The heart of the original proposition, I think, was to consider that money does not always equal best quality. Since I'm getting close to meeting my maker, I had the opportunity in the 50's and 60's to build amps out of various magazines--and found that a very good quality could be had for very cheap if you were a bit of an engineer. I went on to become a physicist, but never lost my love for designing and building my own amps. For a while in the 90's I tried to share DIY kits and ideas via forums, but found that the heyday of home engineers had passed. I had enough money back then to spend on the "high-end" stuff, nevertheless found it fairly easy to build something for a 1/10 or 1/100 of the price that was the equal or better in sound quality. Naturally, because of the ease in building them I gravitated toward tube designs.
It would be nice to see a real resurgence of DIY movement--it could certainly give the super expensive stuff a second option. Consider for a minute a "Macintosh" type power mono-block, built in China for less than $200-$300 and sold in America for $3000-$5000, or $15,000-$30,000 with the right marketing and name recognition. It may have some bells and whistles that are hard to add as a DIY, but then most of them are not needed if you are the user and can control your environment.
Well, I'm pretty much out of date with everything today, but it is fun to ramble. Thanks for listening.
