|Headphone Amp Inventory
||No separate head-amps, all mine are integrated with multibit DACs. Currently I'm using AD815s but in the past have gone through AD8017 and AD8016.
||SD card players (QA550 and Taobao-sourced one using STM32F407) feeding homemade multibit DACs (TDA1545A, TDA1387) with massive cap arrays on the supplies and LC anti-image filters. I use old DVD players for S/PDIF sources.
