Oyaide R1 vs. Furutech GTX-D NCF(R) AC outlets

Posted by Duster on March 12, 2016 at 18:19:11:
I find the sonic benefits of each AC outlet are (in effect) system, component, and/or listener dependent issues. Since they sound quite different, it won't be difficult to decide which one is preferable for a particular application, IME.

I have an Oyaide R1 and a Furutech GTX-D NCF(R) installed right next to each other in a power line distributor, so I'm able to compare the two quite different sounding AC outlets in a comprehensive manner. They provide quite different sonic signatures, and in my opinion can actually complement each other when implemented as customized system tuning devices. To a degree, the main aspects of their differences have to do with soundstage height and essential differences in tonality which may or may not be what a listener seeks for a particular component, or a systemwide gestalt such as the particular AC outlet installed at the wall that feeds downstream power line distributors/conditioners.

I find the Furutech GTX-D NCF(R) provides a taller soundstage dimension, and a more linear and leaner tonality from top to bottom, while the Oyaide R1 provides denser sounding images and a stronger sounding bottom end, with a more subdued treble energy in comparison. Some folks might find the Furutech GTX-D NCF(R) to sound more anylitical, while the Oyaide R1 to sound more musical, but these are subjective generalities based on my own opinions. YMMV

In my case, the Furutech GTX-D NCF(R) feeds my solid state preamplifier and DIP (Digital Interface Processor) with both power cords terminated with Furutech FI-50(G) AC plugs, while my power amplifier power cord terminated with Wattgate Gold is plugged into the Oyaide R1 with the second socket feeding a downstream power line conditioner via a power cord terminated with Oyaide 004 Beryllium AC connectors. For use with my my solid state power amplifier, I find the Oyaide R1 to be preferable to the Furutech GTX-D NCF(R). The effect of the Oyaide R1 provides a more natural acoustic vs. the more analytical perspective of the Furutech GTX-D NCF(R) when implemented for my solid state power amplifier, placed within my particular audio system. YMMV

For a tube system, the Furutech GTX-D(R) or the newer GTX-D NCF(R) are likely better options than an Oyaide R1 which presents a more subdued treble characteristic that may make the Oyaide R1 better suited for solid state systems with a more energetic top end. However, even for a solid state system like mine, the Furutech GTX-D NCF(R) AC outlet, especially when mated with a gold plated Furutech FI-50(G) AC plug is a stellar AC outlet/AC plug combo, not unlike the original "killer app" Oyaide SWO-XXX AC outlet/Oyaide P-079 AC plug combo, IME.

The same differences of the Furutech GTX-D NCF(R) vs. the Oyaide R1 can be found via the Furutech FI-50(G) AC plug vs. the Oyaide P-004 Beryllium AC plug. In my case, I re-terminated an Acrolink 7N-P4030II power cord originally terminated with Oyaide 004 AC connectors with a set of Furutech FI-50(G) AC connectors as an experiment, and found that the FI-50(G) didn't provide good synergy to my ear. In the case of the Acrolink 7N-P4030II power cord, I much prefer the synergy provided by the Oyaide 004 AC connectors when placed on a source component.

I recommend that folks might consider what I did, and install both an Oyaide R1 and a Furutech GTX-D NCF(R) in a power line distributor/conditioner in order to hear what each can do within their particular audio systems.
