then try a "y" cable instead, which should alleviate the problem and accomplish a similar, though not identical outcome. 

..just checking......the Y connection for balanced cables in this application needs to be female XLR to double Male, and then double Female to single Male....is that right?

Yes, that is correct. You will find that precious few XLR makers have the second version, the double female to single male. I found one online that was cheap, but sounds poor, and another that was marginally better  for pro sound applications. Neither are acceptable for my purposes. I spent maybe $75 on them total as a cost of testing. Well worth it to establish that the quality of the Y cables are crucial to achieving the best outcome (when Schroeder Method is used with splitters/Y cables). 

I was directed to Audio Sensibility and am now testing XLR splitters/rejoiners as indicated above made by that company; so far, superb results.  Audio Blast article pertaining to Audio Sensibility specialized products for Schroeder Method underway. 

 I currently am using the XLR cables under review in Schroeder Method configuration between the Benchmark DAC3 DX and a pair of Benchmark AHB2 Amplifiers in Mono Mode. Rocket ride, baby!
