I could write a small book on my audio adventures but here is a small introduction.
Built amplifiers during the late 60`s and beyond, early 70's worked with Grateful Dead building speakers for what is now called The Wall Of Sound, mid 70's hooked up with Marco Karpodines designing building and selling the Delphi Imager speaker later to be called simply The Imager speaker, during this time Bendini gave us amps that we modified to our own specs that had our own face plates, we brought in some of the first Goldmund TT's some with Imager logo, helped with the listening of the first Infinity speaker along with the development of the Infinity amp, friends from the Skunk Works developed the Lazarus amps had a small part in that, ect. ect.
My real job was working for the Federal Govt. and in the early 90's i had to bail from Marco Karpodines and the audio industry because my job required more of my time, i could no longer do both so i stuck with what offered me a retirement and medical benefits.
After my retirement 17 yrs. ago i started going to Audio shows again, i started to meet people that remembered me and before i knew it i was evaluating equipment for manufactures and several importers, not for money i did this because i enjoyed it, i did this for some European company's that did not even have a market base here in the US along with many well know manufactures. I did this up until about 7 years ago as it got to the point where it started to feel like a job and most of what was sent to me during the latter period were DAC's and streamers.
During the end of my evaluation period i was introduced to class D most being from European manufactures, i heard potential but too many boxes were left unchecked, to be honest i cannot count how many variants of class D i evaluated. I continued on my own to investigate the latest of class D, buying with my own money or having in home trials offered by some manufactures, the in home trial was how i was introduced to the AGD Audions and i bought them because they fulfilled the promise. They are some of the best sounding amps i have heard period.
