Doug Schroeder Method, Double ic

I just finished building a pair of Doug S. double balanced ICs using Connex/DH-Labs BL-Ag solid silver bulk cable, and compared that to a single run of the same cable.  It's not a fair comparison, as I also replaced standard Neutrik connectors with premium Bocchino XLRs with solderless terminations.  After a few hours break-in the improvement is spectacular-- detailed, smooth on top, organic mids and LF, and a deep wide soundstage.  The application is a 2M balanced run between an Esoteric K-01X and an Atmasphere MP-1 preamp.  I'll be curious for Ralph's findings as well. 

I made another 2M Schroeder balanced IC, this time using Oyaide Focus 1 XLRs(instead of Bocchino) with a double run of Connex/DH Labs BL-Ag, between AtmaSphere MP-1 preamp output and Merlin BBAM line-level equalizer into modified VSM-MX speakers.  This is a clear improvement relative to Neutrik XLRs using a single run of BL-Ag. In additional to the customary audiophile plaudits w/r resolution, warmth, bass extension, et al., there is correction to tone and timbre to die for.  Next experiment I need to minimize the variable of the XLR connectors and drill down on the double runs.
