I've done what I call pseudo-DIY. I've upgraded components and experimented with some changes and took on a pretty sophisticated project from someone else's schematics and instructions, but I've never really DIY'ed from a complete design perspective. Some of my projects included, from simple to harder:
- DIY interconnects
- DIY power cables
- DIY speaker cables
- teflon coupling cap upgrades in my preamp and phono preamp
- DIY racks using sand boxes as built in isolation devices for each shelf
- power conditioners using multiple methods
- complete rebuild of my speakers, including wiring, crossover components, & other voicing
- DIY turntable using a Corian plinth, Moerch DP6 arm and VPI platter and bearing and motor
- large scale DIY tweaks to an Art DI/O DAC
- larger scale DIY tweaks and upgrades, including an output stage rebuild, to a Zhaolu 2.5C DAC
- complete recapping of a 30 year old NAD 3155 integrated amp (sounds wonderful again)
- complete amp rebuild on a McCormack DNA .5 Deluxe (bringing it to near rev-A)
- Mark Kelly turntable motor controller (this one was a bear, but it works now and is truly amazing)
So I guess I'm a DIY kind of guy. Or maybe I'm just interested in seeing how things work and how I can make them better, or how a change modulates and interacts with the overall sound.
I still haven't taken on building a tube amp from a plan/kit, but never say never.
