I could use the same...

Hi,

I've actually been looking for this as well. I have a Resolution Audio CD-50 that uses four of the PCM63 DAC's, and I'd like to modify the lousy op-amp output to somthing more like what Nelson used in the D1.

My e-mail is: owen.columbus@littletreeaudio dot com

remove the word "dot" and put in a .

Cheers,
Owen

Hi there,

I'm a big fan of Passlabs and i would like to modify my denon dcd 1290 more in the passlabs way.
Or perhaps build a balanced DAC.
Could someone send me the schematics of it to?
Would sound nice with my Bosoz and mini alephs.

Thanx Richard

hello!
sorry for off topic but i am confused about d1 dac, and have question about chioce of regulators (lm7815, 7915 preregulator, 7805, 7905 local regulator) in this high quality product?😕

Not off topic at all... infact, it's the first proper D1 related question in the whole thread.

I finished a modified output board for my Resolution Audio CD50 a few months ago, and the standard issue National Semi LM regualtors have been working great for me. I mounted them on heatsinks to be safe, but I'm pretty sure you could get away without them.

There might be some advantage to using ultra-high quality regulators, but it's unlikely given the better than average power supply noise rejection of the balanced circuit. Either way, I can say for sure the LM regulators work fine, if you feel you need more than that, give it a shot.

Just a side note, I have a board design with the output stage if you'd like it. It might be a good start for you, all that you have to do is design the preceding DAC circuitry.

All the best with your project!

Thanks skseah.

Can I use this with TDA1545A too? I'm using the Charlize, anyone tried this? How's the difference between the R I/V and D1 I/V?

thanks! 🙂
