Welcome To THE ORRONOCO AUDIO DIY

Welcome to ORRONOCO

My journey into electronics started with a childhood habit of taking apart my parents' flashlights, phones, and stereos just to see how they worked. By the '90s, I was building beginner electronic kits from local bookstores, and it wasn't long before I picked up a soldering iron to build my first power supply.

When I successfully built my first amplifier—playing music from a portable cassette player through a speaker inside a plastic cup—I knew I was hooked on audio for life.

ORRONOCO is my personal notebook for my DIY audio journey. I created this space to share reviews, documentation, and builds born out of a pure love for audio gear. I hope you find some inspiration here for your own projects, or at least a bit of entertainment!

Featured Build: Point-to-Point LM1875 Gainclone

The amplifier pictured below is a dual-mono LM1875 Gainclone. Tired of the layout and size limitations of commercial PCBs, I challenged myself to build this solid-state amp using point-to-point wiring, inspired by vintage tube amplifiers.

It looks beautiful and sounds fantastic, but because I built it years ago, the assembly process went undocumented. This blog is my way of making sure the stories behind my future builds never get lost again.

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...
