LME49720 Or NE5532 For Cmoy Headphones Amplifier?

Using a Cmoy amplifier is actually good enough to deliver a good sound through a headphones.

Building Cmoy amplifier is basically easy and cheap. For the comparison, I have been using Schiit Magni headphones amplifier and Cmoy amplifier sound quality is comparable

The designer of this Cmoy amplifier is based on one person name Chu Moy and the amplifier layout is basically an op-amp gain which very simple and not too much parts involved.

The standard op-amps for Cmoy amplifier is using NJM4560 that can deliver up to 70mA of current with minimum impedance output is 150 ohm. But how it sound if I compare to the others op-amps such as LME49720 or NE5532?

The specification for the LME47920 on paper is better than NE5532 and so does the sound quality.

On my listening test, the LME47920 sound more precise on every music instruments and noticeably pronounce better in the high frequency. While NE5532 sound more darker, a little roll off at the high frequency.

I could say that both LME47920 and NE5532 sound very natural yet dynamic. No others frequency are dominated and this is very good result from an amplifier should be.

My experience with others op-amps such as OPA275 or AD823 is they are good but somehow coloring the sound so much. It makes less enjoyable than listening with this LME49720 or NE5532.

The price different for both op-amps are huge. The of original NE5532 is less than US$1 each and the original LME49720 are about US$5 each.

Both op-amps are my recommendation for the best sounding Cmoy headphones amplifier.

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.
