About Me:

Disruptive innovator in digital audio using ARM Cortex M-series and cheapo multibit DACs.

Interests (Hobbies, favorite activities, etc.):

Music, philosophy, engineering, gadgets, teas, curries, gals.

What I do for a living:

Multibit DAC designs and classA and D amps. Rest of time teaching English one-to-one.

Headphone Amp Inventory

All designed by myself - a mixture of classA SE and FDAs via custom-wound transformers

Source Inventory

SD card players (QA550 and Taobao-sourced one using STM32F407) feeding homemade multibit DACs ( TDA1387)

Cable Inventory

Not a believer in cables hence none to speak of. Doesn't mean I don't believe in cable sound though - just that it should be taken out of the equation by other means than by rolling cables.

Power-Related Components

Own designed wideband mains filters using air-cored steel inductors.

Other Audio Equipment

Paiyon passive bookshelf monitors on stands

Audio-Related Tweaks

Mains balancing transformers (1kVA).

Music Preferences

Classical, acoustic rock, world, new age, jazz.
