HL tears the ES9038 DAC down to the bones for a full hardware upgrade! In stage 1 of upgrades, I worked on the analog side of the board, replacing nearly all the stock parts, including: resistors, DIP-8 sockets, and capacitors. The results have been impressive, giving a much more reference leaning tone. (ELNA SILMIC Super Gold included)
Tore down the AU-517 once again, to get at the Power & Protection circuit. I made a mistake in replacing the 10D7C silicon diodes and hoping this fixes the relay issue.
You can find the complete C-2 page here. Capacitors Used Include: ELNA SILMIC-II/SILMIC-II ARS/ToneRex, Nichicon Muse/Muse-ES/Fine Gold/FW and a Siemens/EPCOS 1uF MKP output capacitor. Previous Mod: 16V Zener Diode Mod to allow Modern Discrete Op-Amps from Burson Audio.
Finally got a balanced (XLR in) headphone amp. 2.8 MHz is native DSD64 converted by DOP (DSD over PCM). This is a picture from my phone, but I wanted to get something for readers to see on the reviews in progress between this combo and the Burson Play DAC/Amp combo. I plan to focus more […]
