Another stunning result for the Schroeder Method. This time using XLR connections to a class A/B amplifier not previously tested, fed by an integrated DAC. The results are overwhelmingly positive. Though I have tried the amplifiers in all possible conventional permutations with this system, keeping the interconnects the same as a baseline, I have not gotten this caliber of sound quality using single ICs. Simply put, in every instance to date the sound quality when using the Schroeder Method is par excellence.
