low budget dacs

Thanks Paul!

I did a print to pdf printer dump and will have a nice read.

the description mentions the LT-1057 op amps are used
for better sound quality. original OPA2604 are still included.

interesting they give you extra chips to play with.

It's a great deal... There's better out there but you have to spend much more money, and it is not that much better.

Burr Brown eval boards

Have a look at this. It's no slouch! 24/192. Differential output.
Comes with OPA627's too. It's $399. Part nrs are DEM-DAI1704
and DEM-DAI1706.

I own the A/D board DEM-DAI1804, it was $299 and I am *VERY*
pleased. It uses THICK glass epoxy. Cerafine gold-red grade
electrolytics everywhere. Polypropylene film bypass on all over
the analog side, Digital side uses TANTALUM bypasses! Op-amps
are SOCKETED 8-pin DIPs using Augat mil-spec sockets. For an
eval board, these things are top-notch right out of the box. I'd
not hesitate to try out the D/A boards as well. I use my A/D
to sample vinyl, among other things.

The PDFs show the board layouts... Completely separate
digital and analog power busses. Thick ground plane too.

Yep.

Most Eval boards are the best implementations I say.

Hi,

I read through the posts of the Zhaolu 2.5 mod.

There was one post about the Aleph P1.7.

I'm almost finished with the Aleph P1.7. Could I bypass
the opamp of the 2.5c and tie the dac output directly
to the P1.7?
