DIY Advanced DAC

[ujjwaana]

I was searching if somebody tested the waters of advanced DAC and saw only O2 Objective DAC thread.

Did any one tried advanced DAC like Sabre 9018/AK/Wolfson ? I am seriously looking for 2 channel 32bit DAC based on Sabre ES9018 with multiple input and variety of crossover. Most of decent kits/PCB sell for over $400 mark so was thinking to check if people out here tried something like these.

Subscribed. I am also looking to build one (DDDAC 1794 in particular), but everything seems to be upward of $350 not even considering standard upgrades. Would be very interested to hear what our DIY gurus have say...

If I'm not wrong you're looking for a multi-channel dac fed from a dsp/ digital-crossover and can feed an active speaker system with separate amps for each driver.

If my understanding is correct here is one such multi-channel implementation in the works.

You are bang-on on the exact project on DiyAudio. if you call 2.1 a multichannel, then you are right. the Sabre ES9801 benefits for having 8 channel DAC that can be put in various configuration. People have put it into separate 8-5 channel implementation, but I was looking for a robust implementation which implements more than one DAC in each of stereo channels and remaining for implementing X-over to sperate Sub out with configurable LPF/HPF cutoff for main L-R and Sub channels.

I come from Analog DIY of early 1990's era and left the hobby for sake of Studies (10/12th exams) and coming out of long exodus (with brief involvement in Engineering and other times). The Digital era was just breaking during mid 1990's with internet/ebay and unrestricted supply of just any component still unknown. So, working advanced DSP like Saber could pose a challenge for me. Though I already learned SMD soldering recently for a AD9051 based DDS VCO I am building to feed my old NR60 Transceiver (only Rx section as I dont have HAM licence). The below is the work in progress by me. This can give you some idea if I should be takign this DAV project.
