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....

Sorry I haven’t read all the posts but does this method require identical pairs of ICs between the two components or there’s still some improvements using different ICs? I have an extra pair of good ICs and some splitters that I can try but just wanted to ask. Thanks.

kalali, you should read up on the Schroeder Method to find out, among other things, that it is a "do at your own risk" technique. It is in the experimental stage in terms of finding out the parameters of its use.

It is recommended to use four identical ICs, but I believe that member jayctoy has tried combining ICs of different makes. You may wish to talk to him here as well. As far as improvements go, I presume that even when using mismatched pairs of ICs the Schroeder Method would provide potentially superior results over a single IC.

Also note that it does not take expensive ICs for it to work.

Mind if I ask what components in your system you will be trying it on? No class D amplification, right? "

Doug - The above is is an excerpt from your 10/24 post to stringreen.

I have a Class D amp.  What are the issues when using a "double?"

maxima95, well, it's good that you ask rather than ignore the advice. My understanding is that the double IC can potentially cause instability in the operation of a class D amp, causing it to oscillate and potentially cause damage to it. That is why at this time it is not recommended for class D. 

Sorry that it is not recommended that you join the party at this time. :( 
If someone is hellbent on trying it, I adjure they must speak with their manufacturer first. This is a do at your own risk activity, and from the designers and theorists who are advising me the risk falls squarely more so with class D and with less robust specialty amps. I do not have all the answers to this and only with time and experimentation will much more be known about the parameters of the Schroeder Method.  

The caution in regard to class D amps in no way makes the Schroeder Method ineffectual; it's impressive with class A/B amps I have used to date, and with the Benchmark Audio Class AAA amps. The Benchmark DAC3 DX and AHB2 amps in Mono are superlative with Schroeder Method, among the most exquisite sounds I have had in my room to date.
