DAC build TDA1541A/SAA7220P/B *will take som time*

Mayday · 21st December 2011, 05:56 AM

Ordered the PCB and the first component today.
I like the sound from my Marantz CD-60, even if it's only partially modded, so I wanted that sound for my PC too.
This build will take some time as I'll gather parts as I can afford them..

This is the Analog Metrics PCB? If so it has a design flaw in that the replay clock (an XTAL OSC module) isn't locked to the SPDIF input resulting in skipped or duplicated samples every so often. Worth knowing that I feel before you begin to troubleshoot any clicks or glitches you encounter

It's this one

I've heard of people being very pleased with this, although that's been the complete kit.

Yep, that's the one. The people who are pleased with it can't have noticed the skipping or duplication of samples.

Is this something that can be fixed?

Not simply, because it would need something of a major redesign in regards to the clocking. Best have a listen for yourself and if you don't notice the defect then it won't matter.

Will do

Thanks for pointing it out though!

This will supply the I2S signal until I can afford better.
I'm hoping the coaxial out provides I2S....
