Thanks for the tips and tricks. Nice work. I have used your videos to bild a flagship streamer with an upgraded denafrips. Wonderful. The next project will be a Gabster td 1 DAC with a high quality TDA 1541A.
I had to look for this one found it Check This portion of a older Video where I talk about it not sure they still sell it but I love it I had to use a medicine container later on and make a bigger filter to avoid internal clogging I have it for 3 years and still works Great. here is a similar unit my model is no longer available looks to be the same s.click.aliexpress.com/e/_ol3ci1f and here is my Video th-cam.com/video/pAzcFoIEeLE/w-d-xo.htmlsi=YCL6o2ec3DY6n7wh&t=843
I would also prefer to use SMA connectors. It is much easier to plug and un-plug. Thing is that there is not sufficient space there for a bigger connector.
@@TedMa76 Lots of room, just make the PCB a little longer. For power use Amass XT60 for unipolar or Amass MR30 for bipolar. They come in right angle. XT90 if you really want lots of amps. For the lowest noise coax use B&K AC-0205 SUPER LOW NOISE COAXIAL CABLE
@@universeisundernoobligatio3283 I have already built the DAC but I would be very keen to change the UFLs inputs to bigger but much better SMAs. Why not sharing some photos in the DIY forum?
The funny thing is, that the professional audio analyzers which are the absolute pinnacle of precision with a near zero phase shift and a SNR in the range of -160dB, use standard DACs and ADCs in the $5-15 price range.
I have a FiiO FQ1222 and like it allot. Basic and performes well. The present unit by FiiO is the Q3. Mine is an older one with USB micro input. It has both 3pin and balanced 4pin output jacks on it and drives pretty much any reasonable in ear or over the ear headphones. I have also used it to drive my Kyogo Stax SR Lambda Pro headphones thru my NAD3020 amp and have been very happy with the sound. It is a cheap DAC for the features.
Make sure no crosstalk is happening between Capacitors and lock them together with silicone to reduce vibrations it is hard to tell if this yields to better sound but every small thing helps at the end when you add things up
What makes me laugh so hard is the simple fact that with modern AtoD and DtoA converters operating at 24-32 bits and 192k-320k samples per second you are orders of magnitude past what the human ear can perceive. With an old DAC like this and the low frequencies involved the output filters are far more involved and complicated compared to a simple RC low pass needed with a modern Delta Sigma converter and it's high sample rates. IE, you got allot more crap in front of the source with this than you do with a modern 1bit converter. Speaking of sources, a tone of recordings we all know and love were done on older professional consoles that used basic opamps of the time such as the TL07x and the NJR553x for all of the basic gain, filter, and summing blocks. There were literally many dozens of these in the signal path on most modern recordings back then. I should expect that a converter like this is warm and illicits fond memories of the sound we enjoyed from the equipment from back in the 80s and 90s. To be sure it is by no means true to the recordings though. I do admit to the appeal and fun if such an endeavor and even have a simple FET class A RIAA zero feedback preamp for my old Thornes turntable. Fun to play with and tweak but I am under no illusions that it is highly accurate. Enjoy.
That high order filter of old adc/dacs you mention was responsible for the cold harsh sound of the first generation of CD players btw. Higher sampling allows you to use better filters so you don't get phase and group delay issues like crazy in the higher, still audible band.
@@MsSinyria Depended on the filter and the components selected. Also, some of the first CD player even had 14 bit converters. Some of the early converters were truly crap as were the majority opamps at the time. These found their way into the vast majority of equipment of the time. The sound was trash compared to the quality hidden on the CD it's self and and most any middling quality turntable.
You should use a 0R resistor for the unused pin so no risks of Short circuit, the second option, is to use some kapton tape to be sure to avoid any short circuit
Hmm - worrying about a small screw on the outputs so that they don't touch anything on the circuit board, but first pointing at components with a metal screwdriver while the device is running should only be shown by real experts in the video.
I would love to build it but only thing that’s stopping me is a variation in quality and sound of the Philips chip. I’m not in a position to test several and it would bug the hell out of me knowing other chips may give a better sound🫠
Thanks!
Thank you for your support :)
I already have built my own. Great job @Gabster1. True audiohile sound!!!
Glad you like it Feel free to reach out by email if you like me to share and show your build on the Chanel

Hello! Did anyone build the flagship version of this diy DAC and compared it to popular non-diy DACs? Where would this stand?
Cambridge DAC Magic is one of the best, and costs less than a mortgage.
Very clever.
Gaby, do you have any videos where you show the vacuum setup (assuming filtered air) for your iron? I'm very curious/interested in that!

@@Gabster1 Thank you for sharing. It looks like a nice setup!
Use SMA connectors for the coax cables, much more robust connection, you can also use RG174 double shield cable.
good Ideas

@@universeisundernoobligatio3283 I would be interested to see this implementation with the SMAs. Why do you make with post on DIY forum?
Would you recommend two crc filters for the 5v+- side aswell?
If you are using a power supply with a long cord yes or UcCondtiiners if you do not mind using UC’s
@ I've built a studer900 +-5 which will sit pretty close so maybe not necessary? Thanks for reply!

Yes, and?
Is there an afordable DAC in the World for Headphones and Microphone? I only found 2 from siiht Audio...

What is pruprose of those shields between capacitors ?
Make sure no crosstalk is happening between Capacitors and lock them together with silicone to reduce vibrations it is hard to tell if this yields to better sound but every small thing helps at the end when you add things up
Does this have USB in? And coaxial/fiber optics in?
you can add a Input Card to the IanCanada Streamer like a DDC/Amanero combo

Rhodium plated Furutech RCAs are the best sonically I’ve ever tested, but very very expensive.
I designed the TD1 to fit those as long as they have the correct schematics

im step forward. with smps, yes , same ammount regulators, the smps win !!!!!!and long cables for clocks, not working perfectly!!!jitter!!!

If you can afford a S1 crown Chip most are great finding a dead CD player with one of those is almost always good
