There were an army of Do-It-Yourselfer's(DIY'ers) who committed themselves to figuring out the design behind 47 Labs famed amp a few years ago.
Checkout Since there were only 9-15 parts in the whole sheebang, it didn't take long. A decent working model really shouldn't cost more that GainClone.com, it is solely dedicated to DIY Gainclone designs. Also DiyAudio.com's ChipAmp forum.
Since there were only 9-15 parts in the whole sheebang, it doesn't cost a lot ot make one, although it did take a lot of experimentation over a a couple of years to get the best out of it. The evolution of the GainClone was an impressive group effort to watch. Some pretty talented people were actively involved along with a slew of beginners. Literally hundreds of permutations were tried. Which really stands as a testament to the effort 47 Labs put in because it was all done by a single person. (though, his prices - sheesh!)
Anyway, some of the DIY crowd went on to make actual commercial products. ChipAmp.com sells complete Gainclone kits of tried and true high-performance designs. Everything you need for ~$80.00, excluding chasis and knobs. Also, Peter Daniel, one of the mainstays and leaders of the DIY movement went on to offer the Audiosector Patek line of amps as reviewed favorably by 6Moons.com webzine. They also sell kits.
