Despite the well-meaning intentions of those who wish to help prevent us from spending money unwisely, I recently purchased the Reiki Audio switch and upgraded power supply through Liquid Hifi. (See: reikiaudio.com) It seemed more thoughtfully designed and built than the others I considered, other than the one from Taiko.
Newly installed, it brought a sizable and unmistakable improvement over my previous switch - the English Electric.
I don’t think expensive network switches are for everyone. They range from an expensive accessory to very expensive accessory. And I can imagine some home networks will benefit more than others, some less, based on the many variables present. Nevertheless, for me, it was an entirely reasonable and worthwhile investment.
YMMV.
