Recap Of The Year 2022

It is almost at the edge of year 2022.

As usual, I always do a recap for what I did in this year.

In this 2022, there is not many DAC project like what I did in 2021. The pandemic is slowly vanished and life continue back to normal. I am now spending most of my time working at the office and just having a little time for this hobby.

The other reason it is simply because I already exploring almost all popular vintage multibit DAC in 2021.

But there are few project I 've done this year which they are always be different.

I always exploring the new idea especially when implementing the DAC I built. The GIC filter is one of the new things for me which the result is quite spectacular. The others is using the vacuum tube output for the PCM1704 non-oversampling DAC and 24 bit USB XMOS digital receiver. The DAC with this implementation brings very natural sound.

I take this post cover with my previous built, is the ultimate AD1865NK DAC which I just open up the cover again and see inside.


Although there are so many DAC I built so far, somehow I still feel proud of this DAC. Not necessary because it was an expensive DAC built, or not even the best sounding yet, but this DAC was built with all my knowledge and the experience I got from previous years.

This DAC was first built on 2021, it using TDA1541 here, then I start implementing the best specification oversampling filter, the CXD1144 with AD1865 here, and later on I changed the analog output using GIC LPF filter here.


Looking back to the past few month, I start to built few DAC in a small form factor using freebee steel casing. I made them colorful and compact but not compromise to the sound quality.

What I did is simplify the DAC components that mostly the power supply section are consume a lot of space. By using the high quality and low profile power transformer is one of the recipe to get the same power supply performance as the complex one.



Looking forward to the year 2023, I think I will still exploring all about vintage multibit DAC. The sound quality result from this DAC never fails me.

The next year project will more likely focusing on the new method and the new implementation using remaining DAC IC that I had on my drawer and hopefully it become a better DAC.

That's all for the recap of the year 2022.

Welcoming 2023.

Cheers.

OPA1622 Vs. OPA627 High Performance Op-amps Comparison

This op-amps comparison topic is actually boring, but at the same time, many of us still curious about what others think about it. The reason is simply because of the op-amps variation are hundreds and they are depends by the implementation. The op-amps are considerably cheap and an interchangeable electronic components but they are not built for the same function. So in this discussion, I will focus on the modern Vs. vintage high performance op-amps in the simple non-inverting pre-amplifier gain stage.

Vintage Multibit R2R DAC Tier List

At the very beginning of this year, I committed to explore the best multi-bit R2R DAC. This is simply because I have plenty of the resources (from broken old unit CD player of course) and ability to build them up. If you think this kind a recycle from old un-used unit to become something useful, than I should stated myself giving contribute for greener world:) After all DAC that I built in this year, I think it is better for me to list them up again in one single page like this. Then I will rank them up in a simple tier list. The reason for this, so you all know what my opinion about of those vintage multibit R2R DAC especially in the sound quality.

TDA1543 DAC Review In 2021

It is a fine day and as usual I am reading and searching online contents related to almost anything I like. During my search, I stop to the few online forum discuss about a simple DAC using TDA1543 DAC IC. The discussion about this DAC was about 3 years ago, and the latest was about a year ago. Quite new and overall discussion about this DAC sound quality mostly are positive. It is interesting topic anyway especially I was built this TDA1543 DAC long time ago in 2016. At that time, I combine this DAC with Tripath amplifier  here  and  here  before it sold in 2019. That is also my first DIY DAC and I am quite enjoyed this DAC so much, at that time. The background story about this, previously I was using Sony Playstation SCPH-1002 as my reference CD Player. The reason I moved to this TDA1543 DAC is because the CD optic inside the Playstation is wear out and I cannot find the replacement for it. I pretty remember the sound quality of this TDA1543 DAC is quite comparable...
