I should first and foremost state that, I am in no way affiliated to any business or am in the business of selling any of the mods I've mentioned. Heck, I dont even get a reviewer price for these stuff. However, what I do share with you all is a similar interest in seeing just how much squeeze out of these small little devices.
Now, unlike hifi speaker sets up, the headfi portable ecosystem is pretty much dominated by a few brands. The unfortunate side effect, is that because these brands have a stranglehold on the upper tier products, we have seen an snoball escalation of prices. The CU is one such product, now we will probably see the same for the next 4XX series.
But, what does that leave us? While I may be able to afford the next player and upgrade, that doesnt mean that I part willingly with my money. I am most certainly not keen to part with the probable 6kUSD for the next flagship which is probably just around the corner. Hence, I, and few of my friends, have turned to these mods in an attempt to keep our players relevant in an ecosystem that sees rapidly inflating prices should you wish to stay at the forefront of the hobby. This leaves us with two options; full out mods like the Redwine, mezzo or Ryzhou Musashi mods (which arent cheap btw, coming in at 1.9kUSD depending on the currency exchange mods), or these psuedo science mods.
Now, I would most certainly encourage anyone who can afford those full on mods to go for it, if they can afford the charges. I hope to send my CU for the Musashi mod at the end of the year when I visit Japan again, but that leaves me with much time to play around with stuff, which led me to these sticker and contact enhancer mods. I of course, had my initial skepticism about these mods, but I have the time, its reversible, relatively more affordable that the full-on mods, and can do no harm, so I went in with an open mind, and of course found myself rather rewarded with the results. My friends and I work on a similar mindset; one of us will stumble on a new mod, test it out, and if a change is perceived, introduce it to the rest of the group and see if said results are replicated.
Which, is what led to me posting here. This is after all, a community of 380 owners, and as such a great platform to discuss and pool knowledge together, regardless of how implausible it sounds. It is rather a sad state of affairs that the moment something contrary to your personal beliefs surfaces, naysayers will quickly swarm over to stone the dissident voice into submission. I just wonder how many other possible mods have never reached the pages on these forums, because its users have been too put off to share their experiences. I was most certainly going to share another project that I am working on in its relevant page, but at this rate, I think I'll just keep my silence.
