"Reference" TDA1541A DAC with I2S-BUS architecture

[studiostevus]

SWEET!

Has anyone tried the ecdesigns mk7 output scheme?

[studiostevus]

Oh, something else: would it be possible to optimize board size so another board (eg teralink x2) can be stacked on top?

Most of us will be struggling to fit it into an enclosure, so we need to be efficient with floorspace

Hmm, nice board. Would be in for at least one.

Hi Ernst, i thought you had build ecdesigns output stage already. Can you share experiences?

[ernesternest]

Hi , I've built MK4 - a long time ago. Since just after finishing John published MK5 due to a kind of failure in MK4, I stopped listening. Sound was not bad at all, but my tubed AD1865 was better for my ears. So the TDA1541 has been laying around, waitin' for a better I/V. Just got all the parts for MK7 and have started to build it on a veroboard. Later then I'll build Johns newest PSU for his DAC. His approach seems good to me. All in all Olivers newest board will be perfect for me

That looks like immersion silver, Oliver?

Nice board. Great to see a nice simple i/v stage on there too. I'll take one!

Excellent news Oliver

I've been secretly waiting for this to happen.

Btw you have pm.

Hallo Oliver

I a"m alway 's in for something new, as long as there 's is evaluation with the fellow
diy member' s. The current set of board 's giving me a hard time finding a cabinet. sound is ok.
I am in for a new board.

Ok... This may be too far out for many, but since i cannot do any physical mods at the moment due to my medical situation, i am forced to perform my mods in the mental domain only.

So... Here goes.... I am using 2 tda's in parallel. Would it make sense to power these with separate voltage rails (so 2 times +5/-5/+/-15v)?

Also, anybody experimented with instead of paralleling them, using them balanced (eg with i2s splitter), and followed by a balanced output stage (eg pass d1)?

Too far out for me.

2 TDA1541As in parallel is luxurious. glorious and sumptuous. It's also impossible to get trans-conductance, as they pull precisely the same volts/amps for each millisecond you might measure, so 2 supplies makes no sense to me whatsoever.

Balanced I know little of. I never quite saw the point, considering the enormous extra cost.

All the best
