I am very pleased with the continued success of Schroeder Method (And why wouldn't I be pleased, if I say so myself!) in systems that I am assembling. One terrific outcome is the Small Green Computer sonicTransporter i7 4T AP with the SONORE Signature Rendu SE; Exogal Comet DAC - the Schroeder Method cables employed in this setup are here, between this integrated DAC (NOTE: for this setup you MUST have an integrated DAC with preamp/volume control function!) and they are Clarity Cable Organic XLR using the Audio Sensibility XLR Y-Cables; Benchmark AHB2 Amplifiers in Mono mode; TEO Audio Reference Liquid Speaker Cable doubled up (used precisely parallel) with the LIquid Standard Speaker Cable to the PureAudioProject Trio15 Horn 1 Speakers.
Very, Very pleased with the sonicTransporter and Signature Rendu SE combo as source.
The Comet and AHB2 is a fabulous combo with Schroeder Method and Clarity Cable Organic IC. These products are capable of so much more than even the manufacturers know. If they have never done double IC they likely do not know the capacity of their wares.
This is a stunningly pristine system that has breathtaking sound field depth and nuance. I do not often recommend a complete system, but this is one that an enthusiast could move into a horn hybrid speaker and be assured of a remarkable outcome. Note: I also use the Legacy Audio XTREME XD Subs with this setup, as the open baffle PAP Horn 1 can use a bit of extra LF. I have gotten used to very clean LF at about 16Hz +/-3 dB in reference rigs, so 30 doesn't cut it. YMMV
All these items are reviewed by me at dagogo.com, and none of them performed close to the level they are now with Schroeder Method. In comparison systems set up with single IC are significantly compromised - as are all components with single IC typically.
As long as the user understands the do at your own risk nature of it, a person who successfully utilizes Schroeder Method is all but assured the sense of hearing an entirely different/upgraded system.
