Thank you for your kind words. I can add a bit more detail as it seems to be appreciated. In the photos below you can see the IEC inlets we have evaluated. The Oyaide PP-inlet with a Palladium/Platinum plating (successor to the better known Oyaide R-inlet). The Rhodium plated Furutech FI-09 NCF which has been "modified" to drop into an existing standard IEC cut out, I've also attached a quick MS paint drawing of what you need to cut away to make it fit. And last but not least, the Bocchino Giotto G2 (silver plated).
Interestingly there's a quite pronounced difference in sound signature between these. The Bocchino is big and bold "sounding", on the warm side of neutral, in the Extreme it takes that aspect a bit too far netting out into an over bloated bass section and a slightly too laid back presentation, you can balance that out by playing with different wiring and you can also get it with Platinum plating which most likely changes that (did not try), but it does not fit physically as there's a big chunk of Panzerholz in the way, furthermore the availability is questionable and you can sometimes run into IEC plug compatibility issues. It does most definitely win the coolness award and generally speaking (ignoring voicing compatibility aspects) it's the best of the bunch. Bocchino makes an even larger IEC inlet called the "Mariner" which is huge at about 2x3x4" which accepts OOO gauge wiring! All custom order with very significant lead times. The Furutech FI-09 is the most forward / direct sounding inlet, I would recommend darker wiring to go with it as it can be a bit shouty and highlight sibilance, imho on the cold side of neutral. Something to keep in mind is I have observed changes in character at up to 6 months of use. The Oyaide PP I consider to be the most neutral inlet, it does not have that ultimate weight the Bocchino possesses, but it has a really good and even clarity and detail from the upper to the lowest octaves without an excess in "coldness". It is compatible with all music styles and it also does work well with all IEC powerplugs, I have not run into any offensive combinations with it, our pick for the Extreme.
