There are 3 circuit boards, one for the receiver DIR1701, one for the DAC and one for a second filter for balanced outputs.
I made separate boards for easier upgrade in the future..
The result is fantastic, I'm hearing details I couldn't hear before. Well done Burr Brown - TI.
IC used: PCM1730, DIR1701, OPA627
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
