Doug Schroeder Method, Double ic


I think this topic deserves its own thread , where use double ic through y adapters , from source to preamp, Can’t connect it from Preamp to Amp...For me the result is huge, I can’t go back to single ic....

Thank you very much, piouser and shout1cobra, for your input! 

Doubling speaker cables has always been a good way for me to elevate a system's sound. Not sure what happened with the double 16 Ga. you used. I usually try to get the AWG to about 10 for speakers, and that means doubling some substantial cables. I'm not surprised at all that you heard more from doubling speaker cables when using the Schroeder Method. It is much more revealing of such things than standard single IC, imo. 

We must have half a dozen class D amps now in use with Schroeder Method, which is great! I'm guessing some others have tried and not discussed publicly, too. 

Good job, shoup1cobra, to try an alternative location, as opposed to simply� concluding that there is no efficacy because you didn't hear it in the first trial. I encourage you to get Y cables, as budget hard connectors might be quite lossy for the signal. When I was using hard splitters with some components they were very close together, and I always put a piece of foam or leather between them. 


Has anyone successfully used SM cables with SET amp(s) and/or transformer/autoformer passive pre(s)? I know there was some concern about both, early on.
This week I had my first shot at using a set of same brand pre/class D amp. I am running a double Schroeder Method setup, two pairs of double ICs, one set from DAC to pre, and the other from pre to Class D amp. The results are as typical, wonderful! On this particular review set of components I am using RCA for the first pair, and XLR on the second pair. So much more is extracted from the components when Schroeder Method is used.

I am in awe of what is happening with these electronics. I have heard a lot of class D, but never had one impress this much. It's not a high dollar unit, which the masses will cheer. I need to investigate how this is happening more thoroughly. Class D in my use is proving VERY agreeable to Schroeder Method. YMMV and please do your own educating on this topic before trying this "do at your own risk" activity. :) 

Also, in my use passive preamp has been of no concern whatsoever. Passives have worked splendidly with the Method.
I use my SM ICs on The Truth no gain preamp with great results. My customers use SM ICs on SET amps with great results.  No issues at all with SM ICs based on my experiences with customers on all manner of gear. 


I have read most posts on this thread and can confirm that the Doug Schroeder Method works well with my class D amp: Nuprime ST-10 modified by Bob Smith. I also have double DS Method ICs between my DAC, Marantz NA11S1 and my pre-pro, Marantz AV8802. My source is a Melco N1A server.
The DS ICs are Mogami Gold custom made by Pro Audio LA Chris Dwyer, so no splitter or Y-cables. They replaced two sets of Mogami Gold single XLR ICs.
I have been using them for 2 days now and can attest that they do sound better than the single ICs. Is the difference of the magnitude of a component change?  Yes and no. Yes, it's that obvious.  You can definitely say that there is a difference for the better. No, because in my case, the characteristics of my system did not change: the soundstage is wider, the top end is smoother and instruments separation better. So it is sounding righter than before but not different in its fundamentals and it's a good thing because I liked the way it sounded before.
The cost for the two sets of XLR terminated double ICs (1 and 2 meters) was about $175.
