I didn't know this one !
For sure I will try it as I like drinking wines for all over the world when I have the opportunity !
Defintly no sigma-delta but an alpha to omega cheese one ! 😎

Any ideia about the buffer circuit?My friends are using in a 1704 dac the 861 as I/V, but with a simple discreet fet output, with loads of duelund.. 🙂
[emoji6][emoji6]
Anyone using 1000pf, and other values instead of 47pf? Or no cap??
What is the relation between the value of the resistor and the cap?
Did you end up testing different cap values?
Hello laserscrape, i tested 1000pf. I think i did not win anything over the 47pf. Tested two different 1000pf caps.Did you end up testing different cap values?
In my setup the tda1541a with a 150 R at the outputt of the opa861 as buf. was a very good improvment but only in 1/8 W , the 1/4, 1/2 w were very different !
Not mettalic in my setup, nore mellow, I believe the 150 R is not a big value at the output but I can hear eac resistor I tried there from tantalum to Dale Rn55 (the worst for me) and many else ! I believe the very thin leads of the 1/8W where for something related to my whole setup ! I must say the tda1541a dac is dc coupled : no traffo, no caps : sounds are so subtle but still hearable I had to avoid any soldering of this resistr cause the solder whatever the comp (silver 4% the worst) wasted the perfect equilibrium it gave (I repeat : in my setup) !
Despite it's carbon comp it sounds right to my ears : maybe some H3 trace or a little distorss : but again 150 R is very few but that R is mandatory for best results. (The R of the I/V is a Rohpoint ayrton Perry wirewound 516G) : the fact there is not the small loopback cap in the buffer sounds better too if the whole setup or headphones is sensible enough to that changes.
If metallic : look at & focus on the supply and decoupling (and the source quality too).
At the end those smal details have to be adapted and worked for each of us in relation to their whole setup by ears...
R8 : try to 1K to see if different than the 830R in your case - I mean still with no outpout 861 buf- I believe the 200R with the 861 but in between is also too much little but at each to find the equilibrium he likes most : that's an easy way to tune that playing a little with passive parts and supply here to reach his subjectives liked tastes 🙂 Nothing writen in the marble but if you measure only which is not the final goal of a NOS DAC. Imho, YMMV ! 🙂
hello diyiggy, i did not found that rohpoint resistor you mention, are you sure is 516g?
Hi,
It is the 8G16 but the GG102 squared is said even better, but not tried the squared... difference is certainly hard to hear.

There were 5G & 8G at Farnell long time ago...

Thks diyiggy i will check them![emoji6][emoji6][emoji106]Hi,

You can order directly from their website,even it does not always work. Most time it does and it is expensive. Cheers!
I liked the first one so much I built a second for my father: Miro's board with 6171s (we'll try some others, I can't see him paying $28 per op amp for 627s 🙂 ), Pass B1 buffer and an Academy Audio Muses control for volume, 3e 3251 amp and a Meanwell 24v power supply.
The wiring isn't going to win any contests but it sounds pretty nice and you can't see through the case anyway. This is my second case from Landfall Systems, I really like them - built like a tank, easy to machine, and made by real people in Texas. (I spec'd it to sit tall but ended up setting it down on the long side, so the face place doesn't hide the sides like it would if I used the long side as the face)

That's coooool as we say here, cold people not from Texas 😀
The dad can be proud of his son, yah! 🙂 😎
Well done.

@Paddy Garcia Well done!
Every son wants to please the father, so it must sound really perfect when your father deserved it!

Nice job Paddy!
You’ve got lots of goodies packed in that chassis.
I’m sure your dad will love it 😉

Hi All, if anyone is looking for boards, please add your name to the Spreadsheet on the group buy here miro1360 AD1862 DAC PCB. I've let this slide for a bit, but I'm ready to move forward with it.
Also send me your address by PM and I'll get the total cost back including shipping, to get your approval before I submit the order.
Thanks

Following on with MrSlim's excellent GB for boards, I'm willing to do one more order from Rochester Electronics if there's enough interest: Another Rochester AD1862N group buy?
Hi,
Can someone could kindly help to buy Rhopoint GG102?
I have sent an enquiry, but no reply from Rhopoint

i2s help
Hi can someone help me how to connect this board to my hifiberry dac+ pro that has i2s out. There are 5 pins GND, Master CLK, Bit CLK, Frame CLK, Data. Im not entirely sure where the LRCK goes to Frame or Master CLK? This is just temporary solution to test dac board befor making it final setup. Thx
