in the last time i use:

Mini HI-FI 4X TDA1543 parallel connection NOS DAC S su eBay.it Other, Home Audio, Electronics

and

HI-FI Mini DAC TDA1543 DIR9001 NOS DAC ASSEMBLED MODULE su eBay.it Other, Home Audio, Electronics

both light modded.

i thing both have a great quality at low price.
i prefere the 1*TDA1543, more "warm" and nothing lost.

previously.........other 3 or 4 but in the nineties.

You dont need power supply :
Quote:
Come with High quality Encapsulated Power Transformers x1pcs ( 110V or 220V )
Just ask for the right voltage (110v or 220v)

To get a working Dac, you just need a source (with spdif or toslink), everything else is included.

To have a finished Dac, you need a box...

Thumbs up additionally...

and literally out-of-the-box (see pic) it sounds splendid... i have a Burson opamp and OPA627 that i'll try in those two for kicks in that third socket later today and let you know how the sound changes. Now need to find an old external hard drive chassis to put this in...

My romantic notion of spending big bucks on a bitchin' TT is tarnished now with this simple lovely sounding setup -> MacOSx86 netbook clone -> Buffalo NAS server -> ripped FLACs -> Airfoil -> Airport Express(s) -> toslink -> Gigawork DAC -> Primaluna integrated tubey. Listening lossless and wireless to Sinatra's "Nice n' Easy"... and it is indeed!

I have very good results with 2 lm4562ma as i/v + 2 lt1028cs8 on a 2 simple=>1 dual opamp on the third socket.

I'm about to try some LL1636 Lundahl transformers to shortcut the whole opamp circuitry. I know it triples the price of the dac, but passive output may be pretty rewarding! At least, I hope so...

Well, this DAC is invariably going to be working 80% of my listening or more, so the cost could easily be justified... looking very much forward to your results!

My new Burson dual is burning-in, don't want to judge for another 20hrs or so.
Ordered a couple of LM4562's for the I/V's based on your positive experience, $10 on ebay, why not?

Any other mod thoughts folks?

Tried both LM49720 and LM4562 in the I/V stages and i truly cannot hear a difference between the two. That's not to say i'm not happy however The Burson dual on the output sounds splendid now after 100+ hrs. twas a bit bright initially with my Maggies, but has warmed considerably.

Has anyone here had any experience with upgraded caps to replace the SMDs (a la Lampucera investigations on the previous rev board) they'd like to share?
