A blog about the journey of a DIY Audio enthusiast who doesn't care too much of the 'esoteric' ultra-priced commercial hifi equipment. I may be wrong, some or most of the time, but hey, it's my journey and I welcome you to share with me on that journey. Currently interested in headphones, open baffle speakers, full range drivers, tube amps and Pass Lab Class A designs.
