A blog about the journey of a DIY Audio enthusiast who doesn't care too much of the 'esoteric' ultra-priced commercial hifi equipment. I may be wrong, some or most of the time, but hey, it's my journey and I welcome you to share with me on that journey. Currently interested in headphones, open baffle speakers, full range drivers, tube amps and Pass Lab Class A designs.

Calyx Coffee - The Inside Story
On a roll, here are the innards of the Calyx Coffee. It appears from my causal observation that the headphone output is not driven by its own amp circuit, and is paralleled with the RCA outputs; which I presume is coupled by the Fine Gold caps directly to the ESS9023's output.
ESS9023P - DAC
Tenor TE7022L - USB Receiver
SC12.000 A1026 12 MHz clock
LD1117A - Adjustable regulator
Atmel ATMH038 - Some sort of Microprocessor to control the buttons
