Nakamichi PA-100 Power Amplifier Installation

In this post will show to you my latest work on my car audio system.

The audio system on my Honda Brio is so simple. I want to keep this car as light as possible because I use this car mainly for commuting to work. For that reason, I just using the Pioneer AVH-G115DVD head unit and a pair of JBL GT7 coaxial speaker in the front channel only. With this simple audio system, is it sound good? Not really actually. It is sound metallic and thin on mid-range. Apparently this is the most today cheap car audio sounds like. Too much digital interference that suck up the soul from the music. I cannot expecting more.

So I think I want to improve it.

I still have the old-school Nakamichi PA-100 power amplifier that I think this would be sound better than the internal amplifier of the Pioneer head unit. Check it out.


The Nakamichi PA-100 here it is the older version of the PA-102. There is no difference in the amplification circuit between them. This PA-100 amplifier unit only deliver 14 watt per channel and doesn't require so much current like others amplifier. The positive power wiring in this unit is should taken from ACC power cable rather connect directly to the battery. This is to avoid too much battery drain from the amplifier circuit while the car engine is not running.

Nakamichi PA-100 is made in Japan. This is the original Nakamichi far before the acquisition to the Asian company. If you want to know deeper about the internal component of this amplifier, please check my post here.

I like the tiny size of this amplifier. This will give more flexibility to put this amplifier anywhere in the car. Like what I did now, installed this unit inside the center console. I secure the cable with cloth tape and it's really looks like the OEM installation.




So how is this amplifier sound performance?

Well, although this amplifier power output on paper is far smaller than the internal Pioneer head-unit, but the sound quality is far powerful and better.

The sound with this amplifier is smoother, especially on high frequency. No overshoot, no harshness. The mid range sound warm and far from digital analytical sound. The bass more pronounce and punchy which makes me forget this amplifier only 14 watt per channel.

I guess old Nakamichi amplifier still perform well and using this amplifier like completely like having a new audio system in my car.

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...
