     I've recently been in the habit of posting information about upcoming DIY projects rather than waiting until a project is built and evaluated, since it's a good way to spend a lazy afternoon pondering insights, materials, assembly, and as a conversation starter in Tweakers' Asylum, since that's what this forum is for. This moderate-cost level DIY cable project is for an auxiliary application that requires a pair of long-length (5 meter/16 foot) line-level RCA interconnect cables connected to a digital CATV/home theater headphone amplifier located next to my La-Z-Boy recliner. While it's not a critical listening application, I'm still very critical of how it sounds if unpleasant, so it deserves special attention in order to provide an enjoyable, coherent presentation with good resolution and dynamics, suitable for general television and home theater audio, especially for late night listening purposes. The Mogami W2549 cable is a shielded twisted pair featuring a served shield, 22 AWG stranded conductors with a solid PE dielectric, and a pair of PE fillers to maintain a consistent twist ratio along the length of the cable, as well as a level of cable resonance control. The Mogami W2549 offers substantially lower capacitance vs. their star quad design for a long-length, line-level RCA interconnect cable, and the relatively large 22 AWG conductors are also a good choice for a long-length, single-ended interconnect application at a modest price-point. It's a popular low-cost product that should be interesting to evaluate for my particular application. The EIZZ EZ-201 RCA connector is a sophisticated design at a moderate price, involving various base metals, platings, and a Teflon dielectric that provides excellent clarity and neutrality. It's a good example of an RCA connector that is not a low-mass design, but it still sounds high-performance in nature as a modest-cost level option for an inexpensive interconnect cable like the Mogami W2549, which is most often terminated with mundane pro audio connectors that tend to be weak links in the signal chain. The EIZZ EZ-201 features a silver plated solid tellurium copper center pin, with a palladium plated (some sellers say rhodium plated) phosphor bronze body, and a Teflon dielectric, based on a Cardas RCA connector design, but with a better base metal/plating scheme, IMO. At a cost of only $80 for a pair of 5 meter cables, this inexpensive DIY build should be as interesting as any other DIY cable project I've evaluated over the years.
