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....

No problem Doug! I figured the Crown XLS1502 was a good class D experiment. As in it was only 300 bucks so if things went wrong no big deal.

The XLI800 has a toroidal in it so wasn't overly concerned. I just like the idea that one could put together a low cost system even incorporating these Crown amps and spend extra bucks on the DSM cables and really elevate it to another level. Of course it does the same with higher end equipment also.

I certainly understand why you use the splitters. I will reach out to Bill and see what a pair of XLR DSM's cost.

Yes I have.  Double runs of 12 gauge Duelund Polycast wire on each of the three runs - Live, Neutral and Ground.  Very nice results. 
'Some SM IC compatibility info to share:

I've tested a pair of SM interconnects without issue with:

  • Class D integrated amp - Nuprime IDA-8
  • R2R dac with a vintage chip (AD1862) - Mojo Mystique V3
Before trying with the dac, I consulted the owner of Mojo if the double IC's would be an issue.  He said no.  Confirmed.  The above 2 components are in two different systems.

Anyways, I only have about 35 hours on the Acoustic BBQ IC's from @grannyring .  I'll report more after I get to 100 hours.  But so far, I am liking what I am hearing.  Previous cables are Signal Cable Silver Resolutions.



Some lovely additional input from veroguy; thank you! Your post strikes me as indicating you are a no-nonsense sort of fellow. This is also good input to share about class D use with another brand. 

One thing I noticed is that you seem to prefer the all copper Schroeder Method Acoustic BBQ IC to the standard silver/copper Signal Cable IC. That's not surprising to me. I happen to be using a silver/copper mix in my "internal" speaker wiring for the PureAudioProject Trio15 Horn 1, and I like the result. Ironically, this thin stranded wiring is from Radio Shack! I had a spool of it sitting for about, what, 6-7 years since they went defunct and decided to try it on the PAP. Works well, I suspect because of the silver/copper mix. But, I really do need to try a heavy gauge copper cable, maybe 10 AWG to see if that does better. I suspect it would. 

The good news regarding class D use is helpful for me, because I was hoping to do comparison between an active X-over rig with six channels of amplification versus a passive X-over setup with two channels (stereo or monos) with tri-wiring. I would like to use all Schroeder Method ICs in that comparison. This would involve the Legacy Audio Whisper DSW Clarity Edition custom speakers that can be switched between both modes. I did the review a while back for Dagogo.com (BTW, one of my conclusions was that I could make either passive or active speaker setup superior depending upon the complexion of the entire system. But, in an apples to apples comparison, i.e. amps, active x-over was superior). 

I already have gotten familiarity with the two channel and tri-wiring the Whisper speakers, but was holding back on Schroeder Method with the active x-over and 6 channel of class D setup because of concerns voiced to me about it from industry members. Now, it seems that the momentum is building to conclude that Schroeder Method is benign to Class D. I am still not willing to go promote it as universally benign (erring on the side of caution), but I am encouraged by the feedback!
