Ultimate Balanced TD1 DAC by Johnny, a Gabster/ IanCanada build

[@SunnySue-q6q]

Thank you Johnny for sharing this incredible Gabster TD1 build it is a great inspiration on how to assemble all the IanCanada parts 20 ultracapacitors and off course the 2x Gabster TD1 dacs by Gaby I am still figuring up my build and you have built 2 Amazing Dacs already Kudos for sharing this awesome build

great build, a truly passionate audiophile, every detail has been thought of, simply great.

[@RickRuizAudio]

Very impressive build. 👍

Let's hear Jonny's system ‼️

[@00LongLong00]

Wow ❤

[@user-od9iz9cv1w]

Nicely done! Did you use iancanada clocks? I can imagine this sounds incredible and will compete with any commercial DAC at any price point. I use a TDA1541a S2 DAC with iancanada FIFO and Well Audio clocks. Output is lampizator 6np2 dual mono. I found good linear power supplies were improved with supercaps, so I imagine Johnny's all cap DAC would be awesome. I made extensive use of Blackgate caps throughout. That is another story that pairs well with this chip.

I use the ScPure clocks from Ian Canada

One word ....Super😅

[@jkalinna5607]

i have a Pi4 DAC it works fine

[@tee-jaythestereo-bargainph2120]

Hey Gabster are you all able to measure dac ? Thanks for thr video

[@edmundzed9870]

Measure??? hahhaha don't be silly. It would end his bla bla bla career in an instant

[@Gabster1]

I can perform measurements to a certain extent, but not with a high level of precision, as I don’t own expensive, high-end instruments. The truth is, most measurements fail to capture critical aspects like the relationship between the left and right channels, imaging, or holographic sound. Some DACs that measure exceptionally well may sound good, but not necessarily great. Ultimately, I prioritize sound quality first and use measurements as a secondary tool. It’s similar to tube amps or preamps-they often don’t measure well, yet they deliver outstanding sound.

[@edmundzed9870]

​@@Gabster1 Sure keep it on! BTW which DAC measures good but doesn't sound so good?

[@tee-jaythestereo-bargainph2120]

I am with ya on that one Gabster I have owned many dacs some measured good some didn't examples I had the topping D50s that measured way better than my schiit modi multibit but I prefered the Modi ! That was like 4 years ago but you are correct Can't measure everything ! D50s sounded thin to me and to bright ' I do believe measurements are important to an Extent One of my all time Favorite speakers at pricepoint Polk lsim 703 I sent them to GR research I told Danny i knew they were going to measure very good but some pep have called them boring ' So far the Polk lsim 703 has been the best speaker Danny has measured and they give his extream series A run for the Roses Danny's comment but I wanted better clarity ' Measurement only tell you how they measure not what they sound like '

[@tee-jaythestereo-bargainph2120]

Now I need to finish xover upgrade $1500 in parts alone 60 percent the way finished '

[@OCDHIFiGuy]

It's interesting how people think what components are used in the build are in any way associated with the sonic results. 😂...

[@crazyprayingmantis5596]

Audiophiles are truly bonkers, look at this thing? The best dac is no dac, no conversion is required

[@universeisundernoobligatio3283]

All these ultra caps so that you don't have to design a proper linear power supply, poor system design. Note the ultra caps have a 8000A short circuit current, major fire hazard.

[@topkho]

It’s the opposite. The ultracap is much better quality than any LPS. Yes, Ultracaps can be dangerous.

[@user-od9iz9cv1w]

@@topkho Agreed. There is something to be gained with supercaps on digital circuits. I build my best linear power supply, then add a super cap for filtering and the sound improves by no small amount. iancanada tried this vs battery vs pure ultracap and found the latter to be the best.

[@universeisundernoobligatio3283]

@@topkho Define quality in what way? Give me some engineering units? Been using 3000F Maxwell super caps for designs for years. They are great for high cycle life and high current applications, but poor energy density. Low on resistance but you need large gauge wires to take advantage of that, 4awg or larger. In this application the small wires, fuse and PCB conductor resistance cancel that advantage. A better choice would be 1860 cells right on the DAC, shot conductor lengths plus better voltage regulation and stabilty. Capacitor voltage delta is V=(IT)/C always dropping under load.
