Hello Vunce, yes. Which i didnt expect. After trying out the new one, i have placed order for another unit last week.
Member Gaycoh has contacted JLSounds to enquire about the difference and JLSounds has mentioned that there is no difference in the isolation when two separate psu are used for the board. I was not tempted to get another board when i tried the previous board. Not that it does not sound good -- it sounds good to me. However when i tried the new FIO board this time, i feel it sounded much more refined than the previous board... and i started to think of getting another. I did not take much effort to discern the improvements of the new board.

Zoom just to clear things about JLSound boards differences old=jumpers configuration new=smd?
Is that what they call "fullly isolated" ? They call both Version III board on the website ?!
Hi, the means of configuration is still the same , using jumpers on header pins and also zero ohm resistors. However, when the new board is used as i2s, all the jumpers on header pins (connector H5, designated as J1-6) and the bridging zero ohm resistors (A-G) are left open.Zoom just to clear things about JLSound boards differences old=jumpers configuration new=smd?
What i am trying to bring up is that the way of connecting the jumpers and resistors for the new FIO versus the previous board is different.
Yes, i also wondered why Lyuben named them both as Version III. Anyway i think he may not be selling the older version any more.Is that what they call "fullly isolated" ? They call both Version III board on the website ?!
It has been out of stock for quite some time.
And that resistor R13 on Miro's board with JLSounds board on top is no longer required if one is using the new JLSounds board with the FIO designation.Hi, the means of configuration is still the same , using jumpers on header pins and also zero ohm resistors.

Is the physical fit onto the DAC board without shift registers preserved with the newest JLsounds version?
Any chance you compared 'PCM1704' direct without registers with I2S and shift registers?

Another day, another DAC project.
Just received my TDA1541 boards, along DC blocking and dual to single boards. Once I complete this one it will be three DIY DACs designed by @miro1360 that I have built. I am highly satisfied with the performance of AD1865 and AD1862 DACs I am sure I will be equally happy with TDA1541.
I couldnt find a reliable source locally to get TDA1541 so with luck found SONY CDP-750 and CD-950 both of them have TDA1541 not the A or S1, S2 version but still 1541. Bought both of them from local market for $10 and $15 and decided to sacrifice both of them and pull out TDA1541 chips.
Here are the sacrificial boards
SONY CDP950
SONY CDP-750
One of the 1541s
and the new PCBs
@miro1360 I have noticed that the dual to single boards can only be used for AD1862 and AD1865 DACs and not the 1541. Anyway miro I am thankful to you for your continuous support of DIY community and TBH the quality of DACs in terms of sound is better than most of the commercial DACs.

If tda 1541 non A chip, just omit to populate the DEM clocking cap between pin 15 and 16 cause already inside the chip.
Oups ....pin 16 to 17. Pin 15 is the - 15V
Ah, still waiting for the Wima/Epcos capacitors, so no harm done.🙂
At the most it would have been a pair of "via" lost.
But really appreciate your help, it's been fun on this board and in the recent years @miro1360 has added more color.
Because it is basically the same board, just differently isolates outputs. Chip is the same, software. And slightly different layout of components and pin headers so it's not 1:1 as before. You should check it, i don't think it can fit on ad1862 board anymore.Yes, i also wondered why Lyuben named them both as Version III.
"You should check it, i don't think it can fit on ad1862 board anymore."
Really?
If thats the case, such a bummer😢

There is ever so slight offset on H3 and H1, but big offset on H2 and H5. I can confirm next week, if nixie can bring his ad1862 board.
@rehanabid Exactly as @diyiggy mentioned, you can use the non A TDA1541, but without the C15 capacitor (if the pins 16-17 are not internally connected in the chip, you can mount the capacitor, but I don't have this information) 🙂
