Doug Schroeder Method, Double ic

For anyone interested in the HAVE, Inc. products, please understand that they are a custom order house. You order it; you're stuck with it. (No refund-oriented, audition/trial period permitted.) Order from other folks if that bothers you. I would recommend Teo Audio for you in that case.

IMO, assembling a set of paralleled Teo Audio GCII's with splitters yielded a tremendous boost in my overall SQ over single run GCII's. I used the solid Monster products from a China company on Ebay. Perhaps a better splitter would further improve the resultant SQ.

So my HAVE, Inc. contacts sent the correct  2-ft run of Dual Canare StarQuad 110-ohm IC assembly terminated with AES/EBU (XLR) connectors. I compared it against the 2-ft run Dual Canare StarQuad 110-ohm assembly terminated with Canare RCA connectors that HAVE, Inc. sent to me previously. Both digital cables includes two paralleled Canare DA202 IC’s spliced together in the assembly (that is, a Shroeder Method paralleled IC assembly). So both digital cables include the identical Canare StarQuad IC conductor "DNA.” 

Both assemblies sounded very similar, if not identical, in terms of SQ. See my earlier post. 

Celander , my friend told me you can only use 75 ohm on rca  not 110ohm, is there a risk using 110 ohm rca? 

Digital coax connections use 75-ohm cable; digital AES/EBU connections use 110-ohm cable.

In principle, the both of these paralleled assemblies should have lower than optimal characteristic impedance. (To answer your specific question, the dual assemblies should have one-half the characteristic impedance of their single run counterparts.)

In practice, however, both provided better
SQ than a digital cable having the “true” characteristic impedance. I don’t pretend to understand the underlying theory for this result.
