Really a nice and smooth sounding device. Has got the Rochester DACs from Paddy, as the eBay ones run happily in the 1862 DAC.
Miro, do you accidentally know the power consumption of this DAC?

Hi Ernst, thanks for your review, enjoy the sound 🙂
The power consumption is around 500mA +-100mA?. I don't know the number exactly, it was a long time ago when I measured it, but I know that it was manageable for the USB 😎

Hi Miro, thank you! And, it is easily likeable.
I asked, because I think of an USB isolator. I always had some positive results with them in terms of noise, which was not noticable until it's fine. The one I have, is just able to deliver 200 mA and clearly not strong enough. I do not know me above 400 mA capability, at least without external powers.
I think, I have to measure exactly.
Have a good bank Holiday.
Cheer's, Ernst

Thought, I need to show this :-D.
The sound is really enjoyable, yet in the end a pair of LM6171 or opa123 will find its place.

Those AD1862s look so happy...
Did you prefer the LM6171 to the Bursons? I like the 6171s in Miro's DAC and thought about trying the Bursons, but after comparing many I liked the 627s so much I couldn't see spending even more.

Hi Paddy,
I put the Bursons in just for fun :-D , and in order to see, if the USB bus has enough power for them. And yes, there is enough juice. They do sound great in this little headphone DAC - relaxed, yet detailled. The Burson easily betters the opa134, which I listened for some time up to now in this DAC. I opened the box in order to change the 134 vs. the LM6171 the gain some listening experience.
The Burson has its regular place in the AD1862 DAC and later this week I will do some serious listening comparison with my just 3 pairs of single opamps. In my drawer there is no opa627, so no chance for me to compare.
Thanks again for the great AD1862 GB 🙂

Ernst, that is disgusting and that's why I almost never post my hifi porn picks !
Not saying than putting two Surimi sticks instead an oap is too much tweaking 😀
Nice job, very clean 🙂

Thanks for the big laugh Iggy - lol.
Ja, when I looked at the photo I also thougth, this has got a clean look. Especially after having to resolder the pcm2706 three times, the shift register at least once each and 3 of them twice, having to resolder and turn around the head amp chip and a few of the smd caps and the feedback resistors and caps - I think, therefor this is really a good result. Optically and soundwise.
On the one side this was somehow embarassing for me 😕 (and I must have had a bad day - for sure 😉 ) yet on the other side I am very happy having this accompolished in that way - with help from you guys and some solder luck.
Have to say again, Miro has created a great little headphone DAC.
Cheers, Ernst

Fantastic results Ernest! you will be very happy with the LM6171 and Burson's.
I don't have this board but would assume the sound is very similar to Miro's dedicated DAC boards.
If I'm using Miro's board with opamp I/V, I've settled on three "regular" opamps, LM6171, OPA627 and OPA1656(with adapter pcb) 😀

THT ???
Terrific Hot Too ??? Tehnically hiden tube ?
OK, nobody tried a Korg NUtube already salmon coupled for the color ! ( Ernst I will ask you PM about your discrete Burson V6 one day... curious !)

Noooo!!
Come on Miro, more SMD not less, LOL!! 🙂
Just kidding, I can appreciate both methods. A big issue currently affecting us is the low or no stock of many common parts, both THT and SMD, we use in this hobby.
Ah I understood, a Through Holes Thor version ! Drop a call Miro for advices on parts and how to push them into the vias, lol 🙂
I have just learned how to make pan cakes ! uH ! Hervé - Si bien du mal (Clip spécial confinement) - YouTube (I can solder parts on the pcb like this guys, next Marvel Movie to come...)

THT = The Hot Toy 😀
No worries guys, the parts will definitely be in stock gradually, stay positive

possible to make such emoticon but with aquavit or Bordeaux bottles... it begins to be hurtful to see always just beers...

Wow, curious how to locate the high number of THT parts on a similar sized PCB.
Paddy, I need more DAC chips ;-)
Vunce, the character is similar, yet there is slightly more noise. Have just listened via headphones, but may do via separate hpa today.
Cheers, Ernst
