No "tweaks" required ;-)
Fairly broad: Bach, Coltrane, Hendrix , Cash, --and on and on...
Mechanical clocks and watches; air-cooled engines; old telescopes; vintage bicycles and motorcycles; anything useful of quality and manifesting a thoughtful design ethos
As an audio designer, I strive for sophistication in refinement, rather than mere complexity.
The quest for absolute highest quality sound reproduction is my central imperative.
Modularity, simplicity, serviceability, durability: principles that correlate with timeless, obsolescence-proof devices of enduring value and utility.
