You should know that Audiogon doesn’t really have to many folks that are into Diy,most are just plug and play types.
Anyhow I did build a couple of the first series camp amps with great results,I’ve also built the F5 and I had for a brief time a diy Sony sit amp that was push pull.
The new kits for the camp amps built as mono’s look very interesting especially for the sound you probably will get for the money.
After 40yrs of modding and building gear,I have no desire to try one,besides a Lyngdorf 2170 all in one allowed me to step off the amp,preamp,dac merrygorounds and stop chasing that dragon.
I do still tinker with speaker mods and computer digital front end though.
If the camp amps are your first project of this type,I couldn’t think of anything else easier and more satisfying.
Enjoy,
Kenny.
