Default DAC Kits

Does anyone have any experience with the Audio Note DAC 1.1 kit? Or anyother DAC kits for that matter? It is time to upgrade my aging CD player!

You could try this: TDA1541/SAA7220 replacement board
or this: http://www.geocities.com/d_broadhurst/24bitdac.html
I built David's DAC and I'm very happy with the results.

Default confused

HP,

I am somewhat confused with your reply - the two links seem to point to two different projects. You built D. Broadhursts, right? What about the one on JH post? Looks simpler, cleaner.

This has me interested!

David's board is complete DAC with I/V stage, output stage,and all regulators. It's really good DAC, I've built it so I can tell.
Jocko board is using the same chips but doesn't include everything. You need your own I/V stage, output stage and maybe more regulators. This board is perfect for installing in an existing player as an upgrade. E-mail Jocko for details.
Broadhurst board is good for building DAC from scratch, because it contains everything you need. However it's not silk-screened.

Jocko's board is perfect for using Pass Labs D1 output stage then. I might use his board in my CD PRO transport if I won't like AD 1865K chips.

Mine's better. Just ask Hairy Holler.....he listens to one. Of course, he would not admit to either.

Speaking of which......I'm not here to make $$$, contrary to the suggestions of that annoying twit "Ren Hoek", but I do have bills to pay. So.......who might be intersested in the following boards:

1.) Receiver board w/DIR1704, transformer isolated differential input stage.

2.) I/V and buffer board, possibly with differential outputs.

If I get enough interest, I might whip some up. Might even put in some secret topologies if you guys ask nice.

Jocko,

P.S. What about input switching?

Hi Jocko,

Count me in as well. The I/V convertor with balanced outputs interests me as well. How about a buffer (BOSOZ, Aleph) after a 4gang volume control (no preamp)...

Best Regards,

Dale

Default dac's

Jocko,

I prefer the seperate board approach - that would let me experiment with different output stages, etc.

If you decide to 'whip something up', count me in!
