Lowering the noise floor


I am coming to the conclusion that success in home audio reproduction is largely about lowering the noise floor. There are so many different types of “noise”, from so many different sources, that we only really “hear” by their absence.

Those components, cables, accessories and tweaks that SUCCEED at lowering the noise floor, can, and do, dramatically increase sound quality. Sometimes the type of “noise” dealt with is controversial, or not (yet) widely recognized as being a problem. Sometimes the explanation of how a product works is dubious. Sometimes the way it is marketed reeks of “snake oil”. Sometimes the reviews singing its praises go over the top. While these things will certainly put off some prospective purchasers, they do not negate the audible results that are there for anyone open to hearing them.

Power supply indeed. But also power cords and cables. I think of a power cord as an extension of the power supply. As for the cables, especially interconnect cables, it is quite obvious too. XLR cables have no inherent advantage with short lengths.
I don't care if balanced cables with XLR connections are actually superior or not.  I'm going to keep using them because they sound good in my system, provide very secure connections and, truth be told, are infinitely cooler than RCA cables and connectors.

Just my take,
