Doug Schroeder Method, Double ic

I ran a pair from my preamp to a Sunfire Class D amp. No issues at all. I didn't notice much difference though. I just did a pair from HDD/streamer and that produced better results. 

I used the metal F or Y style hard connectors. I wrapped them in electrical tape since they are in close contact at the back of the preamp. Does it matter if they make contact? Did I waste my time wrapping them with electrical tape? 

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.
