Tiny Cmoy Headphone Amplifier (Part 2 Final) Using Lithium Battery

From my last update here, I found that using small lithium battery that I have take from the old toys is very durable and practical for this CMOY amplifier. Then I also adding the rechargeabe socket in this CMOY for more flexibility. Now this CMOY amplifier is just like a commercial amplifier available in the market.

I am using this CMOY amplifier often. I listen music at the office using this headphones amplifier.

The internal layout and components has been changed. I am not using SMD capacitor as input anymore. The mylar type capacitor is now put in place.

Roughly this amplifier can run 12 hours at normal listening level non-stop. When it comes to recharge the battery, I just plug to any 5 volt USB port available in the laptop. It is only require about 20 minutes to fully charge the battery.

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.

Signal Path Capacitor Comparison - Elna Cerafine Vs. Silmic II

I you following the discussion online, there are many endless debate about sound quality improvement from one capacitors to another. Some of them did a comparison between certain branded capacitors, which in my opinion, the result are very subjective. To make this comparison more crowded, so in this post will I adding another capacitor comparison. Previously I did a capacitor upgrade on the Pioneer KEH-P9750 head unit using Elna Silmic capacitor for the signal path only. I will take this opportunity to compare between the Elna Silmic II and the Elna Cerafine. Both capacitor are produced by the same company. I believe the result would be more objective.
