Wasting your time and money, when a very tiny handful of audiophiles buy a tiny handful of audio gear through a tiny handful of audio stores, to me, you don't exist.The problem is audiophiles are such narcissistic arrogant a-holes they don't realize what a tiny insignificant universe they live...
Hi-end audio died a long time ago, because it does just the opposite of what your supposed to do to create a successful industry.
Hi-end is weird impractical products that few want at a price no sane person would ever pay, sell through a few stores that few can find, and fill it with snooty...
Another one of my just for fun microphone designs, the element is a 2" computer speaker with cone removed, the 6.3 volt transformer wired in reverse gives me 20db of gain.the sound is shall we say unique.
My most elaborate mic design, the element is a headphone speaker, with a passive EQ and athe amp from a computer speaker, the sound is pretty good, with only a slight ringing from the springs on loud transients.The whole thing runs off of 4 d cells.
