I have a deep respect for the NwAVGuy work on the O2 amplifier and like so many other enthusiasts around the audio circle I wonder what happened to him, so I really wish he is well and happy.
There are some theories behind his disappearance. NwAVGuy’s death or the death of someone near him, got a job on a big ass company and must remain quiet, JFK style assassination paid by some audiofail companies (this one is a joke, OK) or maybe he just got tired of all the circus behind audiophile gear and stopped working for community for free. Removing the death by assassination, I think all of those options are valid
but I’ll go for the real death of NwAVGuy. Nobody knew his age for sure so he might have kicked the bucket without telling his family about his endeavors. If he is alive I’ll be truly happy, but after so many calls from the community and so many time gone by, something really went sideways in his life for sure.
Dead or alive his legacy will not be forgotten by the community.
