Hello all....
Just want to tell you, that during the last weeks, I was able to build my first ProtoDAC.......and what should I say: I´m overwhelmed !!!!
I had NO idea, how brilliant this little DIY project will sound.
As I wrote in my "introduce myself" post, I´ve also reactivated my Sony Amp, only for Music-listening and spent some money for better Speaker-Cables (QED XT25).
That was the next Ah-Ha experience: even the cables made a BIG difference!!!!
The DAC for now is equipped with the "standard-parts" and it gives me goosebumps every time I sit and listen!
But (of course) I will tinker with some other parts......already got some Elna Silmic 2 for the Panasonics....will mix them maybe.
And there is a pair of Russian K 77 Polycarbonate Capacitors waiting.
I will order some other parts as well for further tests (HiFi-Collective has soooo much wonderful stuff!!!)......it´s really exciting!!!!
My platform is a RPI 3B+ and at first, I tried the latest MoodeAudio Version 9.0.4 (64Bit)
I am not really successful with it, as there is a lot of "stuttering" whilst playing music via Airplay!...no problems with the radio-stations....
I´ve read a post in this forum, talking about the same problem.
It sounds like a buffering issue.....changing the buffering didn't help.
Another thing was, that the left and right channel were swapped....
Some days ago I constantly ran into a system-freeze, only by changing the radio-channels....had to restart the RPI , but again freezing and now "out of phase"...
Then I swapped to the latest 8.3.9 Version, but this time 32Bit!
Well, that works (almost) like a charm!.......the stuttering appears only very few times, during a longer listening-session.
Channel and phase were correct right from the start and no freezing!
My idea is, that it´s a problem with only 1 GB of RAM in the RPI (especially in the comparisons between 64 and 32 BIT).
I will try to borrow a RPI 4 (4GB).....then we will see.
I also will follow Gabsters idea of feeding the DAC directly with the three U.fl-cables (and so without the three resistors) from the FiFoPI Q7.
A lot of "work" and big fun!!!!!
Thank you for your project!!!!!.....I will report again
