thx for reply
have you tried dac with 4 or 8 tda1543 parellel
If I like to try It - do I have to do anything than stack Ics on top
also ecdesigns got another mod - floating power

Yes, I've tried parallel TDA1543's, I personally prefer single chip but I can understand why others do like parallel chips better
Stacked chips give more current, basically sounds louder with more bass if using a passive I/V stage
Its supposed to improve noise figures
To my ears parallel dacs didn't sound as natural, I found it robbed a lot of what makes these chips likeable , some will disagree which is ok, its just my opinion
Also I think stacking chips is best left to the newer types which tend to be much more tightly matched , theres a big variation between the older TDA types
Also paralleling these TDA1543's generate much more heat, the chips MUST be properly heatsinked, if you don't you'll reduce lifespan, these will go noisy after longterm use at high temps
hi everybody,
a little bit late but i bought this 1*TDA1543 + DIR9001.
i hope arrive soon.
certainly i will change all the elko capacitors with some more audiograde and the film capacitors with some russian PIO or PETP.
i'd like to build a PSU very silent like that you can see here:

ok, i know, the PSU cost will be 3 time the cost for the complete DAC but the advantage, maybe, will be guaranteed.
at least i hope, otherwise will be as throw the money in the dustbin.
what you think about?
thanks.
NOS dacs are evil.
Nice work Leo.

1543's are cheap and easy to use, they are a good starter into diy, start basic and work your way up

BTW I'm currently playing about with another NOS dac, its a diy Paradise Monica3, I'll post some details when its ready
Cheers,
Leo
