[QUOTE="paulmarinis, post: 1058164870, member: 4254"] μεχρι τωρα εβαλα απλα ενα dual dc power supply απο ebay για την τροφοδοσια, και πηρα ενα αλλο οπαμπ ΤΗΣ4032 και θα το δοκιμασω το ΣΚ παρακολουθω τωρα και το θεμα στο diyaudio για αυτο κιτ , και ενας το εχει παει πολυ μακρια, εχει κανει τα εξης... please let me summarize the mods, they include improved power supplies including more on-board local regulators for some parts of the circuitry, a very special and very critical power supply called AVCC, new analog output circuitry including current to voltage conversion (I/V) and differential summing stages, a new clock, an external upsampling board, an Arduino microcontroller to augment digital control of the DAC chip, and a modified cheap ebay LME49600 headphone amp to clearly hear DAC sound quality performance (the 1/8" jack on the board loads down the opamp and should not be used for headphones). ..... θα δοκιμασω να κανω και εγω καπια απο αυτα....αλλα δεν ειμαι τοσο εμπειρος ακομα, και μου φαινονται καπως περιπλοκα καπια απο αυτα:) [/QUOTE]
